Public Health Image Library  

NSDL National Science Digital Library

The Public Health Image Library (PHIL) offered by the Centers for Disease Control and Prevention (CDC) is an extensive collection of images and multimedia files related to public health. If you've ever wanted to see the life cycle of a hookworm or pictures of anthrax lesions, you can see them here. The site can be searched by category, keyword, or image id number, and although the Java-based search engine is a bit cumbersome, spending several hours here will be easy. Often graphic, many of the images are of diseased organs and microscopic slides. Educators, researchers, and professionals should find this site interesting.

Planetary Image Geometry Library  

NASA Technical Reports Server (NTRS)

The Planetary Image Geometry (PIG) library is a multi-mission library used for projecting images (EDRs, or Experiment Data Records) and managing their geometry for in-situ missions. A collection of models describes cameras and their articulation, allowing application programs such as mosaickers, terrain generators, and pointing correction tools to be written in a multi-mission manner, without any knowledge of parameters specific to the supported missions. Camera model objects allow transformation of image coordinates to and from view vectors in XYZ space. Pointing models, specific to each mission, describe how to orient the camera models based on telemetry or other information. Surface models describe the surface in general terms. Coordinate system objects manage the various coordinate systems involved in most missions. File objects manage access to metadata (labels, including telemetry information) in the input EDRs and RDRs (Reduced Data Records). Label models manage metadata information in output files. Site objects keep track of different locations where the spacecraft might be at a given time. Radiometry models allow correction of radiometry for an image. Mission objects contain basic mission parameters. Pointing adjustment ("nav") files allow pointing to be corrected. The object-oriented structure (C++) makes it easy to subclass just the pieces of the library that are truly mission-specific. Typically, this involves just the pointing model and coordinate systems, and parts of the file model. Once the library was developed (initially for Mars Polar Lander, MPL), adding new missions ranged from two days to a few months, resulting in significant cost savings as compared to rewriting all the application programs for each mission. Currently supported missions include Mars Pathfinder (MPF), MPL, Mars Exploration Rover (MER), Phoenix, and Mars Science Lab (MSL). Applications based on this library create the majority of operational image RDRs for those missions. A Java wrapper around the library allows parts of it to be used from Java code (via a native JNI interface). Future conversions of all or part of the library to Java are contemplated.

PHDIL: Philadelphia Historical Digital Image Library  

NSDL National Science Digital Library

A collaborative project by Thomas Jefferson University and the Pennsylvania Historical Society, the Philadelphia Historical Digital Image Library (PHDIL) consists of almost 3,000 pictures. Thomas Jefferson University, founded in 1824, is the oldest private medical school in the country, and the images in PHDIL come from its Scott Memorial Library, providing visual images related to the study of medicine -- portraits of alumni, faculty, and trustees; scenes from hospitals; views of anatomy labs; nurses at work; and medical society and class portraits. The Pennsylvania Historical Society was also founded in 1824, and the images that it has contributed to PHDIL document Philadelphia history and complement those from Thomas Jefferson University, including views of hospitals from newspapers and commercial photographers, as well as scenes of everyday life in Philadelphia at the turn of the century. An additional highlight is a large number of Benjamin Ridgeway Evans watercolor drawings of Philadelphia buildings and streetscapes dated between 1859 and 1885. Drop down menus at the search interface permit users to view pictures by selecting from a list of the subjects covered in PHDIL (choosing "hospitals" retrieves 861 hits), and also by type (carte de visite, drawing, cityscape, lithograph, etc.), creator or donor name, event, or date.

ISee: perceptual features for image library navigation  

NASA Astrophysics Data System (ADS)

To develop more satisfying image navigation systems, we need tools to construct a semantic bridge between the user and the database. In this paper we present an image indexing scheme and a query language, which allow the user to introduce a cognitive dimension to the search. At an abstract level, this approach consists of: 1) learning the natural language that humans speak to communicate their semantic experience of images, 2) understand the relationships between this language and objective measurable image attributes, and then 3) develop the corresponding feature extraction schemes. In our previous work we have conducted a number of subjective experiments in which we asked human subjects to group images, and then explain verbally why they did so. The results of this study indicated that part of the abstraction involved in image interpretation is often driven by semantic categories, which can be broken into more tangible semantic entities, i.e. objective semantic indicators. By analyzing our experimental data, we identified some candidate semantic categories (i.e. portraits, people, crowds, cityscapes, landscapes, etc.), discovered their underlying semantic indicators (i.e. skin, sky, water, object, etc.), and derived important low-level image descriptors accounting for our perception of these indicators. In our recent work we have used these findings to develop a set of image features that match the way humans communicate image meaning, and a semantic-friendly query language for browsing and searching diverse collections of images. We have implemented our approach into an Internet search engine, ISee, and tested it on a large number of images. The results we obtained are very promising.

Butler University Irwin Library Images Collection  

NSDL National Science Digital Library

What is mid-century modernism? Some might only be acquainted with it via the popular TV show, Mad Men, or others through well-known structures such as the World Trade Towers. Modernism sprang up all over the world from the 1950s to the 1970s, and one rather fine example can be found on the campus of Butler University in Indianapolis. This most wonderful digital collection presents images and plans for the modernist Irwin Library, crafted by noted architect, Minoru Yamasaki. On the site, visitors can make their way through dozens of images that tell the story of this rather unique building, along with offering up images of Yamasaki at the dedication as well as students using the building for various activities, even studying.

Images1: Online Images from The National Library of Australia's Pictorial Collection  

NSDL National Science Digital Library

At this site users can search and browse through 20,000 digital images selected from the roughly half million pictures in the Pictorial Collection of the National Library of Australia. Images1 includes portraits, photographs, paintings and prints related to the history of Australia. Three search methods are provided: Quick Search, a keyword search; Simple Search, to indicate where the search word should occur, such as Title, Subject, or Format; and Advanced Search for combining terms from several indexes. Those unfamiliar with Australian history can check the About page for information on the contents of Images1. Another very good way to approach the collection is to select the Browse Series Titles option, which produces a list of titles of the major groupings within the collection, and how many items each contains. For example, the Rex Nan Kivell collection is 3,000 pictures collected by Nan Kivell, a London art dealer, that document the early history and exploration of New Zealand and Australia.

Spectral library searching and FTIR/FT-Raman spectroscopies: effects of resolution and search algorithms  

NASA Astrophysics Data System (ADS)

Commercial infrared and Raman spectral libraries are generally only available at 16 cm-1 resolution by 8-bit ordinate precision. This is relatively low resolution compared to the typical spectrum acquired at 4 cm-1 by 16-bit precision. The low resolution format for libraries was selected to optimize library search speeds and reduce computer hardware requirements. Full 4 cm-1 spectral libraries offer a number of advantages including the positive identification of closely related compounds and greatly improved results when using spectral subtractions.

Semantically Enriching the Search System of a Music Digital Library  

NASA Astrophysics Data System (ADS)

Traditional search systems are usually based on keywords, a very simple and convenient mechanism to express a need for information. This is the most popular way of searching the Web, although it is not always an easy task to accurately summarize a natural language query in a few keywords. Working with keywords means losing the context, which is the only thing that can help us deal with ambiguity. This is the biggest problem of keyword-based systems. Semantic Web technologies seem a perfect solution to this problem, since they make it possible to represent the semantics of a given domain. In this chapter, we present three projects, Harmos, Semusici and Cantiga, whose aim is to provide access to a music digital library. We will describe two search systems, a traditional one and a semantic one, developed in the context of these projects and compare them in terms of usability and effectiveness.

Substance identification based on transmission THz spectra using library search  

NASA Astrophysics Data System (ADS)

Over recent years terahertz spectroscopy has become a new tool for the characterization of solid materials, in particular for investigating polymorphism and crystallinity in pharmaceutics. Search strategies have been tested for THz spectra of various organic compounds with their spectra taken from the Riken database (http://www.riken.jp), using the GRAMS spectroscopy software. A subset of the entire database was used, which had been processed by removal of atmospheric water vapour lines and smoothing applied based on Savitzky-Golay convolution or time domain filtering. The spectral range available for all library substances was restricted to an interval from 0.9 to 4.5 THz (30-150 cm-1). The number of vibrational bands within this spectral range is much reduced compared with mid-infrared or Raman spectra. The appropriateness of spectral pre-treatment is demonstrated with regard to reliability and robustness of the search methods. In particular, time-domain filters for smoothing and pre-treatment by the removal of water lines and etalon effects have been successfully tested in combination with least squares and correlation methods. With these insights, applications for substance identification, especially for the pharmaceutical industry, may be enlarged.

This cornucopia contains thousands of images from the Philadelphiana Collection at the Free Library, and most of them are from the second half of the 19th century. On the homepage, visitors will note that they can look around by Neighborhoods, Photographers, and Media. First-time visitors should look around neighborhoods such as Society Hill, Farmount, and Chinatown. The Chinatown area contains some rare images of the Philadelphia College of Pharmacy and local businesses that include the James Spear Stove and Heating Company. Moving on, the Collections area here offers up images that found their way into the 1976 book "Old Philadelphia in Early Photographs." There are over 175 photos here that offer views of Queen Street and the fabulous Wanamaker's store at 13th and Market.

Eclipse: ESO C Library for an Image Processing Software Environment  

NASA Astrophysics Data System (ADS)

Written in ANSI C, eclipse is a library offering numerous services related to astronomical image processing: FITS data access, various image and cube loading methods, binary image handling and filtering (including convolution and morphological filters), 2-D cross-correlation, connected components, cube and image arithmetic, dead pixel detection and correction, object detection, data extraction, flat-fielding with robust fit, image generation, statistics, photometry, image-space resampling, image combination, and cube stacking. It also contains support for mathematical tools like random number generation, FFT, curve fitting, matrices, fast median computation, and point-pattern matching. The main feature of this library is its ability to handle large amounts of input data (up to 2GB in the current version) regardless of the amount of memory and swap available on the local machine. Another feature is the very high speed allowed by optimized C, making it an ideal base tool for programming efficient number-crunching applications, e.g., on parallel (Beowulf) systems.

Mediated search services, usually offered for a fee, are commonplace in academic health sciences libraries. At the same time, users of these services have numerous self-service options available to them; for example, CD-ROMs and locally mounted databases. In keeping with its philosophy of access to rather than ownership of information, the University of Washington Health Sciences Library and Information Center (HSLIC) changed its policy from charging clients for mediated searching to offering mediated searches as an essential service of the library. By taking this step, HSLIC moved closer to becoming a true "library without walls." This paper describes HSLIC's experience with changing its policy and examines the issues surrounding use of the collection budget to subsidize access to online information in academic health sciences libraries.

Search prefilters to assist in library searching of infrared spectra of automotive clear coats.  

PubMed

Clear coat searches of the infrared (IR) spectral library of the paint data query (PDQ) forensic database often generate an unusable number of hits that span multiple manufacturers, assembly plants, and years. To improve the accuracy of the hit list, pattern recognition methods have been used to develop search prefilters (i.e., principal component models) that differentiate between similar but non-identical IR spectra of clear coats on the basis of manufacturer (e.g., General Motors, Ford, Chrysler) or assembly plant. A two step procedure to develop these search prefilters was employed. First, the discrete wavelet transform was used to decompose each IR spectrum into wavelet coefficients to enhance subtle but significant features in the spectral data. Second, a genetic algorithm for IR spectral pattern recognition was employed to identify wavelet coefficients characteristic of the manufacturer or assembly plant of the vehicle. Even in challenging trials where the paint samples evaluated were all from the same manufacturer (General Motors) within a limited production year range (2000-2006), the respective assembly plant of the vehicle was correctly identified. Search prefilters to identify assembly plants were successfully validated using 10 blind samples provided by the Royal Canadian Mounted Police (RCMP) as part of a study to populate PDQ to current production years, whereas the search prefilter to discriminate among automobile manufacturers was successfully validated using IR spectra obtained directly from the PDQ database.

Solar System object image search: A precovery search engine  

NASA Astrophysics Data System (ADS)

While regular archive searches can find images at a fixed location, they cannot find images of moving targets such as asteroids or comets. The Solar System Object Image Search (SSOIS) at the Canadian Astronomy Data Centre allows users to search for images of moving objects, allowing precoveries. SSOIS accepts as input either a list of observations, an object designation, a set of orbital elements, or a user-generated ephemeris for an object. It then searches for observations of that object over a range of dates. The user is then presented with a list of images containing that object from a variety of archives. Initially created to search the CFHT MegaCam archive, SSOIS has been extended to other telescopes including Gemini, Subaru/SuprimeCam, HST, the SDSS, AAT, the ESO telescopes, and the NOAO telescopes (KPNO/CTIO/WIYN), for a total of 7.6 million images. The SSOIS tool is located on the web at http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/ssois/.

Pattern recognition-assisted infrared library searching of automotive clear coats.  

PubMed

Pattern recognition techniques have been developed to search the infrared (IR) spectral libraries of the paint data query (PDQ) database to differentiate between similar but nonidentical IR clear coat paint spectra. The library search system consists of two separate but interrelated components: search prefilters to reduce the size of the IR library to a specific assembly plant or plants corresponding to the unknown paint sample and a cross-correlation searching algorithm to identify IR spectra most similar to the unknown in the subset of spectra identified by the prefilters. To develop search prefilters with the necessary degree of accuracy, IR spectra from the PDQ database were preprocessed using wavelets to enhance subtle but significant features in the data. Wavelet coefficients characteristic of the assembly plant of the vehicle were identified using a genetic algorithm for pattern recognition and feature selection. A search algorithm was then used to cross-correlate the unknown with each IR spectrum in the subset of library spectra identified by the search prefilters. Each cross-correlated IR spectrum was simultaneously compared to an autocorrelated IR spectrum of the unknown using several spectral windows that span different regions of the cross-correlated and autocorrelated data from the midpoint. The top five hits identified in each search window are compiled, and a histogram is computed that summarizes the frequency of occurrence for each selected library sample. The five library samples with the highest frequency of occurrence are selected as potential hits. Even in challenging trials where the clear coat paint samples evaluated were all the same make (e.g., General Motors) within a limited production year range, the model of the automobile from which the unknown paint sample was obtained could be identified from its IR spectrum.

Histology image search using multimodal fusion.  

PubMed

This work proposes a histology image indexing strategy based on multimodal representations obtained from the combination of visual features and associated semantic annotations. Both data modalities are complementary information sources for an image retrieval system, since visual features lack explicit semantic information and semantic terms do not usually describe the visual appearance of images. The paper proposes a novel strategy to build a fused image representation using matrix factorization algorithms and data reconstruction principles to generate a set of multimodal features. The methodology can seamlessly recover the multimodal representation of images without semantic annotations, allowing us to index new images using visual features only, and also accepting single example images as queries. Experimental evaluations on three different histology image data sets show that our strategy is a simple, yet effective approach to building multimodal representations for histology image search, and outperforms the response of the popular late fusion approach to combine information.

Personalizing Image Search Results on Flickr  

E-print Network

The social media site Flickr allows users to upload their photos, annotate them with tags, submit them to groups, and also to form social networks by adding other users as contacts. Flickr offers multiple ways of browsing or searching it. One option is tag search, which returns all images tagged with a specific keyword. If the keyword is ambiguous, e.g., ``beetle'' could mean an insect or a car, tag search results will include many images that are not relevant to the sense the user had in mind when executing the query. We claim that users express their photography interests through the metadata they add in the form of contacts and image annotations. We show how to exploit this metadata to personalize search results for the user, thereby improving search performance. First, we show that we can significantly improve search precision by filtering tag search results by user's contacts or a larger social network that includes those contact's contacts. Secondly, we describe a probabilistic model that takes advantag...

This paper describes the experience of an academic health sciences library which made BRS/After Dark, an end user search service, available to its clientele as a complement to its mediated search service. The library environment, initial publicity efforts and administrative procedures are discussed. An attempt is made to evaluate the usefulness of the service in a library environment. This evaluation, covering a three-month period, is based on the observations of the librarians administering the service and an exit interview conducted with searchers over a two-month period. User satisfaction, both observed and recorded, was quite high; however, the librarians found that users had more difficulty in constructing appropriate search strategies than had been anticipated. Overall, the service is assessed as highly useful. PMID:10271170

Efficient reduction of candidate matches in peptide spectrum library searching using the top k most intense peaks.  

PubMed

Spectral library searching is a popular approach for MS/MS-based peptide identification. Because the size of spectral libraries continues to grow, the performance of searching algorithms is an important issue. This technical note introduces a strategy based on a minimum shared peak count between two spectra to reduce the set of admissible candidate spectra when issuing a query. A theoretical validation through time complexity analysis and an experimental validation based on an implementation of the candidate reduction strategy show that the approach can achieve a reduction of the set of candidate spectra by (at least) an order of magnitude, resulting in a significant improvement in the speed of the search. Meanwhile, more than 99% of the positive search results is retained. This efficient strategy to drastically improve the speed of spectral library searching with a negligible loss of sensitivity can be applied to any current spectral library search tool, irrespective of the employed similarity metric.

Virage image search engine: an open framework for image management  

NASA Astrophysics Data System (ADS)

Until recently, the management of large image databases has relied exclusively on manually entered alphanumeric annotations. Systems are beginning to emerge in both the research and commercial sectors based on 'content-based' image retrieval, a technique which explicitly manages image assets by directly representing their visual attributes. The Virage image search engine provides an open framework for building such systems. The Virage engine expresses visual features as image 'primitives.' Primitives can be very general (such as color, shape, or texture) or quite domain specific (face recognition, cancer cell detection, etc.). The basic philosophy underlying this architecture is a transformation from the data-rich representation of explicit image pixels to a compact, semantic-rich representation of visually salient characteristics. In practice, the design of such primitives is non-trivial, and is driven by a number of conflicting real-world constraints (e.g. computation time vs. accuracy). The virage engine provides an open framework for developers to 'plug-in' primitives to solve specific image management problems. The architecture has been designed to support both static images and video in a unified paradigm. The infrastructure provided by the Virage engine can be utilized to address high-level problems as well, such as automatic, unsupervised keyword assignment, or image classification.

Essential issues in the design of shared document/image libraries  

NASA Astrophysics Data System (ADS)

We consider what is needed to create electronic document libraries which mimic physical collections of books, papers, and other media. The quantitative measures of merit for personal workstations-cost, speed, size of volatile and persistent storage-will improve by at least an order ofmagnitude in the next decade. Every professional worker will be able to afford a very powerful machine, but databases and libraries are not really economical and useful unless they are shared. We therefore see a two-tier world emerging, in which custodians of information make it available to network-attached workstations. A client-server model is the natural description of this world. In collaboration with several state governments, we have considered what would be needed to replace paper-based record management for a dozen different applications. We find that a professional worker can anticipate most data needs and that (s)he is interested in each clump of data for a period of days to months. We further find that only a small fraction of any collection will be used in any period. Given expected bandwidths, data sizes, search times and costs, and other such parameters, an effective strategy to support user interaction is to bring large clumps from their sources, to transform them into convenient representations, and only then start whatever investigation is intended. A system-managed hierarchy of caches and archives is indicated. Each library is a combination of a catalog and a collection, and each stored item has a primary instance which is the standard by which the correctness of any copy is judged. Catalog records mostly refer to 1 to 3 stored items. Weighted by the number of bytes to be stored, immutable data dominate collections. These characteristics affect how consistency, currency, and access control of replicas distributed in the network should be managed. We present the large features of a design for network docun1ent/image library services. A prototype is being built for State of California pilot applications. The design allows library servers in any environment with an ANSI SQL database; clients execute in any environment; conimunications are with either TCP/IP or SNA LU 6.2.

Image search based on quadtree Zernike decomposition  

NASA Astrophysics Data System (ADS)

A novel technique for searching for complex patterns in large multimedia databases is presented, based on rotation independent template matching. To handle objects of arbitrary shape while reducing the computational workload, the pattern to be localized is partitioned into small square blocks of sizes adapted to the local image content using quadtree decomposition. The use of Zernike polynomials for representing each block allows the design of a fast and effective maximum likelihood matching procedure to sequentially verify whether the target image contains each block of the quadtree. State of the art methods usually represent the whole pattern by using an orthogonal basis and extracting an invariant feature vector from the representation coefficients. In the proposed scheme, the use of the quadtree decomposition allows us to bind the number of terms of the truncated expansions, still guaranteeing a precise image representation.

Development and tuning of an original search engine for patent libraries in medicinal chemistry  

PubMed Central

Background The large increase in the size of patent collections has led to the need of efficient search strategies. But the development of advanced text-mining applications dedicated to patents of the biomedical field remains rare, in particular to address the needs of the pharmaceutical & biotech industry, which intensively uses patent libraries for competitive intelligence and drug development. Methods We describe here the development of an advanced retrieval engine to search information in patent collections in the field of medicinal chemistry. We investigate and combine different strategies and evaluate their respective impact on the performance of the search engine applied to various search tasks, which covers the putatively most frequent search behaviours of intellectual property officers in medical chemistry: 1) a prior art search task; 2) a technical survey task; and 3) a variant of the technical survey task, sometimes called known-item search task, where a single patent is targeted. Results The optimal tuning of our engine resulted in a top-precision of 6.76% for the prior art search task, 23.28% for the technical survey task and 46.02% for the variant of the technical survey task. We observed that co-citation boosting was an appropriate strategy to improve prior art search tasks, while IPC classification of queries was improving retrieval effectiveness for technical survey tasks. Surprisingly, the use of the full body of the patent was always detrimental for search effectiveness. It was also observed that normalizing biomedical entities using curated dictionaries had simply no impact on the search tasks we evaluate. The search engine was finally implemented as a web-application within Novartis Pharma. The application is briefly described in the report. Conclusions We have presented the development of a search engine dedicated to patent search, based on state of the art methods applied to patent corpora. We have shown that a proper tuning of the system to adapt to the various search tasks clearly increases the effectiveness of the system. We conclude that different search tasks demand different information retrieval engines' settings in order to yield optimal end-user retrieval. PMID:24564220

Optimization of reference library used in content-based medical image retrieval scheme  

SciTech Connect

Building an optimal image reference library is a critical step in developing the interactive computer-aided detection and diagnosis (I-CAD) systems of medical images using content-based image retrieval (CBIR) schemes. In this study, the authors conducted two experiments to investigate (1) the relationship between I-CAD performance and size of reference library and (2) a new reference selection strategy to optimize the library and improve I-CAD performance. The authors assembled a reference library that includes 3153 regions of interest (ROI) depicting either malignant masses (1592) or CAD-cued false-positive regions (1561) and an independent testing data set including 200 masses and 200 false-positive regions. A CBIR scheme using a distance-weighted K-nearest neighbor algorithm is applied to retrieve references that are considered similar to the testing sample from the library. The area under receiver operating characteristic curve (A{sub z}) is used as an index to evaluate the I-CAD performance. In the first experiment, the authors systematically increased reference library size and tested I-CAD performance. The result indicates that scheme performance improves initially from A{sub z}=0.715 to 0.874 and then plateaus when the library size reaches approximately half of its maximum capacity. In the second experiment, based on the hypothesis that a ROI should be removed if it performs poorly compared to a group of similar ROIs in a large and diverse reference library, the authors applied a new strategy to identify 'poorly effective' references. By removing 174 identified ROIs from the reference library, I-CAD performance significantly increases to A{sub z}=0.914 (p<0.01). The study demonstrates that increasing reference library size and removing poorly effective references can significantly improve I-CAD performance.

To assess the quality and usefulness of one health sciences library's mediated computer search service, a survey was undertaken to determine satisfaction rates, why users do or do not use the service, and how useful the service is perceived to be in comparison to instructional service. Satisfaction rates were high, with users indicating librarian expertise and time/cost savings as the main reasons for using the service. Non-users indicated that they preferred to do their own searching, and many were unaware of the service. Though a majority of respondents do not currently use the service, surprisingly a majority of respondents placed significant value on the mediated search service in relation to instruction.

Java Library for Input and Output of Image Data and Metadata  

NASA Technical Reports Server (NTRS)

A Java-language library supports input and output (I/O) of image data and metadata (label data) in the format of the Video Image Communication and Retrieval (VICAR) image-processing software and in several similar formats, including a subset of the Planetary Data System (PDS) image file format. The library does the following: It provides low-level, direct access layer, enabling an application subprogram to read and write specific image files, lines, or pixels, and manipulate metadata directly. Two coding/decoding subprograms ("codecs" for short) based on the Java Advanced Imaging (JAI) software provide access to VICAR and PDS images in a file-format-independent manner. The VICAR and PDS codecs enable any program that conforms to the specification of the JAI codec to use VICAR or PDS images automatically, without specific knowledge of the VICAR or PDS format. The library also includes Image I/O plugin subprograms for VICAR and PDS formats. Application programs that conform to the Image I/O specification of Java version 1.4 can utilize any image format for which such a plug-in subprogram exists, without specific knowledge of the format itself. Like the aforementioned codecs, the VICAR and PDS Image I/O plug-in subprograms support reading and writing of metadata.

Rochester Images  

NSDL National Science Digital Library

The Central Library of Rochester and Monroe County, New York offers this substantial database of photographs and other images, both historical and contemporary, that depict the Rochester area. Sponsored by a grant from the Institute for Museum and Library Services and funds from the federal government's Library Services and Technology Act, the site's goal is to demonstrate that electronic access to images can be a boon to scholars and researchers. The images themselves, some 22,000 of them, can either be browsed or searched by keyword, or users can search a specific field (author, title, subjects, etc.); search results include thumbnails that link to full-sized pictures. A helpful Search Tips page offers guidance on searching the images. Providing increased access to visual materials has proven to be one of the Web's successes for many libraries and archives, and this site is a good example of what can be accomplished through a well presented digitization project involving visual materials.

Searching for patterns in remote sensing image databases using neural networks  

NASA Technical Reports Server (NTRS)

We have investigated a method, based on a successful neural network multispectral image classification system, of searching for single patterns in remote sensing databases. While defining the pattern to search for and the feature to be used for that search (spectral, spatial, temporal, etc.) is challenging, a more difficult task is selecting competing patterns to train against the desired pattern. Schemes for competing pattern selection, including random selection and human interpreted selection, are discussed in the context of an example detection of dense urban areas in Landsat Thematic Mapper imagery. When applying the search to multiple images, a simple normalization method can alleviate the problem of inconsistent image calibration. Another potential problem, that of highly compressed data, was found to have a minimal effect on the ability to detect the desired pattern. The neural network algorithm has been implemented using the PVM (Parallel Virtual Machine) library and nearly-optimal speedups have been obtained that help alleviate the long process of searching through imagery.

Multiview alignment hashing for efficient image search.  

PubMed

Hashing is a popular and efficient method for nearest neighbor search in large-scale data spaces by embedding high-dimensional feature descriptors into a similarity preserving Hamming space with a low dimension. For most hashing methods, the performance of retrieval heavily depends on the choice of the high-dimensional feature descriptor. Furthermore, a single type of feature cannot be descriptive enough for different images when it is used for hashing. Thus, how to combine multiple representations for learning effective hashing functions is an imminent task. In this paper, we present a novel unsupervised multiview alignment hashing approach based on regularized kernel nonnegative matrix factorization, which can find a compact representation uncovering the hidden semantics and simultaneously respecting the joint probability distribution of data. In particular, we aim to seek a matrix factorization to effectively fuse the multiple information sources meanwhile discarding the feature redundancy. Since the raised problem is regarded as nonconvex and discrete, our objective function is then optimized via an alternate way with relaxation and converges to a locally optimal solution. After finding the low-dimensional representation, the hashing functions are finally obtained through multivariable logistic regression. The proposed method is systematically evaluated on three data sets: 1) Caltech-256; 2) CIFAR-10; and 3) CIFAR-20, and the results show that our method significantly outperforms the state-of-the-art multiview hashing techniques.

Searching for Pulsars Using Image Pattern Recognition  

NASA Astrophysics Data System (ADS)

In the modern era of big data, many fields of astronomy are generating huge volumes of data, the analysis of which can sometimes be the limiting factor in research. Fortunately, computer scientists have developed powerful data-mining techniques that can be applied to various fields. In this paper, we present a novel artificial intelligence (AI) program that identifies pulsars from recent surveys by using image pattern recognition with deep neural nets—the PICS (Pulsar Image-based Classification System) AI. The AI mimics human experts and distinguishes pulsars from noise and interference by looking for patterns from candidate plots. Different from other pulsar selection programs that search for expected patterns, the PICS AI is taught the salient features of different pulsars from a set of human-labeled candidates through machine learning. The training candidates are collected from the Pulsar Arecibo L-band Feed Array (PALFA) survey. The information from each pulsar candidate is synthesized in four diagnostic plots, which consist of image data with up to thousands of pixels. The AI takes these data from each candidate as its input and uses thousands of such candidates to train its ~9000 neurons. The deep neural networks in this AI system grant it superior ability to recognize various types of pulsars as well as their harmonic signals. The trained AI's performance has been validated with a large set of candidates from a different pulsar survey, the Green Bank North Celestial Cap survey. In this completely independent test, the PICS ranked 264 out of 277 pulsar-related candidates, including all 56 previously known pulsars and 208 of their harmonics, in the top 961 (1%) of 90,008 test candidates, missing only 13 harmonics. The first non-pulsar candidate appears at rank 187, following 45 pulsars and 141 harmonics. In other words, 100% of the pulsars were ranked in the top 1% of all candidates, while 80% were ranked higher than any noise or interference. The performance of this system can be improved over time as more training data are accumulated. This AI system has been integrated into the PALFA survey pipeline and has discovered six new pulsars to date.

Library of Virginia: Photographic Collections  

NSDL National Science Digital Library

The Library of Virginia's ongoing Digital Library Program in 2001 added eight public library digital photograph collections. Starting from the LVA Digital Library homepage, users select the name of one of the public library collections to go directly to its search page. For a little more information about the type of photographs to expect in each collection, we recommend beginning at the About the Collections page. Following this route, a user can learn that the digitized portion of the Hampton Public Library consists of 1,400 photographs from the Christopher E. Cheyne collection, including many downtown Hampton businesses, representing the seafood industry hotels and seaside resorts, and the amusement park. This collection also includes portraits of a few Civil War veterans, members of prominent Hampton families, and photographer Cheyne's family. In contrast, one would find fewer images of people in the Newport News Public Library collection, since it consists of close to 300 images related to the construction of Hilton Village, a World War I era public housing project, and the Hotel Warwick, a grand nineteenth-century resort. Searching is still a little unpredictable even with the additional information; to browse most of the images in a collection, try searching on a photographer's name, or the proper name of prominent subjects depicted.

Combined semantic and similarity search in medical image databases  

NASA Astrophysics Data System (ADS)

The current diagnostic process at hospitals is mainly based on reviewing and comparing images coming from multiple time points and modalities in order to monitor disease progression over a period of time. However, for ambiguous cases the radiologist deeply relies on reference literature or second opinion. Although there is a vast amount of acquired images stored in PACS systems which could be reused for decision support, these data sets suffer from weak search capabilities. Thus, we present a search methodology which enables the physician to fulfill intelligent search scenarios on medical image databases combining ontology-based semantic and appearance-based similarity search. It enabled the elimination of 12% of the top ten hits which would arise without taking the semantic context into account.

A 3D metal artifact correction method in cone-beam CT bone imaging by using an implant image library  

NASA Astrophysics Data System (ADS)

Cone-beam CT (CBCT) technique has been used by orthopedists to monitor bone graft growth after orthopedic surgery. In order to correct severe metal artifacts in reconstructed images caused by metal implants used in bone grafting, a three-dimensional metal artifact correction method has been previously proposed. The implants' mathematic boundaries were generated to help to segment metal from reconstructed images. The segmented metal implants were forward-projected onto the detector to create metal-only projections to compensate for beam-hardening effect. This method was proved effective with the metal implants of regular shape which can be simulated by simple 3D primitives, such as cuboid, cylinder and cone. But for metal implants of arbitrary shape, their boundaries are difficult to define mathematically. To solve this problem, this paper proposed a method by setting up an implant image library and using the implants' a priori shape information from the library during the artifact correction. The implants were acquired and scanned before the surgery and their a priori information were stored in a library. During the artifact correction, the library was called to provide the shape information of the implants to help to do the implant segmentation. The segmented implants were forward-projected onto the detector to generate implant-only projections by a cone-beam forward-projection technique. Beam-hardening effect in the original projections was then compensated by high polynomial orders of implant projections. Finally, the corrected projections were back-projected to produce artifacts-reduced images. Both phantom studies and patient studies were conducted to test this correction method. Results from both studies show the artifacts have been greatly reduced and the accuracy of bone volume measurement has been increased.

Facilitating Image Search With a Scalable and Compact Semantic Mapping.  

PubMed

This paper introduces a novel approach to facilitating image search based on a compact semantic embedding. A novel method is developed to explicitly map concepts and image contents into a unified latent semantic space for the representation of semantic concept prototypes. Then, a linear embedding matrix is learned that maps images into the semantic space, such that each image is closer to its relevant concept prototype than other prototypes. In our approach, the semantic concepts equated with query keywords and the images mapped into the vicinity of the prototype are retrieved by our scheme. In addition, a computationally efficient method is introduced to incorporate new semantic concept prototypes into the semantic space by updating the embedding matrix. This novelty improves the scalability of the method and allows it to be applied to dynamic image repositories. Therefore, the proposed approach not only narrows semantic gap but also supports an efficient image search process. We have carried out extensive experiments on various cross-modality image search tasks over three widely-used benchmark image datasets. Results demonstrate the superior effectiveness, efficiency, and scalability of our proposed approach. PMID:25248210

Image restoration using trellis-search methods  

NASA Astrophysics Data System (ADS)

Methods for the restoration of images corrupted by blur and noise are presented. During transmission through an optical or electrical channel, images become corrupted by blur and noise as a result of channel limitations (i.e. optical aberrations or a bandlimit). If images are treated as a matrix whose elements (pixels) assume a finite number of values then there is a large but finite set of possible images that can be transmitted. By treating this finite set as a `signal' set, digital communications methods may be used to estimate the uncorrupted image given a blurred and noisy version. Specifically, row-by-row estimation, decision-feedback and vector-quantization are used to extend the 1D sequence estimation ability of the a-posteriori probability (APP) and Viterbi algorithm (VA) to the estimation of 2D images. Simulations show the 2D VA and APP algorithms return near-optimal estimates of binary images as well as improved estimates of greyscale images when compared with the conventional Wiener filter (WF) estimates. Unlike the WF, the VA and APP algorithms are shown to be capable of super-resolution and adaptable for use with signal-dependent Poisson noise corruption. Restorations of experimental data gathered from an optical imaging system are presented to support simulation results.

An attribute-assisted reranking model for web image search.  

PubMed

Image search reranking is an effective approach to refine the text-based image search result. Most existing reranking approaches are based on low-level visual features. In this paper, we propose to exploit semantic attributes for image search reranking. Based on the classifiers for all the predefined attributes, each image is represented by an attribute feature consisting of the responses from these classifiers. A hypergraph is then used to model the relationship between images by integrating low-level visual features and attribute features. Hypergraph ranking is then performed to order the images. Its basic principle is that visually similar images should have similar ranking scores. In this paper, we propose a visual-attribute joint hypergraph learning approach to simultaneously explore two information sources. A hypergraph is constructed to model the relationship of all images. We conduct experiments on more than 1,000 queries in MSRA-MMV2.0 data set. The experimental results demonstrate the effectiveness of our approach. PMID:25420262

The visible ear: a digital image library of the temporal bone.  

PubMed

High-fidelity computer-based modeling, simulation and visualization systems for the study of temporal bone anatomy and training for middle ear surgery are based on a sequence of digital anatomical images, which must cover a large tissue volume and yet display details in high resolution and with high fidelity. However, the use of existing image libraries by independent developers of virtual models of the ear is limited by copyright protection and low image resolution. A fresh frozen human temporal bone was CT-scanned and serially sectioned at 25 microm and digital images of the block surface were recorded at 50- to 100-microm increments with a Light Phase(TM) single-shot camera back attachment. A total of 605 images were recorded in 24-bit RGB resolution. After color correction and elimination of image size variation by differential cropping to 15.4 cm x 9.7 cm, all images were resampled to 3,078 x 1,942 pixels at a final resolution of 50 microm/pixel and stored as 605 one-Mb JPEG files together with a three-dimensional viewer. The resulting complete set of image data provides: (1) a source material suitable for generating computer models of the human ear; (2) a resource of high-quality digital images of anatomical cross sections from the human ear, and (3) a PC-based viewer of the temporal bone in three perpendicular planes of section.

Imaging ATUM ultrathin section libraries with WaferMapper: a multi-scale approach to EM reconstruction of neural circuits  

PubMed Central

The automated tape-collecting ultramicrotome (ATUM) makes it possible to collect large numbers of ultrathin sections quickly—the equivalent of a petabyte of high resolution images each day. However, even high throughput image acquisition strategies generate images far more slowly (at present ~1 terabyte per day). We therefore developed WaferMapper, a software package that takes a multi-resolution approach to mapping and imaging select regions within a library of ultrathin sections. This automated method selects and directs imaging of corresponding regions within each section of an ultrathin section library (UTSL) that may contain many thousands of sections. Using WaferMapper, it is possible to map thousands of tissue sections at low resolution and target multiple points of interest for high resolution imaging based on anatomical landmarks. The program can also be used to expand previously imaged regions, acquire data under different imaging conditions, or re-image after additional tissue treatments. PMID:25018701

Designing Novel Image Search Interfaces by Understanding Unique Characteristics and Usage  

NASA Astrophysics Data System (ADS)

In most major search engines, the interface for image search is the same as traditional Web search: a keyword query followed by a paginated, ranked list of results. Although many image search innovations have appeared in both the literature and on the Web, few have seen widespread use in practice. In this work, we explore the differences between image and general Web search to better support users’ needs. First, we describe some unique characteristics of image search derived through informal interviews with researchers, designers, and managers responsible for building and deploying a major Web search engine. Then, we present results from a large scale analysis of image and Web search logs showing the differences in user behaviour. Grounded in these observations, we present design recommendations for an image search engine supportive of the unique experience of image search. We iterate on a number of designs, and describe a functional prototype that we built.

Finding corners in images by foveated search  

NASA Astrophysics Data System (ADS)

We develop a new approach to finding corners in images that combines foveated edge detection and curvature calculation with saccadic placement of foveal fixations. Each saccade moves the fovea to a location of high curvature combined with high edge gradient. Edges are located using a foveated Canny edge detector with spatial constant that increases with eccentricity. Next, we calculate a measure of local corner strength, based on a product of curvature and gradient. An inhibition factor based on previous visits to a region of the image prevents the system from repeatedly returning to the same locale. A long saccade is move thes fovea to previously unexplored areas of the image. Subsequent short saccades improve the accuracy of the location of the corner approximated by the long saccade. The system is tested on two natural scenes and the results compared against subjects observing the same test images through an eyetracker. Results show that the algorithm is a good locator of corners.

Search and detection modeling of military imaging systems  

NASA Astrophysics Data System (ADS)

For more than 50 years, the U.S. Army RDECOM CERDEC Night Vision and Electronic Sensors Directorate (NVESD) has been studying the science behind the human processes of searching and detecting, and using that knowledge to develop and refine its models for military imaging systems. Modeling how human observers perform military tasks while using imaging systems in the field and linking that model with the physics of the systems has resulted in the comprehensive sensor models we have today. These models are used by the government, military, industry, and academia for sensor development, sensor system acquisition, military tactics development, and war-gaming. From the original hypothesis put forth by John Johnson in 1958, to modeling time-limited search, to modeling the impact of motion on target detection, to modeling target acquisition performance in different spectral bands, the concept of search has a wide-ranging history. Our purpose is to present a snapshot of that history; as such, it will begin with a description of the search-modeling task, followed by a summary of highlights from the early years, and concluding with a discussion of search and detection modeling today and the changing battlefield. Some of the topics to be discussed will be classic search, clutter, computational vision models and the ACQUIRE model with its variants. We do not claim to present a complete history here, but rather a look at some of the work that has been done, and this is meant to be an introduction to an extensive amount of work on a complex topic. That said, it is hoped that this overview of the history of search and detection modeling of military imaging systems pursued by NVESD directly, or in association with other government agencies or contractors, will provide both the novice and experienced search modeler with a useful historical summary and an introduction to current issues and future challenges.

Rebels in search of champions: Envisioning the library of the future  

SciTech Connect

The traditional role of librarians to secure and provide access to the archives of recorded knowledge is being rapidly challenged on three fronts: the increasing technical sophistication of library users, the wide availability of information management software, and economic pressures on the growth of library collections. While we may argue endlessly about turf'' and ownership'', the real challenge is to forge a new ethic of librarianship which defies the stereotype of the passive provider of information services, explores new models of partnership with users, and champions an interactive environment in which to create the library of the future. The Main Library at Lawrence Livermore National Laboratory is actively engaged in testing experimental models of the library of the future, centered on dynamic user-librarian interactions, versatile information technologies, and on forecasting creative partnerships with library users in different environments. These experiments are described, evaluated, and their implications for future development are explored. 39 refs.

Adapted waveform analysis, wavelet packets, and local cosine libraries as a tool for image processing  

NASA Astrophysics Data System (ADS)

Adapted wave form analysis, refers to a collection of FFT like adapted transform algorithms. Given an image these methods provide special matched collections of templates (orthonormal bases) enabling an efficient coding of the image. Perhaps the closest well known examples of such coding method is provided by musical notation, where each segment of music is represented by a musical score made up of notes (templates) characterized by their duration, pitch, location and amplitude, our method corresponds to transcribing the music in as few notes as possible. The extension of images and video is straightforward. We describe the image by collections of oscillatory patterns of various sizes, locations and amplitudes using a variety of orthogonal bases. These selected basis functions are chosen inside predefined libraries of oscillatory localized functions (trigonometric and wavelet-packets waveforms) so as to optimize the number of parameters needed to describe our object. These algorithms are of complexity N log N opening the door for a large range of applications in signal and image processing, such as compression, feature extraction denoising and enhancement. In particular we describe a class of special purpose compressions for fingerprint images, as well as denoising tools for texture and noise extraction.

Searching for pulsars using image pattern recognition  

E-print Network

In this paper, we present a novel artificial intelligence (AI) program that identifies pulsars from recent surv eys using image pattern recognition with deep neural nets---the PICS(Pulsar Image-based Classification System) AI. The AI mimics human experts and distinguishes pulsars from noise and interferences by looking for patterns from candidate. The information from each pulsar candidate is synthesized in four diagnostic plots, which consist of up to thousands pixel of image data. The AI takes these data from each candidate as its input and uses thousands of such candidates to train its $\\sim$9000 neurons. Different from other pulsar selection programs which use pre-designed patterns, the PICS AI teaches itself the salient features of different pulsars from a set of human-labeled candidates through machine learning. The deep neural networks in this AI system grant it superior ability in recognizing various types of pulsars as well as their harmonic signals. The trained AI's performance has been validated wi...

On-line literature searching: comparison of PaperChase and National Library of Medicine data bases.  

PubMed

Two computerized retrieval systems--the National Library of Medicine (NLM) data bases (MEDLINE, TOXLINE, and their respective backfiles) and PaperChase (PC), a subset of the NLM data base, were compared. Comparative parameters of retrieval and costs for literature searching performed on each system were evaluated. Objective measures were used in the evaluation, as well as a subjective assessment of user satisfaction with each system. Data indicate that NLM is a faster and more direct search procedure for a trained individual, making it a more favorable choice in a drug information center. PC is a valuable tool for sites requiring or offering on-line access to many different people searching infrequently. Because P & T Committees must have access to comprehensive and timely literature, knowledge of various retrieval systems is beneficial. PMID:10301284

Oriented modulation for watermarking in direct binary search halftone images.  

PubMed

In this paper, a halftoning-based watermarking method is presented. This method enables high pixel-depth watermark embedding, while maintaining high image quality. This technique is capable of embedding watermarks with pixel depths up to 3 bits without causing prominent degradation to the image quality. To achieve high image quality, the parallel oriented high-efficient direct binary search (DBS) halftoning is selected to be integrated with the proposed orientation modulation (OM) method. The OM method utilizes different halftone texture orientations to carry different watermark data. In the decoder, the least-mean-square-trained filters are applied for feature extraction from watermarked images in the frequency domain, and the naïve Bayes classifier is used to analyze the extracted features and ultimately to decode the watermark data. Experimental results show that the DBS-based OM encoding method maintains a high degree of image quality and realizes the processing efficiency and robustness to be adapted in printing applications.

Searching for the limit of image quality in film radiography  

SciTech Connect

Radiographic film image quality in general was, and in most cases still is, considered as a very subjective and rather vague parameter. Yet it is of vital importance to the NDT and related quality control and quality assurance industry. Therefore, lately Agfa has put a major effort into quantifying image quality in an objective, measurable way. It was in the framework of this optimization project, that the authors, based on these new insights in imaging of industrial film systems, strived to search for the limit of the highest achievable image quality. In this paper they report these results. They not only report these results in an academic way, meaning how this highest image quality can be achieved under lab conditions, but also how these same results can be obtained under practical e.g. field-conditions.

SimITK: visual programming of the ITK image-processing library within Simulink.  

PubMed

The Insight Segmentation and Registration Toolkit (ITK) is a software library used for image analysis, visualization, and image-guided surgery applications. ITK is a collection of C++ classes that poses the challenge of a steep learning curve should the user not have appropriate C++ programming experience. To remove the programming complexities and facilitate rapid prototyping, an implementation of ITK within a higher-level visual programming environment is presented: SimITK. ITK functionalities are automatically wrapped into "blocks" within Simulink, the visual programming environment of MATLAB, where these blocks can be connected to form workflows: visual schematics that closely represent the structure of a C++ program. The heavily templated C++ nature of ITK does not facilitate direct interaction between Simulink and ITK; an intermediary is required to convert respective data types and allow intercommunication. As such, a SimITK "Virtual Block" has been developed that serves as a wrapper around an ITK class which is capable of resolving the ITK data types to native Simulink data types. Part of the challenge surrounding this implementation involves automatically capturing and storing the pertinent class information that need to be refined from an initial state prior to being reflected within the final block representation. The primary result from the SimITK wrapping procedure is multiple Simulink block libraries. From these libraries, blocks are selected and interconnected to demonstrate two examples: a 3D segmentation workflow and a 3D multimodal registration workflow. Compared to their pure-code equivalents, the workflows highlight ITK usability through an alternative visual interpretation of the code that abstracts away potentially confusing technicalities.

A search of outer Trojans on ASTROVIRTEL images  

NASA Astrophysics Data System (ADS)

This paper discusses the main results of a search of outer Trojans on ESO/ESA ASTROVIRTEL images, and the usefulness and the limitations of such an archive for the discovery and dynamical classification of minor bodies. The work was performed in the frame of a program having the aim to detect bodies orbiting around the Lagrangian points of the outer planets. A large number of images taken from 1999 to 2001 with the wide field imager (WFI) camera of the 2.2 m telescope of ESO at La Silla for entirely different scientific reasons, but happening to be in the wanted Lagrangian positions, was retrieved with a dedicated search engine. The moving objects present on these images were detected and examined with specific software tools that permitted one to find out about 1500 minor bodies (mostly previously unknown). More than 5000 positions were sent to the Minor Planet Center, and the search was given the designation I03. The total sky area covered by I03 is of approximately 50 square degrees, and in some areas the limiting magnitudes were fainter than the 24th in the R band. A preliminary classification of the kinematics of the I03 discoveries (using a dedicated code, named AMIGO apparent motion interpretation of generic orbits) has produced several Trojan candidates of Jupiter and of the outer planets. Furthermore, pre-discovery positions have been provided for one NEO, three Jupiter Trojans and three TNOs.

The extension to images and video is straightforward we describe the image by collections of oscillatory patterns (paint brush strokes)of various sizes locations and amplitudes using a variety of orthogonal bases. These selected basis functions are chosen inside predefined libraries of oscillatory localized functions (trigonometric and wavelet-packets waveforms) so as to optimize the number of parameters needed to describe our object. These algorithms are of complexity N log N opening the door for a large range of applications in signal and image processing, such as compression, feature extraction denoising and enhancement. In particular we describe a class of special purpose compressions for fingerprint irnages, as well as denoising tools for texture and noise extraction. We start by relating traditional Fourier methods to wavelet, wavelet-packet based algorithms using a recent refinement of the windowed sine and cosine transforms. We will then derive an adapted local sine transform show it's relation to wavelet and wavelet-packet analysis and describe an analysis toolkit illustrating the merits of different adaptive and nonadaptive schemes.

HSI-Find: A Visualization and Search Service for Terascale Spectral Image Catalogs  

NASA Astrophysics Data System (ADS)

Imaging spectrometers are remote sensing instruments commonly deployed on aircraft and spacecraft. They provide surface reflectance in hundreds of wavelength channels, creating data cubes known as hyperspecrtral images. They provide rich compositional information making them powerful tools for planetary and terrestrial science. These data products can be challenging to interpret because they contain datapoints numbering in the thousands (Dawn VIR) or millions (AVIRIS-C). Cross-image studies or exploratory searches involving more than one scene are rare; data volumes are often tens of GB per image and typical consumer-grade computers cannot store more than a handful of images in RAM. Visualizing the information in a single scene is challenging since the human eye can only distinguish three color channels out of the hundreds available. To date, analysis has been performed mostly on single images using purpose-built software tools that require extensive training and commercial licenses. The HSIFind software suite provides a scalable distributed solution to the problem of visualizing and searching large catalogs of spectral image data. It consists of a RESTful web service that communicates to a javascript-based browser client. The software provides basic visualization through an intuitive visual interface, allowing users with minimal training to explore the images or view selected spectra. Users can accumulate a library of spectra from one or more images and use these to search for similar materials. The result appears as an intensity map showing the extent of a spectral feature in a scene. Continuum removal can isolate diagnostic absorption features. The server-side mapping algorithm uses an efficient matched filter algorithm that can process a megapixel image cube in just a few seconds. This enables real-time interaction, leading to a new way of interacting with the data: the user can launch a search with a single mouse click and see the resulting map in seconds. This allows the user to quickly explore each image, ascertain the main units of surface material, localize outliers, and develop an understanding of the various materials' spectral characteristics. The HSIFind software suite is currently in beta testing at the Planetary Science Institute and a process is underway to release it under an open source license to the broader community. We believe it will benefit instrument operations during remote planetary exploration, where tactical mission decisions demand rapid analysis of each new dataset. The approach also holds potential for public spectral catalogs where its shallow learning curve and portability can make these datasets accessible to a much wider range of researchers.

Managing biomedical image metadata for search and retrieval of similar images.  

PubMed

Radiology images are generally disconnected from the metadata describing their contents, such as imaging observations ("semantic" metadata), which are usually described in text reports that are not directly linked to the images. We developed a system, the Biomedical Image Metadata Manager (BIMM) to (1) address the problem of managing biomedical image metadata and (2) facilitate the retrieval of similar images using semantic feature metadata. Our approach allows radiologists, researchers, and students to take advantage of the vast and growing repositories of medical image data by explicitly linking images to their associated metadata in a relational database that is globally accessible through a Web application. BIMM receives input in the form of standard-based metadata files using Web service and parses and stores the metadata in a relational database allowing efficient data query and maintenance capabilities. Upon querying BIMM for images, 2D regions of interest (ROIs) stored as metadata are automatically rendered onto preview images included in search results. The system's "match observations" function retrieves images with similar ROIs based on specific semantic features describing imaging observation characteristics (IOCs). We demonstrate that the system, using IOCs alone, can accurately retrieve images with diagnoses matching the query images, and we evaluate its performance on a set of annotated liver lesion images. BIMM has several potential applications, e.g., computer-aided detection and diagnosis, content-based image retrieval, automating medical analysis protocols, and gathering population statistics like disease prevalences. The system provides a framework for decision support systems, potentially improving their diagnostic accuracy and selection of appropriate therapies. PMID:20844917

Bad Pixels, Cosmic Rays, and PSF-libraries from deep HST/WFC images  

NASA Astrophysics Data System (ADS)

We present the careful removal of bad pixels and cosmic-ray (``CR'') events from HST/WFC images. The WFC bad-pixel map is known to vary with time, because the intense on-orbit CR-flux (see below) increases the dark-current of pixels that have been hit by CR's many times. This is not always properly reflected in the standard WFC dark-frames. We have thus begun a program to monitor and update ``new'' WFC bad pixels over time. Similarly, we present the construction of a library of PSF-stars from available Cycle 1 images across the WFC field-of-view in various filters. This will allow us to monitor the PSF's time- and focus-dependence, and to properly deconvolve objects seen in sub-sections of WFC images with no available nearby PSF-star (see our other HST AAS-posters this Volume). To assess the on-orbit cosmic-ray flux quantitatively, we constructed CR-clipped images from our 8---12 orbit WFC data-cube through an iterative local 2sigma -clip that uses and preserves the local S/N per pixel, and subtracted these from the straight image average. The resulting ``CR-images'' were processed with FOCAS using various detection thresholds. Differential CR ``magnitude-counts'' follow from their summed DN/unit time (as if all CR's had been misclassified as objects). The CR-``counts'' have a power-law slope gamma =~ 0.60 [N(m)~ m(gamma ) ]. At Gunn g=25 mag, the CR-``counts'' are ~ 1.0 dex higher in amplitude than the galaxy counts. They continue with a nearly ``Euclidean'' slope down to g=27.5 mag (our 1-sigma point source sensitivity), below which they turnover due to ``incompleteness'' and FOCAS splitting problems. Their formal sky-integral thus ``diverges'' into the noise, and their integral surface density approaches ~ 10(8) \\ deg(-2) down to g=28 mag, which corresponds to 1 out of every 12 pixels in the WFC data-cube, or an integrated sky-signal of at least V =~ 25.0--25.75 mag/arcsec(-2) . This work was supported by NASA/HST grants GO-2405-01-87A from STScI, which is operated by AURA, Inc., under NASA contract NAS5-26555, and by the Alfred P. Sloan Foundation.

Protocols for printing thick film ceramic libraries using the London University Search Instrument (LUSI)  

SciTech Connect

Thick film combinatorial libraries can be prepared by mixing ceramic suspensions using stepper-driven syringes to control ink-jet-printing nozzles, but a more tolerant and efficient method has been devised using a simplification of the same equipment. By simplifying the printing sequence and using direct deposition from the stepper syringes, the time committed to a repetitive sequence of priming and cleaning the ink-jet printer nozzles is reduced. Polytetrafluoroethylene (PTFE) open ended tubes and commercial pipette tips are used as the printing nozzles. Calibration and corrections for the method are described. This method opens up the possibility for making ceramic libraries more rapidly with much simpler and less expensive equipment.

Index of Medieval Medical Images  

NSDL National Science Digital Library

Images from medieval medical manuscripts held by major libraries - including the National Library of Medicine, Rosenbach Museum and Library, University of California, Los Angeles (UCLA), University of Vermont, and Yale University - make up the Index of Medieval Medical Images. The indexing project began in 1988, and in 2001, a pilot project was started to digitize about 500 images and make them available online. To start, click on "Search Images". We found browsing to be the most productive way to begin searching, as it makes it possible to select search terms such as subject and image type, date and country of origin. Once familiar with the database, keyword and advanced searches are also fruitful. Another useful tool "My Virtual Collection" allows users to add notes to images and save them - creating their own collection, users can then choose to email their personal collection to themselves, students, or colleagues.

A new image stabilization algorithm based on improved diamond search combined with adaptive partitioning optimization  

NASA Astrophysics Data System (ADS)

Since the traditional block matching method in the larger search window tend to fall into local optimum to be unsuitable solving large pan shake image stabilization problem, a new image stabilization algorithm is proposed, which is still based on diamond search, but the pattern of large template is modified to ring, search domain is partitioned and sorted by size, global motion vector is extracted through maximum sample statistics and compensated through adaptive mean filter. A numerical example is calculated to show that the method has a higher search efficiency than exhaustive search, three-step search, four-step search and traditional diamond search; maximum sample statistics avoid the prospect's interference effectively when global motion vectors is extracted; adaptive filter compensation has better real-time and smoothness than a fixed size one; PSNR of images after processed is higher significantly than the one before processed. Therefore the results above verify the accuracy of the algorithm and feasibility.

The search for new amphiphiles: synthesis of a modular, high-throughput library.  

PubMed

Amphiphilic compounds are used in a variety of applications due to their lyotropic liquid-crystalline phase formation, however only a limited number of compounds, in a potentially limitless field, are currently in use. A library of organic amphiphilic compounds was synthesised consisting of glucose, galactose, lactose, xylose and mannose head groups and double and triple-chain hydrophobic tails. A modular, high-throughput approach was developed, whereby head and tail components were conjugated using the copper-catalysed azide-alkyne cycloaddition (CuAAC) reaction. The tails were synthesised from two core alkyne-tethered intermediates, which were subsequently functionalised with hydrocarbon chains varying in length and degree of unsaturation and branching, while the five sugar head groups were selected with ranging substitution patterns and anomeric linkages. A library of 80 amphiphiles was subsequently produced, using a 24-vial array, with the majority formed in very good to excellent yields. A preliminary assessment of the liquid-crystalline phase behaviour is also presented. PMID:25161714

Efficient substructure searching of large chemical libraries: the ABCD chemical cartridge.  

PubMed

Efficient substructure searching is a key requirement for any chemical information management system. In this paper, we describe the substructure search capabilities of ABCD, an integrated drug discovery informatics platform developed at Johnson & Johnson Pharmaceutical Research & Development, L.L.C. The solution consists of several algorithmic components: 1) a pattern mapping algorithm for solving the subgraph isomorphism problem, 2) an indexing scheme that enables very fast substructure searches on large structure files, 3) the incorporation of that indexing scheme into an Oracle cartridge to enable querying large relational databases through SQL, and 4) a cost estimation scheme that allows the Oracle cost-based optimizer to generate a good execution plan when a substructure search is combined with additional constraints in a single SQL query. The algorithm was tested on a public database comprising nearly 1 million molecules using 4,629 substructure queries, the vast majority of which were submitted by discovery scientists over the last 2.5 years of user acceptance testing of ABCD. 80.7% of these queries were completed in less than a second and 96.8% in less than ten seconds on a single CPU, while on eight processing cores these numbers increased to 93.2% and 99.7%, respectively. The slower queries involved extremely generic patterns that returned the entire database as screening hits and required extensive atom-by-atom verification. PMID:22035187

SearchSmallRNA: a graphical interface tool for the assemblage of viral genomes using small RNA libraries data  

PubMed Central

Background Next-generation parallel sequencing (NGS) allows the identification of viral pathogens by sequencing the small RNAs of infected hosts. Thus, viral genomes may be assembled from host immune response products without prior virus enrichment, amplification or purification. However, mapping of the vast information obtained presents a bioinformatics challenge. Methods In order to by pass the need of line command and basic bioinformatics knowledge, we develop a mapping software with a graphical interface to the assemblage of viral genomes from small RNA dataset obtained by NGS. SearchSmallRNA was developed in JAVA language version 7 using NetBeans IDE 7.1 software. The program also allows the analysis of the viral small interfering RNAs (vsRNAs) profile; providing an overview of the size distribution and other features of the vsRNAs produced in infected cells. Results The program performs comparisons between each read sequenced present in a library and a chosen reference genome. Reads showing Hamming distances smaller or equal to an allowed mismatched will be selected as positives and used to the assemblage of a long nucleotide genome sequence. In order to validate the software, distinct analysis using NGS dataset obtained from HIV and two plant viruses were used to reconstruct viral whole genomes. Conclusions SearchSmallRNA program was able to reconstructed viral genomes using NGS of small RNA dataset with high degree of reliability so it will be a valuable tool for viruses sequencing and discovery. It is accessible and free to all research communities and has the advantage to have an easy-to-use graphical interface.

A geometry-based image search engine for advanced RADARSAT-1/2 GIS applications  

NASA Astrophysics Data System (ADS)

Space-borne Synthetic Aperture Radar (SAR) sensors, such as RADARSAT-1 and -2, enable a multitude of defense and security applications owing to their unique capabilities of cloud penetration, day/night imaging and multi-polarization imaging. As a result, advanced SAR image time series exploitation techniques such as Interferometric SAR (InSAR) and Radargrammetry are now routinely used in applications such as underground tunnel monitoring, infrastructure monitoring and DEM generation. Imaging geometry, as determined by the satellite orbit and imaged terrain, plays a critical role in the success of such techniques. This paper describes the architecture and the current status of development of a geometry-based search engine that allows the search and visualization of archived and future RADARSAT-1 and -2 images appropriate for a variety of advanced SAR techniques and applications. Key features of the search engine's scalable architecture include (a) Interactive GIS-based visualization of the search results; (b) A client-server architecture for online access that produces up-to-date searches of the archive images and that can, in future, be extended to acquisition planning; (c) A techniquespecific search mode, wherein an expert user explicitly sets search parameters to find appropriate images for advanced SAR techniques such as InSAR and Radargrammetry; (d) A future application-specific search mode, wherein all search parameters implicitly default to preset values according to the application of choice such as tunnel monitoring, DEM generation and deformation mapping; (f) Accurate baseline calculations for InSAR searches, and, optimum beam configuration for Radargrammetric searches; (g) Simulated quick look images and technique-specific sensitivity maps in the future.

Methane Imaging Search for Planetary Mass Objects in Rho Ophiuchi  

NASA Astrophysics Data System (ADS)

Outside our solar system, T dwarfs have the coldest photospheres that are currently accessible to direct observation. With masses inferred to lie between 10 and 60 times that of Jupiter, these objects represent a class of object linking the properties of observable low mass stars and brown dwarfs with those of unobservable extrasolar planets. Because of their low photospheric temperatures, an understanding of the atmospheres of T dwarfs is likely to yield important clues about the nature of giant planetary atmospheres. The cool atmospheres of T dwarfs are rich in molecular gases, especially methane (CH4). In fact, strong, broad CH4 absorption lines at near-infrared wavelengths represent the distinguishing feature of T dwarfs from hotter objects. Most T dwarfs have been discovered in large area sky surveys, however recently astronomers have begun searching for T dwarfs in young star clusters. Surveying young clusters has several advantages. First, low mass objects are more luminous at this stage of their evolution than those in the field. In addition, objects in clusters have well known ages, as opposed to field objects for which the ages are extremely difficult to determine. Finally, as T dwarfs are 2-5 orders of magnitude brighter when young, it allows them to be detected at greater distance. For these reasons, we have recently conducted a CH4 imaging survey of the Rho Ophiuchi cluster for T dwarfs using the IRIS2 imager on the Anglo Australian Telescope. The Rho Ophiuchi cloud is the closest (d 120 parsecs) star-forming region to Earth that has a compact core harboring several hundred young ( 1 Myr) stellar objects. In this poster, we present the results of our imaging survey.

Qualitative Confirmation of 9 Synthetic Cannabinoids and 20 Metabolites in Human Urine Using LC–MS/MS and Library Search  

PubMed Central

Introduction Synthetic cannabinoids are an emerging illicit drug class. The variety of available substances is large and ever-changing, making it difficult for laboratories to remain current. We present a qualitative LC–MS/MS method identifying urinary metabolites of JWH-018, JWH-073, JWH-081, JWH-122, JWH-200, JWH-210, JWH-250, RCS-4, and AM2201 and the parent compounds JWH-018, JWH-073, JWH-081, JWH-122, JWH-210, JWH-250, RCS-4, AM2201, and MAM2201. Methods After enzymatic hydrolysis, urinary proteins were precipitated with acetonitrile. Chromatography utilized a 10 min gradient on a Kinetex XB-C18 column with 0.1% formic acid in water and acetonitrile. Scheduled multiple reaction monitoring “survey scans” were followed by information-dependent acquisition-enhanced product ion scan experiments on an ABSciex 5500 QTRAP mass spectrometer. Analytes were identified by software-assisted library searching against reference spectra. Results The method was fully validated, including proof of selectivity (no exogenous or endogenous interferences were observed), assessment of matrix effects (95–122%) and recovery (53–95%), determination of limits of detection (0.5–10 ng/mL), carry-over studies (thresholds between 100 and 1000 ng/mL), and determination of autosampler stability (samples were stable for at least 3 days). Hydrolysis efficiency was thoroughly investigated for a wide range of glucuronides and for the reference standard, JWH-018 5-hydroxypentyl glucuronide PMID:23458260

Towards better digital pathology workflows: programming libraries for high-speed sharpness assessment of Whole Slide Images  

PubMed Central

Background Since microscopic slides can now be automatically digitized and integrated in the clinical workflow, quality assessment of Whole Slide Images (WSI) has become a crucial issue. We present a no-reference quality assessment method that has been thoroughly tested since 2010 and is under implementation in multiple sites, both public university-hospitals and private entities. It is part of the FlexMIm R&D project which aims to improve the global workflow of digital pathology. For these uses, we have developed two programming libraries, in Java and Python, which can be integrated in various types of WSI acquisition systems, viewers and image analysis tools. Methods Development and testing have been carried out on a MacBook Pro i7 and on a bi-Xeon 2.7GHz server. Libraries implementing the blur assessment method have been developed in Java, Python, PHP5 and MySQL5. For web applications, JavaScript, Ajax, JSON and Sockets were also used, as well as the Google Maps API. Aperio SVS files were converted into the Google Maps format using VIPS and Openslide libraries. Results We designed the Java library as a Service Provider Interface (SPI), extendable by third parties. Analysis is computed in real-time (3 billion pixels per minute). Tests were made on 5000 single images, 200 NDPI WSI, 100 Aperio SVS WSI converted to the Google Maps format. Conclusions Applications based on our method and libraries can be used upstream, as calibration and quality control tool for the WSI acquisition systems, or as tools to reacquire tiles while the WSI is being scanned. They can also be used downstream to reacquire the complete slides that are below the quality threshold for surgical pathology analysis. WSI may also be displayed in a smarter way by sending and displaying the regions of highest quality before other regions. Such quality assessment scores could be integrated as WSI's metadata shared in clinical, research or teaching contexts, for a more efficient medical informatics workflow. PMID:25565494

Contextual hashing for large-scale image search.  

PubMed

With the explosive growth of the multimedia data on the Web, content-based image search has attracted considerable attentions in the multimedia and the computer vision community. The most popular approach is based on the bag-of-visual-words model with invariant local features. Since the spatial context information among local features is critical for visual content identification, many methods exploit the geometric clues of local features, including the location, the scale, and the orientation, for explicitly post-geometric verification. However, usually only a few initially top-ranked results are geometrically verified, considering the high computational cost in full geometric verification. In this paper, we propose to represent the spatial context of local features into binary codes, and implicitly achieve geometric verification by efficient comparison of the binary codes. Besides, we explore the multimode property of local features to further boost the retrieval performance. Experiments on holidays, Paris, and Oxford building benchmark data sets demonstrate the effectiveness of the proposed algorithm. PMID:24577195

Molecule-specific imaging with mass spectrometry and a buckminsterfullerene probe: application to characterizing solid-phase synthesized combinatorial libraries.  

PubMed

We employ a newly developed buckminsterfullerene (C(60)) primary ion beam with time-of-flight secondary ion mass spectrometry to create molecule-specific images of resin particles employed in the solid-phase synthesis of peptide combinatorial libraries. This new cluster ion source, when operated at an incident energy of 20 keV, is remarkably effective at desorbing small peptides directly from a polymer surface and opens new possibilities for characterizing large arrays of diverse sets of molecules. In addition, the C(60) ion beam may be focused to a spot of 1.5 microm in diameter, enabling molecule-specific images of single 100 microm resin particles to be acquired. We report three significant aspects associated with utilizing the C(60) projectile that show how this technology can be taken to a more advanced level, especially when compared to results obtained with more conventional atomic primary ions. First, the useful yield of molecular ions is generally observed to be enhanced by at least 3 orders of magnitude over those previously possible. Second, the energy dissipation process associated with the C(60) impact is most efficient at desorbing molecules on soft substrates such as polymer surfaces rather than harder substrates such as metals or semiconductors. Third, there is a greatly reduced tendency for insulating surfaces to build up excess charge, obviating the need for charge compensation. Using a small five-member peptide library as a model, we show that by utilizing the focusing properties of the C(60) beam, it is possible to assay the surface composition of 100-microm polymer beads at a rate of up to 10 particles/s. Moreover, even at the picomole level, there are enough sequence ions in the mass spectrum to determine a unique composition. The results illustrate the ability to quickly assay large libraries without the use of tags and suggest the strategy may be applicable to a range of high-throughput experiments. PMID:15038744

Detection and identification of 700 drugs by multi-target screening with a 3200 Q TRAP LC-MS/MS system and library searching.  

PubMed

The multi-target screening method described in this work allows the simultaneous detection and identification of 700 drugs and metabolites in biological fluids using a hybrid triple-quadrupole linear ion trap mass spectrometer in a single analytical run. After standardization of the method, the retention times of 700 compounds were determined and transitions for each compound were selected by a "scheduled" survey MRM scan, followed by an information-dependent acquisition using the sensitive enhanced product ion scan of a Q TRAP hybrid instrument. The identification of the compounds in the samples analyzed was accomplished by searching the tandem mass spectrometry (MS/MS) spectra against the library we developed, which contains electrospray ionization-MS/MS spectra of over 1,250 compounds. The multi-target screening method together with the library was included in a software program for routine screening and quantitation to achieve automated acquisition and library searching. With the help of this software application, the time for evaluation and interpretation of the results could be drastically reduced. This new multi-target screening method has been successfully applied for the analysis of postmortem and traffic offense samples as well as proficiency testing, and complements screening with immunoassays, gas chromatography-mass spectrometry, and liquid chromatography-diode-array detection. Other possible applications are analysis in clinical toxicology (for intoxication cases), in psychiatry (antidepressants and other psychoactive drugs), and in forensic toxicology (drugs and driving, workplace drug testing, oral fluid analysis, drug-facilitated sexual assault).

Fermilab Library projects  

SciTech Connect

Preprint database management as done at various centers -- the subject of this workshop -- is hard to separate from the overall activities of the particular center. We therefore present the wider context at the Fermilab Library into which preprint database management fits. The day-to-day activities of the Library aside, the dominant activity at present is that of the ongoing Fermilab Library Automation. A less dominant but relatively time-consuming activity is that of doing more online searches in commercial databases on behalf of laboratory staff and visitors. A related activity is that of exploring the benefits of end-user searching of similar sources as opposed to library staff searching of the same. The Library Automation Project, which began about two years ago, is about to go fully online.'' The rationale behind this project is described in the documents developed during the December 1988--February 1989 planning phase.

The impact of complaint management and service quality on organizational image: A case study at the Malaysian public university library  

NASA Astrophysics Data System (ADS)

Service failure frequently occurs. This affects customer expectations which lead to complaint. However, not all dissatisfied customers actually complain. Without customer feedback, it would be impossible for a company to know whether they needed a change for improvement. Thus, complaint management brings a learning experience to organization in order to provide better service. Therefore, it is important to identify customer dissatisfaction through a systematic complaint handling or management. The study proposes a model of systematic complaint management which applied to academic library as a tool of service recovery. As such, the main purpose of this study is to investigate the critical success factors of complaint management towards service quality, customer satisfaction, customer loyalty and the impact to organizational image at academic library. Three academic libraries have been identified and selected for this project, the Library of Tun Sri Lanang, UKM, UTeM and UNIMAS. Using the justice theory, this study investigates the perception of customers on complaint management in terms of outcomes they receive, procedures used by organization and interpersonal treatment. In this study, there are five factors of complaint management identified, which includes speed of recovery, management system, empowerment, culture and psychology and tangible compensation. A questionnaire was designed and used as the data gathering instrument. A total of 600 respondents participated in this study. Ten hypotheses were used to test the relationships between complaint management, service quality, customer satisfaction, customer loyalty and organizational image. To measure the construct relationships, Structural Equation Model (SEM) approach was used. The results show that management system (b = 0.210; p < 0.05) exerts the highest positive impact on service quality. It followed by psychology and culture (b = 0.188; p < 0.05), empowerment (b = 0.179; p < 0.05) and tangible compensation (b = 0.175; p < 0.05). However, the empirical results suggest that speed of recovery (b = -0.009; p > 0.05) do not influence service quality. The second part of this study uses confirmatory factor analysis (CFA) to analyze and confirm the conceptual model proposed in this research. The result shows that all the values obtained in this study fits the data reasonably well.

A CCD imaging search for wide metal-poor binaries  

NASA Astrophysics Data System (ADS)

We explored the regions within a radius of 25 arcsec around 473 nearby, low-metallicity G- to M-type stars using (VR)I optical filters and small-aperture telescopes. About 10% of the sample was searched up to angular separations of 90 arcsec. We applied photometric and astrometric techniques to detect true physical companions to the targets. The great majority of the sample stars was drawn from the Carney-Latham surveys; their metallicities range from roughly solar to [Fe/H] = -3.5 dex. Our I-band photometric survey detected objects that are between 0 and 5 mag fainter (completeness) than the target stars; the maximum dynamical range of our exploration is 9 mag. We also investigated the literature, and inspected images from the Digitized Sky Surveys to complete our search. By combining photometric and proper motion measurements, we retrieved 29 previously known companions, and identified 13 new proper motion companions. Near-infrared 2MASS photometry is provided for the great majority of them. Low-resolution optical spectroscopy (386-1000 nm) was obtained for eight of the new companion stars. These spectroscopic data confirm them as cool, late-type, metal-depleted dwarfs, with spectral classes from esdK7 to sdM3. After comparison with low-metallicity evolutionary models, we estimate the masses of the proper motion companion stars to be in the range 0.5-0.1 M?. They are moving around their primary stars at projected separations between ˜32 and ˜57 000 AU. These orbital sizes are very similar to those of solar-metallicity stars of the same spectral types. Our results indicate that about 15% of the metal-poor stars have stellar companions in wide orbits, which is in agreement with the binary fraction observed among main sequence G- to M-type stars and T Tauri stars. Based on observations made with the IAC80 telescope operated on the island of Tenerife by the Instituto de Astrofísica de Canarias in the Spanish Observatorio del Teide; also based on observations made with the 2.2 m telescope of the German-Spanish Calar Alto Observatory (Almería, Spain), the William Herschel Telescope (WHT) operated on the island of La Palma by the Isaac Newton Group in the Spanish Observatorio del Roque de los Muchachos (ORM) of the Instituto de Astrofísica de Canarias; and the Telescopio Nazionale Galileo (TNG) at the ORM.

Image search engine with selective filtering and feature-element-based classification  

NASA Astrophysics Data System (ADS)

With the growth of Internet and storage capability in recent years, image has become a widespread information format in World Wide Web. However, it has become increasingly harder to search for images of interest, and effective image search engine for the WWW needs to be developed. We propose in this paper a selective filtering process and a novel approach for image classification based on feature element in the image search engine we developed for the WWW. First a selective filtering process is embedded in a general web crawler to filter out the meaningless images with GIF format. Two parameters that can be obtained easily are used in the filtering process. Our classification approach first extract feature elements from images instead of feature vectors. Compared with feature vectors, feature elements can better capture visual meanings of the image according to subjective perception of human beings. Different from traditional image classification method, our classification approach based on feature element doesn't calculate the distance between two vectors in the feature space, while trying to find associations between feature element and class attribute of the image. Experiments are presented to show the efficiency of the proposed approach.

Analyzing web log files of the health on the net HONmedia search engine to define typical image search tasks for image retrieval evaluation.  

PubMed

Medical institutions produce ever-increasing amount of diverse information. The digital form makes these data available for the use on more than a single patient. Images are no exception to this. However, less is known about how medical professionals search for visual medical information and how they want to use it outside of the context of a single patient. This article analyzes ten months of usage log files of the Health on the Net (HON) medical media search engine. Key words were extracted from all queries and the most frequent terms and subjects were identified. The dataset required much pre-treatment. Problems included national character sets, spelling errors and the use of terms in several languages. The results show that media search, particularly for images, was frequently used. The most common queries were for general concepts (e.g., heart, lung). To define realistic information needs for the ImageCLEFmed challenge evaluation (Cross Language Evaluation Forum medical image retrieval), we used frequent queries that were still specific enough to at least cover two of the three axes on modality, anatomic region, and pathology. Several research groups evaluated their image retrieval algorithms based on these defined topics. PMID:17911928

The CFA BATSE IMAGE SEARCH (CBIS) as used for a Galactic plane survey  

SciTech Connect

The CFA BATSE IMAGE SEARCH (CBIS) system allows automated analysis of large sets of BATSE images. CBIS is being used to conduct a deep survey of the Galactic plane to search for faint transients ({approx}100 mCrab) in the archival data [2]. Furthermore, together with the earth occultation technique [3], CBIS is now applied to a real time imaging survey of the plane to discover new transients and monitor known sources. The CBIS processing is made of two sequential steps: First, the images are scanned to search for excesses. Second, the positions of all these excesses are cross-correlated to produce a list of candidate sources. In this paper, we will detail the algorithms of the scanner and the cross-correlator.

A Fieldable-Prototype Large-Area Gamma-ray Imager for Orphan Source Search  

SciTech Connect

We have constructed a unique instrument for use in the search for orphan sources. The system uses gamma-ray imaging to "see through" the natural background variations that effectively limit the search range of normal devices to ~10 m. The imager is mounted in a 4.9- m-long trailer and can be towed by a large personal vehicle. Source locations are determined both in range and along the direction of travel as the vehicle moves. A fully inertial platform coupled to a Global Positioning System receiver is used to map the gamma-ray images onto overhead geospatial imagery. The resulting images provide precise source locations, allowing rapid follow-up work. The instrument simultaneously searches both sides of the street to a distance of 50 m (100-m swath) for milliCurieclass sources with near-perfect performance.

Global image dissimilarity in macaque inferotemporal cortex predicts human visual search efficiency.  

PubMed

Finding a target in a visual scene can be easy or difficult depending on the nature of the distractors. Research in humans has suggested that search is more difficult the more similar the target and distractors are to each other. However, it has not yielded an objective definition of similarity. We hypothesized that visual search performance depends on similarity as determined by the degree to which two images elicit overlapping patterns of neuronal activity in visual cortex. To test this idea, we recorded from neurons in monkey inferotemporal cortex (IT) and assessed visual search performance in humans using pairs of images formed from the same local features in different global arrangements. The ability of IT neurons to discriminate between two images was strongly predictive of the ability of humans to discriminate between them during visual search, accounting overall for 90% of the variance in human performance. A simple physical measure of global similarity--the degree of overlap between the coarse footprints of a pair of images--largely explains both the neuronal and the behavioral results. To explain the relation between population activity and search behavior, we propose a model in which the efficiency of global oddball search depends on contrast-enhancing lateral interactions in high-order visual cortex.

A neotropical Miocene pollen database employing image-based search and semantic modeling1  

PubMed Central

• Premise of the study: Digital microscopic pollen images are being generated with increasing speed and volume, producing opportunities to develop new computational methods that increase the consistency and efficiency of pollen analysis and provide the palynological community a computational framework for information sharing and knowledge transfer. • Methods: Mathematical methods were used to assign trait semantics (abstract morphological representations) of the images of neotropical Miocene pollen and spores. Advanced database-indexing structures were built to compare and retrieve similar images based on their visual content. A Web-based system was developed to provide novel tools for automatic trait semantic annotation and image retrieval by trait semantics and visual content. • Results: Mathematical models that map visual features to trait semantics can be used to annotate images with morphology semantics and to search image databases with improved reliability and productivity. Images can also be searched by visual content, providing users with customized emphases on traits such as color, shape, and texture. • Discussion: Content- and semantic-based image searches provide a powerful computational platform for pollen and spore identification. The infrastructure outlined provides a framework for building a community-wide palynological resource, streamlining the process of manual identification, analysis, and species discovery.

Building an intranet digital mammography case library  

NASA Astrophysics Data System (ADS)

To practice mammography diagnosis effectively, radiologists expect convenient access to well-organized and authoritative mammography related information, especially when there is case in question. The purpose of this study is to build infrastructural diagnosis support by incorporating various clinical information into a digital mammography case library, and allow user to search the library based on mammographic findings. The digital mammography case library has a three- tier architecture: (1) Back-end mammography databases integrate multimedia clinical information from various operational systems, including RIS and PACS. Cases are stored in a finding index database powered by an object-relational database with finding-coded reports, which are modeled around the ACR BI-RADS (American College of Radiology, Breast Imaging Report and Data System) standard. (2) The middle-end application controllers process application logic, such as user authorization, HTTP request handling, database connection and dynamic HTML page generation. (3) Web-based user interface is developed for authorized Intranet personnel to formulate query based on radiological finding (such as mass, calcification and architectural distortion), shape and assessment, using ACR BI-RADS specified lexicon. The case library so far has 103 cases selected from over 800 digital mammography studies carried out at the Mt. Zion hospital, UCSF, during an on-going digital telemammography project. We believe that an Intranet based digital mammography case library with mammographic finding search capability facilitates continuous medical education and online decision support, by providing exemplary study to compare with case in question.

Hybrid Imaging-Periodicity Search for Radio Pulsars: A Pilot VLA Survey  

NASA Astrophysics Data System (ADS)

Almost all of the ~2300 known pulsars have been discovered using the standard period-dispersion measure (P-DM) search. In a P-DM search, time series intensity data are collected, de-dispersed for a set of trial DMs, and searched for periodic signals usually with frequency-domain algorithms but with fast-folding algorithms for long-period objects. Here we describe a hybrid imaging-periodicity search, an alternate method that uses an imaging survey to select radio point sources as pulsar candidates, followed by a deep P-DM search of these candidates using new or archival data. Since the hybrid search is largely conducted in the imaging domain of time-averaged intensities, it does not suffer reduced sensitivity (as the P-DM method does) when a pulsar signal is heavily modulated by orbital motion, pulse-broadened by scattering, or intermittently emitting (due to large-scale magnetospheric changes, eclipses, etc). As such, the hybrid method is sensitive to systems that are highly selected against in P-DM searches such as compact neutron star binaries, highly scattered millisecond pulsars, and pulsars with spin periods less than a millisecond (should they exist). Interferometric imaging also requires a lower significance threshold for detection than a periodicity search and is more robust against radio-frequency interference. We present preliminary results of a wide-field high dynamic range imaging survey conducted with the Jansky VLA at 1-2 GHz in a pilot program to test the efficacy of a hybrid imaging-periodicity search for radio pulsars in the Galactic plane. The survey region covers four square degrees (Galactic longitudes 32.5-36.5 degrees) using 38 pointings and overlaps with the Arecibo PALFA pulsar survey, which will be used as the periodicity component of our hybrid search. We analyze the observed properties of the 23 known radio pulsars in the survey region and discuss the implications for the selection process needed to narrow the thousands of detected compact sources down to high probability pulsar candidates for a full hybrid survey.

Leveraging Open Standards and Technologies to Search and Display Planetary Image Data  

NASA Astrophysics Data System (ADS)

Mars and the Moon have both been visited by multiple NASA spacecraft. A large number of images and other data have been gathered by the spacecraft and are publicly available in NASA's Planetary Data System. Through a collaboration with Google, Inc., the User Centered Technologies group at NASA Ames Resarch Center has developed at tool for searching and browsing among images from multiple Mars and Moon missions. Development of this tool was facilitated by the use of several open technologies and standards. First, an open-source full-text search engine is used to search both place names on the target and to find images matching a geographic region. Second, the published API of the Google Earth browser plugin is used to geolocate the images on a virtual globe and allow the user to navigate on the globe to see related images. The structure of the application also employs standard protocols and services. The back-end is exposed as RESTful APIs, which could be reused by other client systems in the future. Further, the communication between the front- and back-end portions of the system utilizes open data standards including XML and KML (Keyhole Markup Language) for representation of textual and geographic data. The creation of the search index was facilitated by reuse of existing, publicly available metadata, including the Gazetteer of Planetary Nomenclature from the USGS, available in KML format. And the image metadata was reused from standards-compliant archives in the Planetary Data System. The system also supports collaboration with other tools by allowing export of search results in KML, and the ability to display those results in the Google Earth desktop application. We will demonstrate the search and visualization capabilities of the system, with emphasis on how the system facilitates reuse of data and services through the adoption of open standards.

Library resources are prevalent on the Internet. Library catalogs, electronic books, electronic periodicals, periodical indexes, reference sources, and U.S. Government documents are available by telnet, Gopher, World Wide Web, and FTP. Comparatively few copyrighted library resources are available freely on the Internet. Internet implementations of library resources can add useful features, such as full-text searching. There are discussion lists, Gophers, and World Wide Web pages to help users keep up with new resources and changes to existing ones. The future will bring more library resources, more types of library resources, and more integrated implementations of such resources to the Internet.

An iterative framework for EEG-based image search: robust retrieval with weak classifiers.  

PubMed

We revisit the framework for brain-coupled image search, where the Electroencephalography (EEG) channel under rapid serial visual presentation protocol is used to detect user preferences. Extending previous works on the synergy between content-based image labeling and EEG-based brain-computer interface (BCI), we propose a different perspective on iterative coupling. Previously, the iterations were used to improve the set of EEG-based image labels before propagating them to the unseen images for the final retrieval. In our approach we accumulate the evidence of the true labels for each image in the database through iterations. This is done by propagating the EEG-based labels of the presented images at each iteration to the rest of images in the database. Our results demonstrate a continuous improvement of the labeling performance across iterations despite the moderate EEG-based labeling (AUC <75%). The overall analysis is done in terms of the single-trial EEG decoding performance and the image database reorganization quality. Furthermore, we discuss the EEG-based labeling performance with respect to a search task given the same image database. PMID:23977196

Cuckoo search algorithm based satellite image contrast and brightness enhancement using DWT-SVD.  

PubMed

This paper presents a new contrast enhancement approach which is based on Cuckoo Search (CS) algorithm and DWT-SVD for quality improvement of the low contrast satellite images. The input image is decomposed into the four frequency subbands through Discrete Wavelet Transform (DWT), and CS algorithm used to optimize each subband of DWT and then obtains the singular value matrix of the low-low thresholded subband image and finally, it reconstructs the enhanced image by applying IDWT. The singular value matrix employed intensity information of the particular image, and any modification in the singular values changes the intensity of the given image. The experimental results show superiority of the proposed method performance in terms of PSNR, MSE, Mean and Standard Deviation over conventional and state-of-the-art techniques. PMID:24893835

Methane Imaging Search for Planetary Mass Objects in Rho Ophiuchi  

NASA Astrophysics Data System (ADS)

T dwarfs are the coolest and least massive compact astrophysical objects that we can directly observe outside our Solar System. They share many properties with the expanding population of known exoplanets (almost all of which are inaccessible to direct observation themselves). An understanding of T dwarf atmospheres, therefore, is critical to our developing understanding of exoplanets. Moreover, T dwarf surveys in young star clusters can provide important answers to questions such as ``Is there a minimum mass for star formation?'' and ``How important is dynamical evolution for cluster mass functions?'' In recent years, methane imaging has emerged as a powerful tool for identifying T dwarf candidates in very young clusters, where T dwarfs are at their brightest and have not yet been subject to possible dynamical ejection from their clusters. We have recently conducted a methane imaging survey of the Rho Ophiuchi cluster for T dwarfs using the IRIS2 near-infrared imaging spectrograph on the Anglo-Australian Telescope. The Rho Ophiuchi cluster is the closest (d ˜ 120 parsecs) star-forming region to Earth that has a compact core harboring several hundred young (˜ 1 Myr) stellar objects. In this talk, we present the results of our imaging survey.

iMap: A stable layout for navigating the Astronomy Picture of the Day image collection with embedded search  

NASA Astrophysics Data System (ADS)

Effective techniques for organizing and visualizing large image collections are in growing demand as visual search becomes increasingly popular. Targeting an online astronomy archive -- the Astronomy Picture of the Day (APOD) archive with thousands of images -- we present a practical organizational approach for image search and clustering based on a measure of image similarity that leverages both visual and textual information. To lay out images, we introduce iMap, a treemap-based representation for visualizing and navigating image search and clustering results. We show the effectiveness of our approach by demonstrating experimental results from a comparative user study. The results indicate that iMap makes relevant images in APOD easier to find, in particular for educators seeking astronomy images to augment topical or educational classroom presentations.

An efficient technique for revealing visual search strategies with classification images.  

PubMed

We propose a novel variant of the classification image paradigm that allows us to rapidly reveal strategies used by observers in visual search tasks. We make use of eye tracking, 1/f noise, and a grid-like stimulus ensemble and also introduce a new classification taxonomy that distinguishes between foveal and peripheral processes. We tested our method for 3 human observers and two simple shapes used as search targets. The classification images obtained show the efficacy of the proposed method by revealing the features used by the observers in as few as 200 trials. Using two control experiments, we evaluated the use of naturalistic 1/f noise with classification images, in comparison with the more commonly used white noise, and compared the performance of our technique with that of an earlier approach without a stimulus grid.

Searching for T dwarfs in IC 2391 using methane imaging  

NASA Astrophysics Data System (ADS)

We have performed a 970 arcmin2 (1.75 pc2) survey of the young cluster IC 2391 using the High Acuity Wide field K-band Imager on the Very Large Telescope. Observations were made in both the CH4 and H filters, targeting the methane absorption found in T dwarfs. From our survey of the cluster, five candidate T dwarfs were found. This is substantially smaller than the number that would be found by an equivalent near-infrared broad-band imaging survey, and allowed rapid spectroscopy of all five candidates. Follow-up spectroscopy was carried out using the Folded-port Infrared Echellette on Magellan. These spectra confirm that none of these objects are T dwarfs. This negative result emphasizes the critical importance of follow-up spectroscopy for any photometrically selected candidates, even those from methane imaging. Simulations of the photometric data set, combined with data for known IC 2391 members, imply that the power-law mass function in IC 2391 between 0.003 and 0.13 M? has a slope of ? < 1.7.

Orbital Imaging Radar and the Search for Water on Mars  

NASA Technical Reports Server (NTRS)

The surface of Mars has been modified by a range of geologic processes, and many regions are mantled by varying depths of wind-blown dust, volcanic ash, and fluvially deposited or other water-lain sediments. We are proposing an orbital mission carrying a synthetic aperture radar (SAR) that can penetrate a significant depth of overlying material to reveal the detailed geomorphology as it relates to the changing fluvial, eolian, volcanic, and cratering history of Mars. Moreover, the data to be returned are of direct relevance to the search for past and present occurrences of liquid water, life, changing martian climate, and geologic history (e.g., origin of the northern plains, mechanisms for past and possible present valley formation, and genesis of widespread mantling deposits), the validation of potential landing sites for rover safety, and evaluation of sub-surface accessibility for drilling.

Virtual Screening of Combinatorial Libraries across a Gene Family: in Search of Inhibitors of Giardia lamblia Guanine Phosphoribosyltransferase  

PubMed Central

Parasitic protozoa lack the ability to synthesize purine nucleotides de novo, relying instead on purine salvage enzymes for their survival. Guanine phosphoribosyltransferase (GPRT) from the protozoan parasite Giardia lamblia is a potential target for rational antiparasitic drug design, based on the experimental evidence, which indicates the lack of interconversion between adenine and guanine nucleotide pools. The present study is a continuation of our efforts to use three-dimensional structures of parasitic phosphoribosyltransferases (PRTs) to design novel antiparasitic agents. Two micromolar phthalimide-based GPRT inhibitors were identified by screening the in-house phthalimide library. A combination of structure-based scaffold selection using virtual library screening across the PRT gene family and solid phase library synthesis led to identification of smaller (molecular weight, <300) ligands with moderate to low specificity for GPRT; the best inhibitors, GP3 and GP5, had Ki values in the 23 to 25 ?M range. These results represent significant progress toward the goal of designing potent inhibitors of purine salvage in Giardia parasites. As a second step in this process, altering the phthalimide moiety to optimize interactions in the guanine-binding pocket of GPRT is expected to lead to compounds with promising activity against G. lamblia PRT.

Searching for Cellular Partners of Hantaviral Nonstructural Protein NSs: Y2H Screening of Mouse cDNA Library and Analysis of Cellular Interactome  

PubMed Central

Hantaviruses (Bunyaviridae) are negative-strand RNA viruses with a tripartite genome. The small (S) segment encodes the nucleocapsid protein and, in some hantaviruses, also the nonstructural protein (NSs). The aim of this study was to find potential cellular partners for the hantaviral NSs protein. Toward this aim, yeast two-hybrid (Y2H) screening of mouse cDNA library was performed followed by a search for potential NSs protein counterparts via analyzing a cellular interactome. The resulting interaction network was shown to form logical, clustered structures. Furthermore, several potential binding partners for the NSs protein, for instance ACBD3, were identified and, to prove the principle, interaction between NSs and ACBD3 proteins was demonstrated biochemically.

Our goal is to boost text-based image search results via image reranking. There are diverse modalities (features) of images that we can leverage for reranking, however, the effects of different modalities are query-dependent. The primary challenge we face is how to fuse multiple modalities adaptively for different queries, which has often been overlooked in previous reranking research. Moreover, multimodality fusion without an understanding of the query is risky, and may lead to incorrect judgment in reranking. Therefore, to obtain the best fusion weights for the query, in this paper, we leverage click-through data, which can be viewed as an "implicit" user feedback and an effective means of understanding the query. A novel reranking algorithm, called click-based relevance feedback, is proposed. This algorithm emphasizes the successful use of click-through data for identifying user search intention, while leveraging multiple kernel learning algorithm to adaptively learn the query-dependent fusion weights for multiple modalities. We conduct experiments on a real-world data set collected from a commercial search engine with click-through data. Encouraging experimental results demonstrate that our proposed reranking approach can significantly improve the NDCG@10 of the initial search results by 11.62%, and can outperform several existing approaches for most kinds of queries, such as tail, middle, and top queries.

BSIFT: Toward Data-Independent Codebook for Large Scale Image Search.  

PubMed

Bag-of-Words (BoWs) model based on Scale Invariant Feature Transform (SIFT) has been widely used in large-scale image retrieval applications. Feature quantization by vector quantization plays a crucial role in BoW model, which generates visual words from the high- dimensional SIFT features, so as to adapt to the inverted file structure for the scalable retrieval. Traditional feature quantization approaches suffer several issues, such as necessity of visual codebook training, limited reliability, and update inefficiency. To avoid the above problems, in this paper, a novel feature quantization scheme is proposed to efficiently quantize each SIFT descriptor to a descriptive and discriminative bit-vector, which is called binary SIFT (BSIFT). Our quantizer is independent of image collections. In addition, by taking the first 32 bits out from BSIFT as code word, the generated BSIFT naturally lends itself to adapt to the classic inverted file structure for image indexing. Moreover, the quantization error is reduced by feature filtering, code word expansion, and query sensitive mask shielding. Without any explicit codebook for quantization, our approach can be readily applied in image search in some resource-limited scenarios. We evaluate the proposed algorithm for large scale image search on two public image data sets. Experimental results demonstrate the index efficiency and retrieval accuracy of our approach.

Cathodoluminescence : an imaging technique for the search of extraterrestrial life  

NASA Astrophysics Data System (ADS)

Solids irradiated by a 10-20 keV electron beam emit ligth in the UV-visible range, which is called cathodoluminescence (CL). CL imagery is a powerful tool for visualizing minerals and their internal structures (lattice defects, zoning). For example, terrestrial calcite, either of sedimentary or biogenic origin, often display a bright orange CL, as a result of the incorporation of trace Mn2+ in its lattice. Aragonite can also be discriminated from calcite by its green CL. Carbonates are a major target for the search of life on Mars, and CL imagery could contribute to reveal carbonates in situ. Thomas et al. [1] have validated the concept of an electron lamp to make CL imagery of a rock surface placed in a martian CO2 atmosphere. We present 2 examples of terrestrial bacterial microstructures that are revealed by CL. (1) In Sinemurian sediments from the Montmiral borehole (Valence Basin, France), banded wavy calcite in contact with pyrite represents fossilized biofilms of sulfato-reducing bacteria, as confirmed by the sulfur isotopic composition of pyrite ~+36 %0 PDB. (2) At l'Ile Crémieux, north of the Valence basin, a dense filamentous microbial/fungal community with a bright orange CL signature is embedded in vuggy calcite from a tectonic vein. The mat is anchored 1-2 mm deep in the oolitic veinwall and emerges at right angle in the 'open' fracture space. Finally, carbonate vesicles and exhalite crusts from the Svalbard basalt in Groendland, with orange CL, are shown as analogues to carbonates from the martian ALH84001 igneous meteorite.

Large Spectral Library Problem  

SciTech Connect

Hyperspectral imaging produces a spectrum or vector at each image pixel. These spectra can be used to identify materials present in the image. In some cases, spectral libraries representing atmospheric chemicals or ground materials are available. The challenge is to determine if any of the library chemicals or materials exist in the hyperspectral image. The number of spectra in these libraries can be very large, far exceeding the number of spectral channels collected in the ¯eld. Suppose an image pixel contains a mixture of p spectra from the library. Is it possible to uniquely identify these p spectra? We address this question in this paper and refer to it as the Large Spectral Library (LSL) problem. We show how to determine if unique identi¯cation is possible for any given library. We also show that if p is small compared to the number of spectral channels, it is very likely that unique identi¯cation is possible. We show that unique identi¯cation becomes less likely as p increases.

Search for satellites near (21) Lutetia using OSIRIS/Rosetta images  

NASA Astrophysics Data System (ADS)

On 2010 July 10 the ESA Rosetta mission flew by the large asteroid (21) Lutetia. One of the scientific goals of the onboard OSIRIS instrument was the search for satellites of the asteroid, with more than 20 images specifically dedicated to this topic. An observational campaign was devised with a selection of filters and exposure times tailored to maximize the possibility of detecting small companions and determining their bound orbits. Data were analyzed with suitable methods to remove cosmic ray hits and known background objects, in order to search for persistent detections of potential interesting flux sources. We found no unambiguous detections of a satellite larger than ˜160m inside the entire sphere of gravitational influence. Our search confirmed the absence of bound companions larger than ˜30m inside 20 primary radii. These limits are a factor of ˜30 smaller than the values reported so far from large ground-based telescopes using adaptive optics and from the Hubble Space Telescope.

"Do Users Do What They Think They Do?"- A Comparative Study of User Perceived and Actual Information Searching Behaviour in the National Electronic Library of Infection  

NASA Astrophysics Data System (ADS)

In the last decade, the Internet has profoundly changed the delivery of healthcare. Medical websites for professionals and patients are playing an increasingly important role in providing the latest evidence-based knowledge for professionals, facilitating virtual patient support groups, and providing an invaluable information source for patients. Information seeking is the key user activity on the Internet. However, the discrepancy between what information is available and what the user is able to find has a profound effect on user satisfaction. The UK National electronic Library of Infection (NeLI, www.neli.org.uk) and its subsidiary projects provide a single-access portal for quality-appraised evidence in infectious diseases. We use this national portal, as test-bed for investigating our research questions. In this paper, we investigate actual and perceived user navigation behaviour that reveals important information about user perceptions and actions, in searching for information. Our results show: (i) all users were able to access information they were seeking; (ii) broadly, there is an agreement between "reported" behaviour (from questionnaires) and "observed" behaviour (from web logs), although some important differences were identified; (iii) both browsing and searching were equally used to answer specific questions and (iv) the preferred route for browsing for data on the NeLI website was to enter via the "Top Ten Topics" menu option. These findings provide important insights into how to improve user experience and satisfaction with health information websites.

Halftone-image security improving using overall minimal-error searching.  

PubMed

For image-based data hiding, it is difficult to achieve good image quality when high embedding capacity and 100% data extraction are also demanded. In this study, the proposed method, namely, overall minimal-error searching (OMES) is developed to meet the aforementioned requirements. Moreover, the concept of secret sharing is also adopted to distribute watermarks into multiple halftone images, and the embedded information can only be extracted when all of the marked images are gathered. The OMES modifies the halftone values at the same position of all host images with the trained substitution table (S-Table). The S-Table makes the original combination of these halftone values as another meaningful combination for embedding watermark, which is the key part in determining the image quality. Thus, an optimization procedure is proposed to achieve the optimized S-Table. Two different encoders, called error-diffused-based and least-mean-square-based approaches are also developed to cooperate with the proposed OMES to cope with high processing speed and high image quality applications, respectively. Finally, for resisting the issues caused by the print-and-scan attack, such as zooming, rotation, and dot gain effect, a compensation correction procedure is also proposed. As demonstrated in the experimental results, the proposed approach provides good image quality, and is able to guard against some frequent happened attacks in printing applications. PMID:21435977

Keynote Talk: Mining the Web 2.0 for Improved Image Search  

NASA Astrophysics Data System (ADS)

There are several semantic sources that can be found in the Web that are either explicit, e.g. Wikipedia, or implicit, e.g. derived from Web usage data. Most of them are related to user generated content (UGC) or what is called today the Web 2.0. In this talk we show how to use these sources of evidence in Flickr, such as tags, visual annotations or clicks, which represent the the wisdom of crowds behind UGC, to improve image search. These results are the work of the multimedia retrieval team at Yahoo! Research Barcelona and they are already being used in Yahoo! image search. This work is part of a larger effort to produce a virtuous data feedback circuit based on the right combination many different technologies to leverage the Web itself.

Efficient Feature Detection and Effective Post-Verification for Large Scale Near-Duplicate Image Search  

Microsoft Academic Search

State-of-the-art near-duplicate image search systems mostly build on the bag-of-local features (BOF) representation. While favorable for simplicity and scalability, these systems have three shortcomings: 1) high time complexity of the local feature detection; 2) discriminability reduction of local descriptors due to BOF quantization; and 3) neglect of the geometric relationships among local features after BOF representation. To overcome these shortcomings,

Image copy-move forgery detection based on polar cosine transform and approximate nearest neighbor searching.  

PubMed

Copy-move is one of the most commonly used image tampering operation, where a part of image content is copied and then pasted to another part of the same image. In order to make the forgery visually convincing and conceal its trace, the copied part may subject to post-processing operations such as rotation and blur. In this paper, we propose a polar cosine transform and approximate nearest neighbor searching based copy-move forgery detection algorithm. The algorithm starts by dividing the image into overlapping patches. Robust and compact features are extracted from patches by taking advantage of the rotationally-invariant and orthogonal properties of the polar cosine transform. Potential copy-move pairs are then detected by identifying the patches with similar features, which is formulated as approximate nearest neighbor searching and accomplished by means of locality-sensitive hashing (LSH). Finally, post-verifications are performed on potential pairs to filter out false matches and improve the accuracy of forgery detection. To sum up, the LSH based similar patch identification and the post-verification methods are two major novelties of the proposed work. Experimental results reveal that the proposed work can produce accurate detection results, and it exhibits high robustness to various post-processing operations. In addition, the LSH based similar patch detection scheme is much more effective than the widely used lexicographical sorting. PMID:23149318

An adaptive knowledge-driven medical image search engine for interactive diffuse parenchymal lung disease quantification  

NASA Astrophysics Data System (ADS)

Characterization and quantification of the severity of diffuse parenchymal lung diseases (DPLDs) using Computed Tomography (CT) is an important issue in clinical research. Recently, several classification-based computer-aided diagnosis (CAD) systems [1-3] for DPLD have been proposed. For some of those systems, a degradation of performance [2] was reported on unseen data because of considerable inter-patient variances of parenchymal tissue patterns. We believe that a CAD system of real clinical value should be robust to inter-patient variances and be able to classify unseen cases online more effectively. In this work, we have developed a novel adaptive knowledge-driven CT image search engine that combines offline learning aspects of classification-based CAD systems with online learning aspects of content-based image retrieval (CBIR) systems. Our system can seamlessly and adaptively fuse offline accumulated knowledge with online feedback, leading to an improved online performance in detecting DPLD in both accuracy and speed aspects. Our contribution lies in: (1) newly developed 3D texture-based and morphology-based features; (2) a multi-class offline feature selection method; and, (3) a novel image search engine framework for detecting DPLD. Very promising results have been obtained on a small test set.

Visual search in noise: revealing the influence of structural cues by gaze-contingent classification image analysis.  

PubMed

Visual search experiments have usually involved the detection of a salient target in the presence of distracters against a blank background. In such high signal-to-noise scenarios, observers have been shown to use visual cues such as color, size, and shape of the target to program their saccades during visual search. The degree to which these features affect search performance is usually measured using reaction times and detection accuracy. We asked whether human observers are able to use target features to succeed in visual search tasks in stimuli with very low signal-to-noise ratios. Using the classification image analysis technique, we investigated whether observers used structural cues to direct their fixations as they searched for simple geometric targets embedded at very low signal-to-noise ratios in noise stimuli that had the spectral characteristics of natural images. By analyzing properties of the noise stimulus at observers' fixations, we were able to reveal idiosyncratic, target-dependent features used by observers in our visual search task. We demonstrate that even in very noisy displays, observers do not search randomly, but in many cases they deploy their fixations to regions in the stimulus that resemble some aspect of the target in their local image features.

High-Content Image-Based Screening of a Signal Transduction Pathway Inhibitor Small-Molecule Library against Highly Pathogenic RNA Viruses.  

PubMed

High-content image-based screening was developed as an approach to test a small-molecule library of compounds targeting signal transduction pathways for antiviral activity against multiple highly pathogenic RNA viruses. Of the 2843 compounds screened, 120 compounds exhibited ?60% antiviral activity. Four compounds (E225-0969, E528-0039, G118-0778, and G544-0735), which were most active against Rift Valley fever virus (RVFV) and showed broad-spectrum antiviral activity, were selected for further evaluation for their concentration-response profile and cytotoxicity. These compounds did not show any visible cytotoxicity at the highest concentration of compound tested (200 µM). All four of these compounds were more active than ribavirin against several viruses. One compound, E225-0969, had the lowest effective concentration (EC50 = 1.9-8.92 µM) for all the viruses tested. This compound was 13- and 43-fold more inhibitory against RVFV and Chikungunya virus (CHIKV), respectively, than ribavirin. The highest selectivity index (>106.2) was for E225-0969 against CHIKV. Time-of-addition assays suggested that all four lead compounds targeted early steps in the viral life cycle (entry and/or replication) but not virus egress. Overall, this work demonstrates that high-content image analysis can be used to screen chemical libraries for new antivirals against highly pathogenic viruses. PMID:25342145

Effect of verbal instructions and image size on visual search strategies in basketball free throw shooting.  

PubMed

We assessed the effects on basketball free throw performance of two types of verbal directions with an external attentional focus. Novices (n = 16) were pre-tested on free throw performance and assigned to two groups of similar ability (n = 8 in each). Both groups received verbal instructions with an external focus on either movement dynamics (movement form) or movement effects (e.g. ball trajectory relative to basket). The participants also observed a skilled model performing the task on either a small or large screen monitor, to ascertain the effects of visual presentation mode on task performance. After observation of six videotaped trials, all participants were given a post-test. Visual search patterns were monitored during observation and cross-referenced with performance on the pre- and post-test. Group effects were noted for verbal instructions and image size on visual search strategies and free throw performance. The 'movement effects' group saw a significant improvement in outcome scores between the pre-test and post-test. These results supported evidence that this group spent more viewing time on information outside the body than the 'movement dynamics' group. Image size affected both groups equally with more fixations of shorter duration when viewing the small screen. The results support the benefits of instructions when observing a model with an external focus on movement effects, not dynamics. PMID:11999481

Geospatial Selection Using Mapx and JAZ JavaScript Libraries  

NASA Astrophysics Data System (ADS)

Geospatial selection widgets are becoming more prominent in many online data search tools. In order to make these selection widgets function, it is important to be able to project coordinates from the screen to the earth, and vice-versa. The JavaScript Mapx library enables these projection algorithms to be embedded into a web page, allowing the page to make use of on-the-fly projections in a client browser without having to make calls to a server. This, in turn, can greatly speed up projection calculations, and allow for more robust and interactive functionality in client web applications. The JavaScript JAZ library harnesses the power of the Mapx projections by allowing the user to easily embed a selection widget into any tool requiring a visual geospatial selection mechanism. This relatively lightweight tool provides some significant power by allowing geospatial selections to be done on images of a variety of different map projections. These images can be served from a static image library, or a more dynamic Web Map Server (WMS) setup on a host. The flexibility of this widget has made it possible to use in a variety of web search tools.

Electronic biomedical literature search for budding researcher.  

PubMed

Search for specific and well defined literature related to subject of interest is the foremost step in research. When we are familiar with topic or subject then we can frame appropriate research question. Appropriate research question is the basis for study objectives and hypothesis. The Internet provides a quick access to an overabundance of the medical literature, in the form of primary, secondary and tertiary literature. It is accessible through journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualised, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Scirus, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Several web-libraries (National library Medicine, Cochrane, Web of Science, Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature, levels of evidence, and detail about features of search engine as available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine. Literature search is a dynamic and interactive process; there is no one way to conduct a search and there are many variables involved. It is suggested that a systematic search of literature that uses available electronic resource effectively, is more likely to produce quality research. PMID:24179937

A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature, levels of evidence, and detail about features of search engine as available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine. Literature search is a dynamic and interactive process; there is no one way to conduct a search and there are many variables involved. It is suggested that a systematic search of literature that uses available electronic resource effectively, is more likely to produce quality research. PMID:24179937

Search For Satellites Around Asteroids With Coronagraphic High-contrast Imaging On Adaptive Optics  

NASA Astrophysics Data System (ADS)

High-contrast, coronagraphic imaging with adaptive optics (AO) is a powerful technique for directly detecting exoplanets orbiting nearby stars. We explore the capability of an advanced hardware configuration at the Palomar Hale Telescope to search for satellites around solar system asteroids . Seventeen asteroids, including Ceres, Pallas, and Vesta were observed on April 25 and 26, 2010 in the Ks and J-bands. For each target, we use a 0.41" (0.91" for Ceres) diameter occulting disk to block the light from the primary body. We also observed a nearby calibration star to facilitate point-spread-function (PSF) subtraction. Since asteroids are spatially resolved, additional processing is required compared to stars, which are generally point sources. By subtracting a PSF reference convolved with asteroid disk, we were able to reduce the intensity of speckle noise around the primary body by a factor of 7-10 compared to standard coronagraphy, reaching 5-sigma contrast ratios better than 1e-4 at separations greater than 1" from the center of occulting disk for the best cases. Although our preliminary analysis did not reveal any satellite detections around any of the asteroids, we were able to place strong upper-limits on the size of companions to Ceres of 1 km at 3 Ceres radii, assuming a Ceres-like albedo. Pallas and Vesta have similar detection limits. The results demonstrate that high-contrast imaging techniques widely used on point sources for exoplanet imaging can be effectively adapted to search for km to sub-km sized satellites within 10 radii of large main belt asteroids.

Western Waters Digital Library  

NSDL National Science Digital Library

From the earliest European explorers to the time of modern engineers and hydrologists, the vast reserves of water within the Western United States have been the cause of both great excitement and concern. This compelling digital library brings together a wide range of documents (including legal transcripts, water project records, and personal papers) that document the Columbia, Colorado, Platte, and Rio Grande river basins. The project was completed with support from the Institute of Museum and Library Services and twelve university libraries in eight western states. On the homepage, visitors can perform advanced searches, or just elect to browse through the available materials. Browsing is a good option actually, as all of the materials are contained with one of four sections: subject, people, places, and signature collections. The signature collections are a real find, and visitors can look over troves that include "Native American Water Rights in Arizona", "The Platte River Basin in Nebraska", and "Las Vegas: Water in the West".

Enterprise Reference Library  

NASA Technical Reports Server (NTRS)

Introduction: Johnson Space Center (JSC) offers two extensive libraries that contain journals, research literature and electronic resources. Searching capabilities are available to those individuals residing onsite or through a librarian s search. Many individuals have rich collections of references, but no mechanisms to share reference libraries across researchers, projects, or directorates exist. Likewise, information regarding which references are provided to which individuals is not available, resulting in duplicate requests, redundant labor costs and associated copying fees. In addition, this tends to limit collaboration between colleagues and promotes the establishment of individual, unshared silos of information The Integrated Medical Model (IMM) team has utilized a centralized reference management tool during the development, test, and operational phases of this project. The Enterprise Reference Library project expands the capabilities developed for IMM to address the above issues and enhance collaboration across JSC. Method: After significant market analysis for a multi-user reference management tool, no available commercial tool was found to meet this need, so a software program was built around a commercial tool, Reference Manager 12 by The Thomson Corporation. A use case approach guided the requirements development phase. The premise of the design is that individuals use their own reference management software and export to SharePoint when their library is incorporated into the Enterprise Reference Library. This results in a searchable user-specific library application. An accompanying share folder will warehouse the electronic full-text articles, which allows the global user community to access full -text articles. Discussion: An enterprise reference library solution can provide a multidisciplinary collection of full text articles. This approach improves efficiency in obtaining and storing reference material while greatly reducing labor, purchasing and duplication costs. Most importantly, increasing collaboration across research groups provides unprecedented access to information relevant to NASA s mission. Conclusion: This project is an expansion and cost-effective leveraging of the existing JSC centralized library. Adding key word and author search capabilities and an alert function for notifications about new articles, based on users profiles, represent examples of future enhancements.

Local search for optimal global map generation using mid-decadal landsat images  

USGS Publications Warehouse

NASA and the US Geological Survey (USGS) are seeking to generate a map of the entire globe using Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor data from the "mid-decadal" period of 2004 through 2006. The global map is comprised of thousands of scene locations and, for each location, tens of different images of varying quality to chose from. Furthermore, it is desirable for images of adjacent scenes be close together in time of acquisition, to avoid obvious discontinuities due to seasonal changes. These characteristics make it desirable to formulate an automated solution to the problem of generating the complete map. This paper formulates a Global Map Generator problem as a Constraint Optimization Problem (GMG-COP) and describes an approach to solving it using local search. Preliminary results of running the algorithm on image data sets are summarized. The results suggest a significant improvement in map quality using constraint-based solutions.

Petrucci Music Library  

NSDL National Science Digital Library

The Petrucci Music Library is an essential database for musicians, music librarians and teachers, as well as lovers of classical music. The online collection shares public domain music via a searchable interface. On the main page, visitors may search for works by composer (or composer's nationality), genre, time period, or melody. Searching by melody is particularly interesting, as it launches an interactive keyboard on which users may play (or, for those of us less musically inclined, attempt to play) a familiar melody in order to search the database for it. Some searches will yield YouTube clips of the music. The website also provides scans of sheet music from many composers, genres and world locations. [AHT

Searching for Binary Systems in Planetary Nebulae Using the ISIS Image Subtraction Software  

NASA Astrophysics Data System (ADS)

We are exploring the theory that binary central stars of planetary nebulae are a contributing factor in the formation of planetary nebulae. Since periodic variability is indicative of a close binary system, we search for photometric variability in the central stars of planetary nebulae. The variability of our targets is assessed with the image subtraction software, ISIS. We find that the central stars of the planetary nebulae Hen 2-84 and NGC 6326 show variability. A preliminary light curve for Hen 2-84 shows periodic behavior, suggesting a binary system. We do not have sufficient data for NGC 6326 to determine periodicity, but our results are consistent with previous work that does show periodic behavior. Of the remaining targets observed, with sufficient data, seven do not appear to have substantial variability detected through ISIS and two targets have undeterminable variability.

Optimized analysis method for indirect dark matter searches with imaging air Cherenkov telescopes  

SciTech Connect

We propose a dedicated analysis approach for indirect Dark Matter searches with Imaging Air Cherenkov Telescopes. By using the full likelihood analysis, we take complete advantage of the distinct features expected in the gamma ray spectrum of Dark Matter origin, achieving better sensitivity with respect to the standard analysis chains. We describe the method and characterize its general performance. We also compare its sensitivity with that of the current standards for several Dark Matter annihilation models, obtaining gains of up to factors of order of 10. We compute the improved limits that can be reached using this new approach, taking as an example existing estimates for several benchmark models as well as the recent results from VERITAS on observations of the dwarf spheroidal galaxy Segue 1. Furthermore, we estimate the sensitivity of Cherenkov Telescopes for monochromatic line signals. Predictions are made on improvement that can be achieved for MAGIC and CTA. Lastly, we discuss how this method can be applied in a global, sensitivity-optimized indirect Dark Matter search that combines the results of all Cherenkov observatories of the present generation.

Folger Shakespeare Library  

NSDL National Science Digital Library

The Folger Shakespeare Library opened in 1932 as a gift to the United States from Henry Clay Folger and his wife Emily Jordan Folger. Located in Washington, DC, the Library continues to be administered by a board of governors from Amherst College, Mr. Folger's alma mater. As one might imagine, the site has a great deal to offer those looking for materials related to Shakespeare, and the "Discover Shakespeare" area is a good place to start in this regard. In this area, visitors can learn about Shakespeare's life, his works, and even view images from some of his rare folios held by the Library. Scholars and others will find that the "Use the Collection" area is invaluable as well. Here visitors can learn about fellowship programs offered by the Library, and more importantly, they can also browse through their digital collection, which contains over 20,000 images. These images include books, theater memorabilia, manuscripts, and letters. Finally, visitors can also sign up to receive electronic news updates and also learn about their upcoming theatrical productions.

A visual-search model observer for multislice-multiview SPECT images  

PubMed Central

Purpose: Mathematical model observers are intended for efficient assessment of diagnostic image quality, but model-observer studies often are not representative of clinical realities. Model observers based on a visual-search (VS) paradigm may allow for greater clinical relevance. The author has compared the performances of several VS model observers with those of human observers and an existing scanning model observer for a study involving nodule detection and localization in simulated Tc-99m single-photon emission computed tomography (SPECT) lung volumes. Methods: A localization receiver operating characteristic (LROC) study compared two iterative SPECT reconstruction strategies: an all-corrections (AllC) strategy with compensations for attenuation, scatter, and distance-dependent camera resolution and an “RC” strategy with resolution compensation only. Nodules in the simulation phantom were of three different relative contrasts. Observers in the study had access to the coronal, sagittal, and transverse displays of the reconstructed volumes. Three human observers each read 50 training volumes and 100 test volumes per reconstruction strategy. The same images were analyzed by a channelized nonprewhitening (CNPW) scanning observer and two VS observers. The VS observers implemented holistic search processes that identified focal points of Tc-99m uptake for subsequent analysis by the CNPW scanning model. The level of prior knowledge about the background structure in the images was a study variable for the model observers. Performance was scored by area under the LROC curve. Results: The average human-observer performances were respectively 0.67 ± 0.04 and 0.61 ± 0.03 for the RC and AllC strategies. Given approximate knowledge about the background structure, both VS models scored 0.69 ± 0.08 (RC) and 0.66 ± 0.08 (AllC). The scanning observer reversed the strategy ranking in scoring 0.73 ± 0.08 with the AllC strategy and 0.64 ± 0.08 with the RC strategy. The VS observers exhibited less sensitivity to variations in background knowledge compared to the scanning observer. Conclusions: The VS framework has the potential to increase the clinical similitude of model-observer studies and to enhance the ability of existing model observers to quantitatively predict human-observer performance.

Direct imaging search for planets around low-mass stars and spectroscopic characterization of young exoplanets  

NASA Astrophysics Data System (ADS)

Low--mass stars between 0.1--0.6 M? are the most abundant members our galaxy and may be the most common sites of planet formation, but little is known about the outer architecture of their planetary systems. We have carried out a high-contrast adaptive imaging search for gas giant planets between 1--13 MJup around 122 newly identified young M dwarfs in the solar neighborhood ( ? 35 pc). Half of our targets are younger than 145 Myr, and 90% are younger than 580 Myr. After removing 39 resolved stellar binaries, our homogeneous sample of 83 single young M dwarfs makes it the largest imaging search for planets around low--mass stars to date. Our H- and K- band coronagraphic observations with Subaru/HiCIAO and Keck/NIRC2 achieve typical contrasts of 9--13 mag and 12--14 mag at 100, respectively, which corresponds to limiting masses of ˜1--10 M Jup at 10--30 AU for most of our sample. We discovered four brown dwarfs with masses between 25--60 MJup at projected separations of 4--190 AU. Over 100 candidate planets were discovered, nearly all of which were found to be background stars from follow-up second epoch imaging. Our null detection of planets nevertheless provides strong statistical constraints on the occurrence rate of giant planets around M dwarfs. Assuming circular orbits and a logarithmically-flat power law distribution in planet mass and semi--major axis of the form d 2N=(dloga dlogm) infinity m0 a0, we measure an upper limit (at the 95% confidence level) of 8.8% and 12.6% for 1--13 MJup companions between 10--100 AU for hot start and cold start evolutionary models, respectively. For massive gas giant planets in the 5--13 M Jup range like those orbiting HR 8799, GJ 504, and beta Pictoris, we find that fewer than 5.3% (7.8%) of M dwarfs harbor these planets between 10--100 AU for a hot start (cold start) formation scenario. Our best constraints are for brown dwarf companions; the frequency of 13--75 MJup companions between (de--projected) physical separations of 10--100 AU is 2.1+2.1-1.2 %. Altogether, our results show that gas giant planets, especially massive ones, are rare in the outskirts of M dwarf planetary systems. If disk instability is a viable way to form planets, our constraints for the most common type of star imply that overall it is an inefficient mechanism.

Automatic correspondence using the enhanced hexagonal center-based inner search algorithm for point-based dental image registration.  

PubMed

In this paper a modified version of the center-based inner search algorithm, the enhanced hexagonal center-based inner search algorithm, for automatic point correspondence is proposed towards dental registration. The modified algorithm is incorporated within a general registration scheme which is based on extracting a set of candidate points on the reference image, finding their corresponding points in the other image (float image) using the proposed algorithm and applying an affine geometrical transformation towards automatic registration. The performance of the proposed algorithm is evaluated against a well-known method for automatic correspondence, in terms of the registration accuracy. Qualitative and quantitative results on registering 24 dental pairs showed that the proposed algorithm outperforms the other method for automatic correspondence. PMID:17946045

Mapping of low-frequency chimeric yeast artificial chromosome libraries from human chromosomes 16 and 21 by fluorescence in situ hybridization and quantitative image analysis  

SciTech Connect

Yeast artificial chromosome (YAC) clones from low-frequency chimeric libraries of human chromosomes 16 and 21 were mapped onto human diploid fibroblast metaphase chromosomes using fluorescence in situ hybridization (FISH) and digital imaging microscopy. YACs mapped onto chromosome 21 were selected to provide subregional location and ordering of known and unknown markers on the long arm of chromosome 21, particularly in the Down syndrome region (q22). YACs mapped onto chromosome 16 were selected to overlap regions spanning chromosome 16 cosmid maps. YAC clones were indirectly labeled with fluorescein, and the total DNA of the chromosome was counterstained with propidium iodide. A single image containing both the FISH signal and the whole chromosome was acquired for each chromosome of interest containing the fluorescent probe signal in a metaphase spread. From the digitized image, the fluorescence intensity profile through the long axis of the chromosome gave the total chromosome length and the probe position. The map position of the probe was expressed as the fractional length (FL) of the total chromosome relative to the end of the short arm (Flpter). From each clone hybridized, 20-40 chromosome images were analyzed. Thirty-eight YACs were mapped onto chromosome 16, and their FLs were distributed along the short and long arms. On chromosome 21, 47 YACs were mapped, including 12 containing known markers. To confirm the order of a dense population of YACs within the Down syndrome region, a two-color mapping strategy was used in which an anonymous YAC was located relative to one or two known markers on the metaphase chromosome. The chromosome FL maps have a 1- to 2-Mb resolution, and the FL measurement of each probe has a typical standard error of 0.5-1 Mb. 14 refs., 3 figs., 3 tabs.

Comparison of Iranian National Medical Library with digital libraries of selected countries  

PubMed Central

Introduction: The important role of information and communication technologies and their influence on methods of storing, retrieving information in digital libraries, has not only changed the meanings behind classic library activates but has also created great changes in their services. However, it seems that not all digital libraries provide their users with similar services and only some of them are successful in fulfilling their role in digital environment. The Iranian National Medical library is among those that appear to come short compared to other digital libraries around the world. By knowing the different services provided by digital libraries worldwide, one can evaluate the services provided by Iranian National Medical library. The goal of this study is a comparison between Iranian National Medical library and digital libraries of selected countries. Materials and Methods: This is an applied study and uses descriptive – survey method. The statistical population is the digital libraries around the world which were actively providing library services between October and December 2011 and were selected by using the key word “Digital Library” in Google search engine. The data-gathering tool was direct access to the websites of these digital libraries. The statistical study is descriptive and Excel software was used for data analysis and plotting of the charts. Results: The findings showed that among the 33 digital libraries investigated worldwide, most of them provided Browse (87.87%), Search (84.84%), and Electronic information retrieval (57.57%) services. The “Help” in public services (48/48%) and “Interlibrary Loan” in traditional services (27/27%) had the highest frequency. The Iranian National Medical library provides more digital services compared to other libraries but has less classic and public services and has less than half of possible public services. Other than Iranian National Medical library, among the 33 libraries investigated, the leaders in providing different services are Library of University of California in classic services, Count Way Library of Medicine in digital services, and Library of Finland in public services. Results and Discussion: The results of this study show that among the digital libraries investigated, most provided similar public, digital, and classic services and The Iranian National Medical library has been somewhat successful in providing these services compared to other digital libraries. One can also conclude that the difference in services is at least in part due to difference in environments, information needs, and users. Conclusion: Iranian National Medical Library has been somewhat successful in providing library services in digital environment and needs to identify the services which are valuable to its users by identifying the users’ needs and special characteristics of its environment PMID:25540782

High Content Image-Based Screening of a Protease Inhibitor Library Reveals Compounds Broadly Active against Rift Valley Fever Virus and Other Highly Pathogenic RNA Viruses  

PubMed Central

High content image-based screening was developed as an approach to test a protease inhibitor small molecule library for antiviral activity against Rift Valley fever virus (RVFV) and to determine their mechanism of action. RVFV is the causative agent of severe disease of humans and animals throughout Africa and the Arabian Peninsula. Of the 849 compounds screened, 34 compounds exhibited ?50% inhibition against RVFV. All of the hit compounds could be classified into 4 distinct groups based on their unique chemical backbone. Some of the compounds also showed broad antiviral activity against several highly pathogenic RNA viruses including Ebola, Marburg, Venezuela equine encephalitis, and Lassa viruses. Four hit compounds (C795-0925, D011-2120, F694-1532 and G202-0362), which were most active against RVFV and showed broad-spectrum antiviral activity, were selected for further evaluation for their cytotoxicity, dose response profile, and mode of action using classical virological methods and high-content imaging analysis. Time-of-addition assays in RVFV infections suggested that D011-2120 and G202-0362 targeted virus egress, while C795-0925 and F694-1532 inhibited virus replication. We showed that D011-2120 exhibited its antiviral effects by blocking microtubule polymerization, thereby disrupting the Golgi complex and inhibiting viral trafficking to the plasma membrane during virus egress. While G202-0362 also affected virus egress, it appears to do so by a different mechanism, namely by blocking virus budding from the trans Golgi. F694-1532 inhibited viral replication, but also appeared to inhibit overall cellular gene expression. However, G202-0362 and C795-0925 did not alter any of the morphological features that we examined and thus may prove to be good candidates for antiviral drug development. Overall this work demonstrates that high-content image analysis can be used to screen chemical libraries for new antivirals and to determine their mechanism of action and any possible deleterious effects on host cellular biology.

Beach dune systems are important for coastal zone ecosystems as they provide natural sea defences that dissipate wave energy. Geomorphological models of this near-shore topography require site-specific sediment composition, grain size and moisture content as inputs. Hyperspectral, field radiometry and LiDAR remote sensing can be used as tools by providing synoptic maps of these properties. However, multi-remote sensing of near-shore beach images can only be interpreted if there are adequate bio-geophysical or empirical models for information extraction. Our aim was thus to model the effects of varying sediment properties on the reflectance in both field and laboratory conditions within the FHyL (Field Spectral Libraries, Airborne Hyperspectral Images and Topographic LiDAR) procedure, using a multisource dataset (airborne Hyperspectral - MIVIS and topographic LiDAR - Hawk-eye II and field radiometry). The methodology consisted of (i) acquisition of simultaneous multi-source datasets (airborne Hyperspectral - MIVIS and topographic LiDAR - Hawk-eye) (ii) hyperspectral measurements of sediment mixtures with varying physical characteristics (moisture, grain size and minerals) in field and laboratory conditions, (iii) determination and quantification of specific absorption features, and (iv) correlation between the absorption features and physical parameters cited above. Results showed the potential of hyperspectral signals to assess the effect of moisture, grain-size and mineral composition on sediment properties.

Cuneiform Digital Library Initiative  

NSDL National Science Digital Library

The Cuneiform Digital Library Initiative (CDLI) is an international group of Assyriologists, museum curators and historians making available cuneiform tablets dating from the beginning of writing, ca. 3200 B.C., until the end of the third millennium. Led by a team at the University of California at Los Angeles, with initial National Science Foundation funding, this ambitious project seeks expose the collections within the US, Germany, Austria, and the Czech Republic, to a broad audience of specialists, scholars and advanced students. The presently limited (but growing) data set consists of text and image (current library entries offer high quality images), combining document transliterations, text glossaries and digitized originals and photo archives of early cuneiform. To promote discussion and scholarship, CDLI established two, English language, electronic journals which are currently accepting submissions, Cuneiform Digital Library Bulletin (for the rapid distribution of short notes) and the Cuneiform Digital Library Journal (more substantive scholarly contributions). The initial contributions will be made available in March 2002. This collection can be somewhat difficult to navigate, but offers a great opportunity to interested scholars and students.

Visual Search of Experts in Medical Image Reading: The Effect of Training, Target Prevalence, and Expert Knowledge  

PubMed Central

The aims of this study are (a) To determine the effect of training on the multiple-target lesion search performance; and (b) To examine the effect of target prevalence on the performance of radiologists and novices. We conducted four sessions of 500 trials in a lesion search on a medical image task in which participants searched for three different target lesions. Participants were 10 radiologists and novices. In each session, the prevalence of the different target lesions varied from low (2%) to high (40%). The sensitivity of novices was higher in the later sessions than in the first session, whereas there were no differences among sessions in radiologists. The improvement on sensitivity of novices was largely due to attenuations of false alarm (FA) errors. In addition, miss rates of the three targets did not differ in data of novices, whereas radiologists produced a higher miss rate for the highest prevalence target lesion (non-serious lesion) than for the other two lesions (serious lesions). The conclusions are (a) The training for the multiple-target lesion search task can be effective to reduce FA errors; and (b) The prevalence effect on lesion search can be attenuated by the multiple-target identification and the knowledge about seriousness of lesions. This suggests that acquired knowledge about normal cases and serious lesions is an important aspect of a radiologists’ skill in searching for medical lesions and their high performance levels.

Shaping the library of the future: Digital library developments at Los Alamos National Laboratory`s Research Library  

SciTech Connect

This paper offers an overview of current efforts at the Research Library, Los Alamos National Laboratory, (LANL), to develop digital library services. Current projects of LANL`s Library without Walls initiative are described. Although the architecture of digital libraries generally is experimental and subject to debate, one principle of LANL`s approach to delivering library information is the use of Mosaic as a client for the Research Library`s resources. Several projects under development have significant ramifications for delivering library services over the Internet. Specific efforts via Mosaic include support for preprint databases, providing access to citation databases, and access to a digital image database of unclassified Los Alamos technical reports.

CPL: Common Pipeline Library  

NASA Astrophysics Data System (ADS)

The Common Pipeline Library (CPL) is a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit to create automated astronomical data reduction pipelines. Though initially developed as a standardized way to build VLT instrument pipelines, the CPL may be more generally applied to any similar application. The code also provides a variety of general purpose image- and signal-processing functions, making it an excellent framework for the creation of more generic data handling packages. The CPL handles low-level data types (images, tables, matrices, strings, property lists, etc.) and medium-level data access methods (a simple data abstraction layer for FITS files). It also provides table organization and manipulation, keyword/value handling and management, and support for dynamic loading of recipe modules (using programs such as EsoRex).

Search and retrieval of medical images for improved diagnosis of neurodegenerative diseases  

NASA Astrophysics Data System (ADS)

In the medical world, the accuracy of diagnosis is mainly affected by either lack of sufficient understanding of some diseases or the inter-, and/or intra-observer variability of the diagnoses. The former requires understanding the progress of diseases at much earlier stages, extraction of important information from ever growing amounts of data, and finally finding correlations with certain features and complications that will illuminate the disease progression. The latter (inter-, and intra- observer variability) is caused by the differences in the experience levels of different medical experts (inter-observer variability) or by mental and physical tiredness of one expert (intra-observer variability). We believe that the use of large databases can help improve the current status of disease understanding and decision making. By comparing large number of patients, some of the otherwise hidden relations can be revealed that results in better understanding, patients with similar complications can be found, the diagnosis and treatment can be compared so that the medical expert can make a better diagnosis. To this effect, this paper introduces a search and retrieval system for brain MR databases and shows that brain iron accumulation shape provides additional information to the shape-insensitive features, such as the total brain iron load, that are commonly used in the clinics. We propose to use Kendall's correlation value to automatically compare various returns to a query. We also describe a fully automated and fast brain MR image analysis system to detect degenerative iron accumulation in brain, as it is the case in Alzheimer's and Parkinson's. The system is composed of several novel image processing algorithms and has been extensively tested in Leiden University Medical Center over so far more than 600 patients.

NSDL National Science Digital Library

This fine Website provides searchable access to a number of voluminous document collections from diverse sources around the world in the fields of history, humanitarian and global development, computer science, music, and literature. These databases are chock full of documents, reports, articles, bibliographies, periodicals, and audio/ video files. The Website's searching and browsing interfaces are provided by Greenstone digital library software and enable easy, effective searching through these substantial collections, which include materials from the UN University, the Food and Agriculture organization, the Humanity Development Library, the World Environment Library, the Bibliotheque pour le Developpement, and more. Also included here are interfaces for the Gutenberg Project (see the November 22, 1996 Scout Report), a women's history collection, a youth oral history covering the lives of New Zealand children in the pre- and post-World War II years, the New Zealand Digital Music Library, and even an extensive music video collection (note: download times for videos can be several minutes). Two of the collections -- on Arabic and Chinese studies -- appear to be still under construction. The great boon of the site, of course, is the fact that rather than simply serving as a gateway, it allows users to immediately access the various materials brought up by the interface. "The New Zealand Digital Library project is a research program at The University of Waikato whose aim is to develop the underlying technology for digital libraries and make it available publicly so that others can use it to create their own collections."

The official Web presence of the military education libraries in the United States and Europe, MERLN links together the holdings and electronic information resources of fourteen libraries, collectively the "largest and most comprehensive collections of military information resources in the world." Users can select a Topic Area (or create a custom topic) or a specific catalog, and then search by title, author, subject heading, or advanced options. The databases are also browseable by author, title, subject, or year. A sample search under title keyword for all libraries for "carpet bombing" produced 74 hits, while "Antietam" produced 266. Hits for each library are listed in a frame on the left-hand side, while basic bibliographic information on each title is listed on the right, with links to more detailed information. Users can repeat previous searches and combine them with other searches using the History option and also save and email selected search returns. Please note that at present the library catalogs for the Marine Corps University Research Center, the Marshall Center, the US Coast Guard Academy, and the US Naval Academy cannot be directly searched from MERLN, but efforts are underway to correct the problem. Users can access the homepages of these libraries, and all of the others linked through MERLN, from the main page.

The 2MASS Wide-Field T Dwarf Search. IV. Hunting Out T Dwarfs with Methane Imaging  

NASA Astrophysics Data System (ADS)

We present first results from a major program of methane filter photometry for low-mass stars and brown dwarfs. The definition of a new methane filter photometric system is described. A recipe is provided for the differential calibration of methane imaging data using existing Two Micron All Sky Survey (2MASS) photometry. We show that these filters are effective in discriminating T dwarfs from other types of stars, and we demonstrate this with Anglo-Australian Telescope observations using the IRIS2 imager. Methane imaging data and proper motions are presented for 10 T dwarfs identified as part of the 2MASS Wide-Field T Dwarf Search, seven of them initially identified as T dwarfs using methane imaging. We also present near-infrared moderate-resolution spectra for five T dwarfs newly discovered by this technique. Spectral types obtained from these spectra are compared to those derived from both our methane filter observations and spectral types derived by other observers. Finally, we suggest a range of future programs to which these filters are clearly well suited: the winnowing of T dwarf and Y dwarf candidate objects coming from the next generation of near-infrared sky surveys, the robust detection of candidate planetary-mass brown dwarfs in clusters, the detection of T dwarf companions to known L and T dwarfs via deep methane imaging, and the search for rotationally modulated time-variable surface features on cool brown dwarfs. Based on observations obtained at the Anglo-Australian Telescope, Siding Spring, Australia.

Collection Metadata Solutions for Digital Library Applications  

NASA Technical Reports Server (NTRS)

Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemas that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadata "registers" the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system.

Victoria and Albert Museum Images  

NSDL National Science Digital Library

The official site of London's V&A, the largest museum of decorative arts in the world, has a image database containing images of over 10,000 objects. While the snazzy interface may be slow to load or difficult to read in some browsers, the image database loads and operates relatively quickly. Users can search the database by keyword or by an advanced search. Results include small thumbnails displayed chronologically (or by country or object type) which link to briefly annotated larger images. The V&A homepage offers information about the museum and its current exhibition on Art Nouveau and links to the National Art Library (located in the V&A) and the 24 Hour Museum Website (reviewed in the August 13, 1999 Scout Report).

Content-based image retrieval for brain MRI: An image-searching engine and population-based analysis to utilize past clinical data for future diagnosis  

PubMed Central

Radiological diagnosis is based on subjective judgment by radiologists. The reasoning behind this process is difficult to document and share, which is a major obstacle in adopting evidence-based medicine in radiology. We report our attempt to use a comprehensive brain parcellation tool to systematically capture image features and use them to record, search, and evaluate anatomical phenotypes. Anatomical images (T1-weighted MRI) were converted to a standardized index by using a high-dimensional image transformation method followed by atlas-based parcellation of the entire brain. We investigated how the indexed anatomical data captured the anatomical features of healthy controls and a population with Primary Progressive Aphasia (PPA). PPA was chosen because patients have apparent atrophy at different degrees and locations, thus the automated quantitative results can be compared with trained clinicians' qualitative evaluations. We explored and tested the power of individual classifications and of performing a search for images with similar anatomical features in a database using partial least squares-discriminant analysis (PLS-DA) and principal component analysis (PCA). The agreement between the automated z-score and the averaged visual scores for atrophy (r = 0.8) was virtually the same as the inter-evaluator agreement. The PCA plot distribution correlated with the anatomical phenotypes and the PLS-DA resulted in a model with an accuracy of 88% for distinguishing PPA variants. The quantitative indices captured the main anatomical features. The indexing of image data has a potential to be an effective, comprehensive, and easily translatable tool for clinical practice, providing new opportunities to mine clinical databases for medical decision support.

Historical Postcards of New York City from the Picture Collection at Mid-Manhattan Library  

NSDL National Science Digital Library

From Van Cortland Park in the Bronx down to the bucolic stylings of Staten Island in the late 19th century, this very fun online exhibition from the New York Public Library will sate the desires of those persons with a penchant for historical postcards. Recently, the Library placed five hundred postcards depicting views of all five boroughs in the late 19th and early 20th century within the much larger NYPL Digital Gallery. This exhibition offers a brief introduction to these depictions of New York's past, and visitors can get a taste of the images by looking through sections that include "A Record of Time", "A Record of Place", and "A Record of the People". Visitors can look at promenades in Central Park, the early days of Riverside Drive, and the Astor Library. After that, they can perform their own postcard searches, and purists will note that the back of every postcard has also been scanned for this project.

Afghanistan Digital Library  

NSDL National Science Digital Library

The goal of the Afghanistan Digital Library at New York University is "to retrieve and restore the first sixty years of Afghanistan's published cultural heritage." This period, from 1871 to 1930, is of great importance as the earliest publications from this time frame are very rare and decades of war have not helped the situation. A team of scholars working at the National Archives in Kabul and NYU has helped to digitize a number of these documents for inclusion in this digital library. The project is sponsored by NYU Libraries, the National Endowment for the Humanities, and The Reed Foundation. Currently, the archive contains over 380 books, and visitors can browse them at their leisure. There is a search feature, but as the transliteration part of the project is still in development, visitors might just want to look around at items they find compelling. The viewer application is quite user-friendly, and visitors can zoom in to examine various details of each work.

Bates College Digital Library  

NSDL National Science Digital Library

Bates College in Lewiston, Maine has created this site to provide access to some of the holdings in the Edmund S. Muskie Archives and Special Collections Library. Appropriately enough, the library holds the papers of Muskie, who served as the governor of Maine from 1955 to 1959, and then as one of the United States senators from the state from 1959 to 1980. One of the collections here consists of more than 400 interviews with individuals who knew, affected, or were affected by Senator Muskie. Visitors to the site can browse each interview, and in many cases, the interviews include an audio recording, a transcript and a summary sheet. Interested parties can search for particular words in each transcript and browse by interviewer, interviewee, and interviewer number. In addition, the site includes access to some of the 10,000 historic photographs of Bates College. This section of the site documents the life of the institution from 1875 to the present day, and users can search for photographs of classroom activities, clubs, dorm life, and theater.

Land Treatment Digital Library  

USGS Publications Warehouse

A dynamic system to enter, store, retrieve, and analyze Federal land-treatment data. More information and access to data available at: http://greatbasin.wr.usgs.gov/ltdl Across the country, public land managers make hundreds of decisions each year that influence landscapes and ecosystems within the lands they manage. Many of these decisions involve vegetation manipulations known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. Data on these land treatments are usually stored at local offices, and gathering information across large spatial areas can be difficult. There is a need to centralize and store treatment data for Federal agencies involved in land treatments because these data are useful to land managers for policy and management and to scientists for developing sampling designs and studies. The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The project was developed and has been refined based on feedback from partner agencies and stakeholders, with opportunity for the library holdings to expand as new information becomes available. The library contains data in text, tabular, spatial, and image formats. Specific examples include project plans and implementation reports, monitoring data, spatial data files from geographic information systems, digitized paper maps, and digital images of land treatments. The data are entered by USGS employees and are accessible through a searchable web site. The LTDL can be used to respond to information requests, conduct analyses and other forms of information syntheses, produce maps, and generate reports for DOI managers and scientists and other authorized users.

Facilitating medical information search using Google Glass connected to a content-based medical image retrieval system.  

PubMed

Wearable computing devices are starting to change the way users interact with computers and the Internet. Among them, Google Glass includes a small screen located in front of the right eye, a camera filming in front of the user and a small computing unit. Google Glass has the advantage to provide online services while allowing the user to perform tasks with his/her hands. These augmented glasses uncover many useful applications, also in the medical domain. For example, Google Glass can easily provide video conference between medical doctors to discuss a live case. Using these glasses can also facilitate medical information search by allowing the access of a large amount of annotated medical cases during a consultation in a non-disruptive fashion for medical staff. In this paper, we developed a Google Glass application able to take a photo and send it to a medical image retrieval system along with keywords in order to retrieve similar cases. As a preliminary assessment of the usability of the application, we tested the application under three conditions (images of the skin; printed CT scans and MRI images; and CT and MRI images acquired directly from an LCD screen) to explore whether using Google Glass affects the accuracy of the results returned by the medical image retrieval system. The preliminary results show that despite minor problems due to the relative stability of the Google Glass, images can be sent to and processed by the medical image retrieval system and similar images are returned to the user, potentially helping in the decision making process.

A NASA contract led to the development of faster and more energy efficient semiconductor materials for digital integrated circuits. Gallium arsenide (GaAs) conducts electrons 4-6 times faster than silicon and uses less power at frequencies above 100-150 megahertz. However, the material is expensive, brittle, fragile and has lacked computer automated engineering tools to solve this problem. Systems & Processes Engineering Corporation (SPEC) developed a series of GaAs cell libraries for cell layout, design rule checking, logic synthesis, placement and routing, simulation and chip assembly. The system is marketed by Compare Design Automation.

A MEMS-based spectral-polarimetric imaging and target tracking architecture for airborne broad-area search  

NASA Astrophysics Data System (ADS)

We describe a compact, multi-sensor design architecture capable of providing both spectral-polarimetric imaging and adaptive matched filter target detection in real-time. The sensor suite supports airborne broad-area search missions using multiple large-format, high speed TDI scanning sensors. The technology approach leverages Micro-Electro-Mechanical System (MEMS) based spectral imaging systems and scanning TDI arrays originally developed for space based remote sensing. The MEMS spectrometer system can dynamically select and switch linear combinations of single or multiple VNIR/SWIR spectral bands with 5nm sampling resolution using a programmable MEMS mirror. The MEMS spectral filter is capable of providing high quality spectral filtering across a large format sensor with > 1MHz optical switching & update speeds. A dual instrument sensor suite architecture called the "PRISM sensor" has been developed which is based on this technology and provides simultaneous spectral-polarimetric imaging and matched filter target tracking with minimal on-board computing requirements. We describe how this technology can simultaneously perform broad-area imaging and target identification in near real-time with a simple threshold operation. Preliminary results are illustrated as additional layer of target-discriminate geospatial information that may be fused with geo-referenced imagery.

Search without Boundaries Using Simple APIs  

USGS Publications Warehouse

The U.S. Geological Survey (USGS) Library, where the author serves as the digital services librarian, is increasingly challenged to make it easier for users to find information from many heterogeneous information sources. Information is scattered throughout different software applications (i.e., library catalog, federated search engine, link resolver, and vendor websites), and each specializes in one thing. How could the library integrate the functionalities of one application with another and provide a single point of entry for users to search across? To improve the user experience, the library launched an effort to integrate the federated search engine into the library's intranet website. The result is a simple search box that leverages the federated search engine's built-in application programming interfaces (APIs). In this article, the author describes how this project demonstrated the power of APIs and their potential to be used by other enterprise search portals inside or outside of the library.

The British Library: Listen to Nature  

NSDL National Science Digital Library

The British Library's new Listen to Nature web site features 400 recordings selected from the more than 150,000 animal sounds held by the Library. Listen to Nature can be browsed by location, animal type, or habitat. Maps are provided with red dots plotting the locations of recordings; clicking any dot launches a player and the sound file. Alphabetical lists of animal sounds also accompany maps from the region. Visitors are invited to search the Catalogue, in this case the combined catalogue of the British Library Sound Archive, which includes all types of recorded sound. It is best to use the advanced search, limit searches to Wildlife sounds, and look for the "Electronic access" link. On a recent visit we heard loons, wolves, and a whip-poor-will recorded in Canada, enjoying the ability to hear sounds originally captured in North America sent back to us from the UK via the Internet.

Extraction and labeling high-resolution images from PDF documents  

NASA Astrophysics Data System (ADS)

Accuracy of content-based image retrieval is affected by image resolution among other factors. Higher resolution images enable extraction of image features that more accurately represent the image content. In order to improve the relevance of search results for our biomedical image search engine, Open-I, we have developed techniques to extract and label high-resolution versions of figures from biomedical articles supplied in the PDF format. Open-I uses the open-access subset of biomedical articles from the PubMed Central repository hosted by the National Library of Medicine. Articles are available in XML and in publisher supplied PDF formats. As these PDF documents contain little or no meta-data to identify the embedded images, the task includes labeling images according to their figure number in the article after they have been successfully extracted. For this purpose we use the labeled small size images provided with the XML web version of the article. This paper describes the image extraction process and two alternative approaches to perform image labeling that measure the similarity between two images based upon the image intensity projection on the coordinate axes and similarity based upon the normalized cross-correlation between the intensities of two images. Using image identification based on image intensity projection, we were able to achieve a precision of 92.84% and a recall of 82.18% in labeling of the extracted images.

Search of the correspondence between the control points for registration of projectively deformed images  

Microsoft Academic Search

The algorithm for search of the correspondence between the points from two planar finite point sets is presented. The protective transformation between the point sets is supposed, but points without correspondence in the other set can be presented in both sets. The algorithm is based on the comparison of two projective and permutation invariants of five-tuples of the points. The

Jewish National and University Library Kettubot Database  

NSDL National Science Digital Library

"For over 2000 years Jewish law has required that every husband present his wife, at the time of their marriage, with a marriage contract or ketubbah, guaranteeing the wife's financial rights in case of the husband's death or divorce." These Kettubot are a rich source for studying Jewish history, customs, and art, as many were decorated according to the locality and period and reflected local customs. In addition, each was a legal document with exact dates and place names, allowing historians to identify them precisely in time and place. The Jewish National and University Library (JNUL) has the largest collection of Kettubot in the world, with over 1,200 items. They have now created an online database of these documents, allowing scholars and others worldwide to access images and bibliographic information. Visitors may browse the collection by country or search by keyword. Images of the Kettubot are available in three resolutions, and bibliographic records include title, place, country, year, material, and size. The names of the parties to the contract and witnesses are also listed, but they appear to be in Hebrew, and users will need the appropriate language capability in their browsers.

Can horizontally oriented breast tomosynthesis image volumes or the use of a systematic search strategy improve interpretation? An eye tracking and free response human observer study  

NASA Astrophysics Data System (ADS)

Our aim was to evaluate if there is a benefit in diagnostic accuracy and efficiency of viewing breast tomosynthesis (BT) image volumes presented horizontally oriented, but also to evaluate the use of a systematic search strategy where the breast is divided, and analyzed consecutively, into two sections. These image presentations were compared to regular vertical image presentation. All methods were investigated using viewing procedures consisting of free scroll volume browsing, and a combination of initial cine loops at three different frame rates (9, 14, 25 fps) terminated upon request followed by free scroll volume browsing if needed. Fifty-five normal BT image volumes in MLO view were collected. In these, simulated lesions (20 masses and 20 clusters of microcalcifications) were randomly inserted, creating four unique image sets for each procedure. Four readers interpreted the cases in a random order. Their task was to locate the lesions, mark and assign a five level confidence scale. The diagnostic accuracy was analyzed using Jackknife Free Receiver Operating Characteristics (JAFROC). Time efficiency and visual search behavior were also investigated using eye tracking. Results indicate there was no statistically significant difference in JAFROC FOM between the different image presentations, although visual search was more time efficient when viewing horizontally oriented image volumes in medium cine loops.

Advanced image collection, information extraction, and change detection in support of NN-20 broad area search and analysis  

SciTech Connect

This report describes the work performed at the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy`s Office of Nonproliferation and National Security, Office of Research and Development (NN-20). The work supports the NN-20 Broad Area Search and Analysis, a program initiated by NN-20 to improve the detection and classification of undeclared weapons facilities. Ongoing PNNL research activities are described in three main components: image collection, information processing, and change analysis. The Multispectral Airborne Imaging System, which was developed to collect georeferenced imagery in the visible through infrared regions of the spectrum, and flown on a light aircraft platform, will supply current land use conditions. The image information extraction software (dynamic clustering and end-member extraction) uses imagery, like the multispectral data collected by the PNNL multispectral system, to efficiently generate landcover information. The advanced change detection uses a priori (benchmark) information, current landcover conditions, and user-supplied rules to rank suspect areas by probable risk of undeclared facilities or proliferation activities. These components, both separately and combined, provide important tools for improving the detection of undeclared facilities.

In search of optimal fear inducing stimuli: Differential behavioral responses to computer animated images in zebrafish  

PubMed Central

Zebrafish has been gaining popularity in behavioral genetics and behavioral neuroscience as this species offers an excellent compromise between system complexity and practical simplicity for mechanistic analyses of brain and behavior function. Recently, a number of studies started to investigate methods with which fear responses may be induced reliably in zebrafish. The ultimate goal of these studies has been to develop zebrafish models of pathological processes and to investigate the mechanisms of fear and to eventually translate the findings to the human clinic. Previously, animated image of a sympatric predator of zebrafish was shown to induce fear responses. Here we expand on this recently gained knowledge and investigate whether other moving images may induce more robust fear responses. The images investigated include the original sympatric predator, the Indian leaf fish, another sympatric predator, the needle fish, a bird silhouette moved on the side or above the tank, an expanding dot mimicking rapid approach of an object shown on the side and from above the tank, as well as non-fear inducing images including a single and a group of zebrafish. Our results indicate that although the sympatric predators do induce some fear responses, the other images, particularly the expanding dot but also the bird silhouette shown from above are more effective. The results also reveal a stimulus dependent motor pattern response repertoire of zebrafish demonstrating that perhaps univariate quantification methods may not be appropriate for uncovering the complexity of fear or anxiety related phenotypical changes in this species.

Use of ERTS-1 images in the search for porphyry copper deposits in Pakistani Baluchistan  

NASA Technical Reports Server (NTRS)

Geomorphic features related to a known porphyry copper deposit at Saindak, western Chagai District, Pakistan, are easily distinguished on ERTS-1 images. New geologic information from the images was used in conjunction with known geology to evaluate one previously known prospect area and to suggest two additional ones, but no new prospects were recognized on the basis of the images alone. The study also showed that Saindak-type deposits are not likely to be present in some extensive areas of the Chagai District. The Saindak deposit is in an area of relatively easily eroded folded sedimentary and volcanic rocks. The deposit is characterized by an elongate zone of easily eroded sulfide-rich rock surrounded by this rim and the central sulfide-rich valley are conspicuous features on the images. Swarms of dikes are probably useful for distinguishing real rims from other resistant rock types, but there is no expression of them on the image, although they are easily seen on aerial photographs of the Saindak rim.

Library of Congress Finding Aids  

NSDL National Science Digital Library

The Encoded Archival Description Working Group at the Library of Congress has announced the first release of a search system for archival finding aids at the LOC. These finding aids are extremely useful to researchers because they offer more detailed information on primary source material than standard catalog records, often providing "information about a collection's provenance and the conditions under which it may be accessed or copied; biographical or organizational histories related to the collection; a note describing the scope and content of the collection; and progressively detailed descriptions of the parts or components of the collection together with the corresponding call numbers [or] container numbers." The aids have been encoded in SGML using Encoded Archival Description (EAD), and search returns are available in both HTML and SGML. Users can search by keyword or browse by subject, name, collection title, or collections by date.

Public Libraries and the Internet 2000  

NSDL National Science Digital Library

In late September 2000, the US National Commission on Libraries and Information Science published results of its sixth public library Internet study released in the last decade (see the September 6, 1996 Scout Report for information about the 1996 survey). The 2000 Internet Connectivity Study measured the level of connectivity, public access, training support, and technology funding, current and anticipated, for staff and the public. Internet connectivity in public libraries is 95.7 percent, up from 83.6 percent reported in the 1998 study. Suburban libraries, according to the data, showed the largest increase in Internet hook-up, with a 20 percent increase since 1998. "Summary data is also available on the prevalence of acceptable use policies, installation of filtering software in libraries when searching the Internet, and use by the public of Internet-accessible resources including commercially produced databases." The US National Commission on Libraries and Information Science is a permanent, independent agency of the federal government charged by law to assess current library and information resources and services and to advise the President and Congress on library policy.

A Search for Radio Transients in Very Large Array Archival Images of the 3C 286 Field  

NASA Astrophysics Data System (ADS)

We present a search for radio transients (RTs) in the field of the bright radio source 3C 286 using archival observations from the Very Large Array (VLA). These observations span 23 years and include 1852 epochs at 1.4 GHz in the C and D configurations. We find no transients in the field. The sensitivity of the observations is limited by dynamic range effects in the images. At large flux densities (>0.2 Jy), single-epoch observations provide a strong limit on the transient surface density. At flux densities near the dynamic range threshold, we use the requirement that transient sources must appear in consecutive epochs to be confirmed as real. This sets the sensitivity at low flux densities to transient durations of ? ~ 1 day, while ?>1 minute for high flux densities. At 70 mJy, we find a 2? limit on the surface density ? < 3 × 10-3 deg-2. At 3 Jy, we find a 2? limit ? < 9 × 10-4 deg-2. A future systematic search of the VLA archives can provide one to two orders of magnitude more sensitivity to RTs.

Millimeter wave radar system on a rotating platform for combined search and track functionality with SAR imaging  

NASA Astrophysics Data System (ADS)

Ground based millimeter wave radar sensors offer the potential for a weather-independent automatic ground surveillance at day and night, e.g. for camp protection applications. The basic principle and the experimental verification of a radar system concept is described, which by means of an extreme off-axis positioning of the antenna(s) combines azimuthal mechanical beam steering with the formation of a circular-arc shaped synthetic aperture (SA). In automatic ground surveillance the function of search and detection of moving ground targets is performed by means of the conventional mechanical scan mode. The rotated antenna structure designed as a small array with two or more RX antenna elements with simultaneous receiver chains allows to instantaneous track multiple moving targets (monopulse principle). The simultaneously operated SAR mode yields areal images of the distribution of stationary scatterers. For ground surveillance application this SAR mode is best suited for identifying possible threats by means of change detection. The feasibility of this concept was tested by means of an experimental radar system comprising of a 94 GHz (W band) FM-CW module with 1 GHz bandwidth and two RX antennas with parallel receiver channels, placed off-axis at a rotating platform. SAR mode and search/track mode were tested during an outdoor measurement campaign. The scenery of two persons walking along a road and partially through forest served as test for the capability to track multiple moving targets. For SAR mode verification an image of the area composed of roads, grassland, woodland and several man-made objects was reconstructed from the measured data.
