  2. 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.

  3. Digital imaging access library

    Cook, Jay F.; Hansen, Mark; Francoise, James J.; Leckie, Robert G.; Smith, Donald V.

    1994-05-01

    The ability to access a vast array of radiological and pathologic diagnoses through computer searches of local medical facility databases is a by-product of the continued development of filmless imaging systems. The Department of Defense (DoD) Medical Diagnostic Imaging Support initiative is expanding through the addition of on-line systems at several DoD health care facilities. Madigan Army Medical Center, as the initial site, will soon be 90% filmless, with over one million images archived. Multiple other DoD medical centers are under installation. The eventual goal is an interconnected network of PACS systems of DoD medical centers and their supported medical facilities throughout the United States. To access this potential pool of medical information requires a centralized database capable of acting as a diagnostic index system. The establishment of a multi-center film library index begins with an initial analysis of issues regarding data storage and access, indexing, cross-coding with pathological files, communication formats, cost sharing, and patient confidentiality. In initiating these first steps to developing this telecommunications library these issues and their implications are discussed. The final implementation of this system will facilitate markedly improved research and teaching capabilities in both radiological and pathological fields.

  14. 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.

  4. National Portrait Gallery Picture Library Search

    NSDL National Science Digital Library

    The (UK) National Portrait Gallery's online portrait database now has a search feature, ideal for all of us who eagerly flip to the back of a book's dust jacket for the author's picture or check a Website's "about" section for images of its creators. The online database contains approximately 10,000 images selected from the million or more portraits of famous Britons in the Gallery's collection. Using simple search, users enter a name and click a radio button indicating whether the person is a portrait artist or sitter. The search returns, however, include links to the work of sitters who are artists as well. For example, searching on John Singer Sargent yields one portrait of the artist and 45 by him. Clicking the radio button for portrait executes a search by title. In advanced search, it is possible to search by profession, such as explorer or food writer, or broader categories of professions, including travel and exploration, education, or literature and writing.

    2011-01-01

    We report on the Gaussian file search system designed as part of the ChemXSeer digital library. Gaussian files are produced by the Gaussian software [4], a software package used for calculating molecular electronic structure and properties. The output files are semi-structured, allowing relatively easy access to the Gaussian attributes and metadata. Our system is currently capable of searching Gaussian documents using a boolean combination of atoms (chemical elements) and attributes. We have also implemented a faceted browsing feature on three important Gaussian attribute types - Basis Set, Job Type and Method Used. The faceted browsing feature enables a user to view and process a smaller, filtered subset of documents.

    Schatz, B R

    1997-01-17

    A digital library enables users to interact effectively with information distributed across a network. These network information systems support search and display of items from organized collections. In the historical evolution of digital libraries, the mechanisms for retrieval of scientific literature have been particularly important. Grand visions in 1960 led first to the development of text search, from bibliographic databases to full-text retrieval. Next, research prototypes catalyzed the rise of document search, from multimedia browsing across local-area networks to distributed search on the Internet. By 2010, the visions will be realized, with concept search enabling semantic retrieval across large collections. PMID:8994022

  11. 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.

  5. Amino acid Alphabet Size in Protein Evolution Experiments: Better to Search a Small library Thoroughly or a Large Library Sparsely?

    PubMed Central

    Muñoz, Enrique

    2015-01-01

    We compare the results obtained from searching a smaller library thoroughly versus searching a more diverse, larger library sparsely. We study protein evolution with reduced amino acid alphabets, by simulating directed evolution experiments at three different alphabet sizes: 20, 5 and 2. We employ a physical model for evolution, the generalized NK model, that has proved successful in modeling protein evolution, antibody evolution, and T cell selection. We find that antibodies with higher affinity are found by searching a library with a larger alphabet sparsely than by searching a smaller library thoroughly, even with well-designed reduced libraries. We find ranked amino acid usage frequencies in agreement with observations of the CDR-H3 variable region of human antibodies. PMID:18375453

    Despite the range of tasks performed by biological image-processing software, current versions cannot find matches for the image in question among the huge range of biological images that exist in the literature and elsewhere on the Internet. Google's Reverse Image Search is designed for this, and it is a simple, yet powerful tool that can be applied to decipher the contents of biological images. For images that contain unfamiliar or unknown elements, for example, Reverse Image Search can identify similar features in published images. Here we describe general guidelines for using this freely available tool to search published images in National Center for Biotechnology Information's (NCBI's) image database. These guidelines can be applied to a variety of types of biological images, including immunohistochemistry and electron microscopy, to facilitate straightforward and rapid searches using Google's Reverse Image Search. © 2015 by John Wiley & Sons, Inc.

Rainier in 1935. Visitors can browse through the entire collection by name, look around by subject heading, or perform a more sophisticated and nuanced search across the entire collection. That's not all, as the site also includes a handy film preservation manual titled "Low-Cost and No-Cost Suggestions To Care For Your Film". On a related note, visitors shouldn't leave the site without viewing a film of a motorcycle race from 1915 and the delightful images of farmers packing the world's largest box of apples in Yakima.

  8. Semantically Enriching the Search System of a Music Digital Library

    NASA Astrophysics Data System (ADS)

    de Juan, Paloma; Iglesias, Carlos

    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.

    NASA Astrophysics Data System (ADS)

    As use of on-line searching services has progressed in libraries, requests on primary materials have increased much more than before. For the purpose of clarifying this trend and countermeasures against it a survey by questionnaire was conducted in 1985. The respondants from totally 112 libraries are as follows ; 60 industrial libraries, 41 academic libraries and 11 libraries of research institutes and laboratories. It was shown that industrial libraries have received more requests on primary materials mostly resulting from on-line searching while the requests have not increased remarkably in academic libraries. Regardless the type of libraries, almost all libraries can not fully meet the requests with their own collection so that industrial libraries have to rely on external information services and academic libraries utilize interlibrary loan system. Requests are sent via on-line from industrial libraries, and by mail from academic libraries. In fact, any-libraries are not likely to review their material-collecting policy. Therefore it is urgent to establish the system which enables use of external information services or interlibrary loan system more than ever.

  13. Substance identification based on transmission THz spectra using library search

    NASA Astrophysics Data System (ADS)

    Platte, Frank; Heise, H. Michael

    2014-09-01

    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.

    Nicholls, Robert A.; Shepherd, John W.; Shepherd, Jean

    1995-09-01

    A set of psychological facial descriptors has been devised to enable computerized searching of criminal photograph albums. The descriptors have been used to encode image databased of up to twelve thousand images. Using a system called FACES, the databases are searched by translating a witness' verbal description into corresponding facial descriptors. Trials of FACES have shown that this coding scheme is more productive and efficient than searching traditional photograph albums. An alternative method of searching the encoded database using a genetic algorithm is currenly being tested. The genetic search method does not require the witness to verbalize a description of the target but merely to indicate a degree of similarity between the target and a limited selection of images from the database. The major drawback of FACES is that is requires a manual encoding of images. Research is being undertaken to automate the process, however, it will require an algorithm which can predict human descriptive values. Alternatives to human derived coding schemes exist using statistical classifications of images. Since databases encoded using statistical classifiers do not have an obvious direct mapping to human derived descriptors, a search method which does not require the entry of human descriptors is required. A genetic search algorithm is being tested for such a purpose.

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

    2015-01-01

    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.

    2012-01-01

    Spectral libraries have emerged as a viable alternative to protein sequence databases for peptide identification. These libraries contain previously detected peptide sequences and their corresponding tandem mass spectra (MS/MS). Search engines can then identify peptides by comparing experimental MS/MS scans to those in the library. Many of these algorithms employ the dot product score for measuring the quality of a spectrum-spectrum match (SSM). This scoring system does not offer a clear statistical interpretation and ignores fragment ion m/z discrepancies in the scoring. We developed a new spectral library search engine, Pepitome, which employs statistical systems for scoring SSMs. Pepitome outperformed the leading library search tool, SpectraST, when analyzing data sets acquired on three different mass spectrometry platforms. We characterized the reliability of spectral library searches by confirming shotgun proteomics identifications through RNA-Seq data. Applying spectral library and database searches on the same sample revealed their complementary nature. Pepitome identifications enabled the automation of quality analysis and quality control (QA/QC) for shotgun proteomics data acquisition pipelines. PMID:22217208

    2001-12-01

    The Scripps Institution of Oceanography, the UCSD Libraries and the San Diego Supercomputing Center have joined forces to establish a digital library for accessing a wide range of multibeam and marine geophysical data, to a community that ranges from the MGG researcher to K-12 outreach clients. This digital library collection will include 233 multibeam cruises with grids, plots, photographs, station data, technical reports, planning documents and publications, drawn from the holdings of the Geological Data Center and the SIO Archives. Inquiries will be made through an Ocean Exploration Console, reminiscent of a cockpit display where a multitude of data may be displayed individually or in two or three-dimensional projections. These displays will provide access to cruise data as well as global databases such as Global Topography, crustal age, and sediment thickness, thus meeting the day-to-day needs of researchers as well as educators, students, and the public. The prototype contains a few selected expeditions, and a review of the initial approach will be solicited from the user community during the poster session. The search process can be focused by a variety of constraints: geospatial (lat-lon box), temporal (e.g., since 1996), keyword (e.g., cruise, place name, PI, etc.), or expert-level (e.g., K-6 or researcher). The Storage Resource Broker (SRB) software from the SDSC manages the evolving collection as a series of distributed but related archives in various media, from shipboard data through processing and final archiving. The latest version of MB-System provides for the systematic creation of standard metadata, and for the harvesting of metadata from multibeam files. Automated scripts will be used to load the metadata catalog to enable queries with an Oracle database management system. These new efforts to bridge the gap between libraries and data archives are supported by the NSF Information Technology and National Science Digital Library (NSDL) programs, augmented by UC funds, and closely coordinated with Digital Library for Earth System Education (DLESE) activities.

  4. Histology image search using multimodal fusion.

    PubMed

    Caicedo, Juan C; Vanegas, Jorge A; Páez, Fabian; González, Fabio A

    2014-10-01

    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.

    Being able to detect distinguishable objects is a key component in many high level computer vision applications. Traditional methods for building such detectors require a large amount of carefully collected and cleaned data. For example to build a face detector, a large number of face images need to be collected and faces in each image need to be cropped and aligned as the data for training. This process is tedious and error-pruning. Recently more and more people are sharing their photos on the internet, if we could leverage these data for building a detector, it will save tremendous amount of effort in collecting training data. Popular internet search engines and community photo websites like Google image search, Picassa, Flickr make it possible to harvesting online images for image understanding tasks. In this paper, we develop a method leveraging images obtained from online image search to build an object detector. The proposed method can automatically identify the most distinguishable features across the downloaded images. Using these learned features, a detector can be built to detect the object in a new image. Experiments show promising results of our approach.

    Foust, Jill E.; Bergen, Phillip; Maxeiner, Gretchen L.; Pawlowski, Peter N.

    2007-01-01

    Purpose: This paper reports on the development of a tool for searching the contents of licensed full-text electronic book (e-book) collections. Setting: The Health Sciences Library System (HSLS) provides services to the University of Pittsburgh's medical programs and large academic health system. Brief Description: The HSLS has developed an innovative tool for federated searching of its e-book collections. Built using the XML-based Vivísimo development environment, the tool enables a user to perform a full-text search of over 2,500 titles from the library's seven most highly used e-book collections. From a single “Google-style” query, results are returned as an integrated set of links pointing directly to relevant sections of the full text. Results are also grouped into categories that enable more precise retrieval without reformulation of the search. Results/Evaluation: A heuristic evaluation demonstrated the usability of the tool and a web server log analysis indicated an acceptable level of usage. Based on its success, there are plans to increase the number of online book collections searched. Conclusion: This library's first foray into federated searching has produced an effective tool for searching across large collections of full-text e-books and has provided a good foundation for the development of other library-based federated searching products.

  13. QuickMod: A tool for open modification spectrum library searches.

    2011-07-01

    MS2 library spectra are rich in reproducible information about peptide fragmentation patterns compared to theoretical spectra modeled by a sequence search tool. So far, spectrum library searches are mostly applied to detect peptides as they are present in the library. However, they also allow finding modified variants of the library peptides if the search is done with a large precursor mass window and an adapted Spectrum-Spectrum Match (SSM) scoring algorithm. We perform a thorough evaluation on the use of library spectra as opposed to theoretical peptide spectra for the identification of PTMs, analyzing spectra of a well-annotated modification-rich test data set compiled from public data repositories. These initial studies motivate the development of our modification tolerant spectrum library search tool QuickMod, designed to identify modified variants of the peptides listed in the spectrum library without any prior input from the user estimating the modifications present in the sample. We built the search algorithm of QuickMod after carefully testing different SSM similarity scores. The final spectrum scoring scheme uses a support vector machine (SVM) on a selection of scoring features to classify correct and incorrect SSM. After identification of a list of modified peptides at a given False Discovery Rate (FDR), the modifications need to be positioned on the peptide sequence. We present a rapid modification site assignment algorithm and evaluate its positioning accuracy. Finally, we demonstrate that QuickMod performs favorably in terms of speed and identification rate when compared to other software solutions for PTM analysis. PMID:21500769

    1996-03-01

    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.

    Mass spectrometry-based proteomics is a maturing discipline of biologic research that is experiencing substantial growth. Instrumentation has steadily improved over time with the advent of faster and more sensitive instruments collecting ever larger data files. Consequently, the computational process of matching a peptide fragmentation pattern to its sequence, traditionally accomplished by sequence database searching and more recently also by spectral library searching, has become a bottleneck in many mass spectrometry experiments. In both of these methods, the main rate limiting step is the comparison of an acquired spectrum with all potential matches from a spectral library or sequence database. This is a highly parallelizable process because the core computational element can be represented as a simple but arithmetically intense multiplication of two vectors. In this paper we present a proof of concept project taking advantage of the massively parallel computing available on graphics processing units (GPUs) to distribute and accelerate the process of spectral assignment using spectral library searching. This program, which we have named FastPaSS (for Fast Parallelized Spectral Searching) is implemented in CUDA (Compute Unified Device Architecture) from NVIDIA which allows direct access to the processors in an NVIDIA GPU. Our efforts demonstrate the feasibility of GPU computing for spectral assignment, through implementation of the validated spectral searching algorithm SpectraST in the CUDA environment.

    2007-11-15

    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.

  4. Java Library for Input and Output of Image Data and Metadata

    2003-01-01

    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.

  8. Searching for patterns in remote sensing image databases using neural networks

    NASA Technical Reports Server (NTRS)

    Paola, Justin D.; Schowengerdt, Robert A.

    1995-01-01

    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.

    The experiments reported here were designed to test the suggestion of many researchers that selective attention to visual features of a prey can account for search-image effects. In 3 experiments pigeons ate wheat and vetch grains presented on multicolored and gray gravel trays. In Experiment 1 search-image effects were evident when grains were cryptic but not when they were conspicuous.

    The suitability of Hyperion, the first civilian hyperspectral sensor in space, for mapping coral reef benthic substrates has been investigated in this study. An image of Cairns Reef, in the northern section of the Australian Great Barrier Reef (GBR), was acquired during Hyperion Calibration and Validation activities. A field experiment was carried out on Cairns Reef to collect information about the optical properties of the water in the area and to map benthic cover by means of video transects. An approach was used to classify the Hyperion image that allows convenient mapping of benthic substrate type and water depth simultaneously. A hyperspectral library of radiance at Hyperion altitude was simulated using a spectral library of GBR benthic substrates, a Hydrolight 4.1 radiative transfer model, and an in-house atmospheric model similar to Modtran-3.7. The image was then classified using the Hyperion at-sensor radiance data and the Spectral Angle Mapper metric using the simulated at-sensor spectral library. The results suggest that using spectral libraries created with forward modelling from the sea bottom to top of the atmosphere are useful tools for interpretation of reefs and can give better results in image classification than classifying the image after removing atmospheric and water column effects. The results also suggest that bottom type and water depth can be separated and mapped simultaneously provided hyperspectral data is available.

  15. WISE: a content-based Web image search engine

    2000-12-01

    This paper describes the development of a prototype of a Web Image Search Engine (WISE), which allows users to search for images on the WWW by image examples, in a similar fashion to current search engines that allow users to find related Web pages using text matching on keywords. The system takes an image specified by the user and finds similar images available on the WWW by comparing the image contents using low level image features. The current version of the WISE system consists of a graphical user interface (GUI), an autonomous Web agent, an image comparison program and a query processing program. The users specify the URL of a target image and the URL of the starting Web page from where the program will 'crawl' the Web, finding images along the way and retrieve those satisfying a certain constraints. The program then computes the visual features of the retrieved images and performs content-based comparison with the target image. The results of the comparison are then sorted according to a certain similarity measure, which along with thumbnails and information associated with the images, such as the URLs; image size, etc. are then written to an HTML page. The resultant page is stored on a Web server and is outputted onto the user's Web browser once the search process is complete. A unique feature of the current version of WISE is its image content comparison algorithm. It is based on the comparison of image palettes and it therefore very efficient in retrieving one of the two universally accepted image formats on the Web, 'gif.' In gif images, the color palette is contained in its header and therefore it is only necessary to retrieve the header information rather than the whole images, thus making it very efficient.

  19. Multiview alignment hashing for efficient image search.

    PubMed

    Liu, Li; Yu, Mengyang; Shao, Ling

    2015-03-01

    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.

    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.

  6. 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.

Image processing, pattern recognition and computer vision are important branches of science and apply to tasks ranging from critical, involving medical diagnostics, to everyday tasks including art and entertainment purposes. It is therefore crucial to provide students of image processing and pattern recognition with the most up-to-date solutions available. In the Institute of Electronics at the Technical University of Lodz we facilitate the teaching process in this subject with the OpenCV library, which is an open-source set of classes, functions and procedures that can be used in programming efficient and innovative algorithms for various purposes. The topics of student projects completed with the help of the OpenCV library range from automatic correction of image quality parameters or creation of panoramic images from video to pedestrian tracking in surveillance camera video sequences or head-movement-based mouse cursor control for the motorically impaired.

    Users of digital image libraries are often not interested in image data per se but in derived products such as catalogs of objects of interest. Converting an image database into a usable catalog is typically carried out manually at present. For many larger image databases the purely manual approach is completely impractical. In this paper we describe the development of a trainable cataloging system: the user indicates the location of the objects of interest for a number of training images and the system learns to detect and catalog these objects in the rest of the database. In particular we describe the application of this system to the cataloging of small volcanoes in radar images of Venus. The volcano problem is of interest because of the scale (30,000 images, order of 1 million detectable volcanoes), technical difficulty (the variability of the volcanoes in appearance) and the scientific importance of the problem. The problem of uncertain or subjective ground truth is of fundamental importance in cataloging problems of this nature and is discussed in some detail. Experimental results are presented which quantify and compare the detection performance of the system relative to human detection performance. The paper concludes by discussing the limitations of the proposed system and the lessons learned of general relevance to the development of digital image libraries.

    Recent neural signal decoding studies based on functional magnetic resonance imaging (fMRI) have identified the specific image presenting to the subject from a set of potential images, and some studies extend neural decoding into image reconstruction, i.e. image contents that the subject perceived were decoded from the fMRI signals recorded during the subject looking at images. In this paper, we decoded the target images using fMRI signals and described a target image searching method based on the relationship between target image stimuli and fMRI activity. We recorded fMRI data during a serial visual stimuli image presentation task, some of the stimuli images were target images and the rest images were non-target ones. Our fMRI data analysis results showed that in the serial visual presentation task, target images elicited a stereotypical response in the fMRI, which can be detected by multi-voxel pattern analysis (MVPA). Classifiers designed with support vector machine (SVM) used this response to decipher target images from non-target images. The leave-one-run-out cross-validation showed that we can pick out the target images with a possibility far above the chance level, which indicate that there's a neural signatures correlated with the target image recognition process in the human systems.

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

    NASA Astrophysics Data System (ADS)

    Zhang, Yan; Ning, Ruola; Conover, David

    2008-03-01

    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.

    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

  2. Water spectral libraries for the interpretation of image spectrometric data

    1993-09-01

    This paper reports the assessment of water reflectance spectra measured under controlled condition for analysis of the imaging spectrometry data of inland waters. The application of imaging spectrometry to the study of inland waters depends on a better understanding of the optical properties of the water components. To increase this understanding, a collection of water spectra has been measured under laboratory and ground control conditions as a part of an EOS interdisciplinary investigation. The radiometric measurement derived from those experiments is known as the Bidirectional Reflectance Function (BRDF). R was simulated using variations of a model derived from the two stream approximation of the radiative transfer equation (RTE) and compared to the BRDF. BRDF was also measured 'in situ' from a boat based spectrometer (BoaR) and from an helicopter based spectrometer (HeIR). Modelled R (MoIR), laboratory measured (BRDF) (LabR) and ground measured BRDF (BoaR and HeIR) were compared. They were also used to unmix the spectra of two different aquatic systems. Preliminary results show that at low chlorophyll and gilvin concentration, there is a good agreement between ModR and LabR, regardless of the model variation used. For both low and high inorganic matter concentration, the agreement between ModR and LabR is poor. All sets of data present the main features which characterize the high chlorophyll concentration reflectance spectra, but the amount of reflectance displayed by LabR and ModR is 50 times smaller than that measured in situ. When the different sets are used as input to unmixing algorithms they also yield different results.

    1983-11-01

    The Cataloging Distribution Service (CDS) of the Library of Congress working with Xerox Electro-Optical Systems, Inc. of Pasadena, California has succeeded in developing and implementing one of the first image processing document delivery systems in the world using optical disk storage technology. The system uses automated file management and demand printing capability to replace a very costly, labor intensive, manual operation. The system includes a high resolution 480 bpi laser scanner, high capacity (4.5 gigabytes/surface) optical disk storage and a high resolution (480 bpi) laser printer. Through the implementa-tion of this system the Library of Congress has shown initiative and leadership, and has demonstrated that the automated systems of the future will process not only character code data but imaginal data in an attempt to move away from paper as a means of transmitting information.

    Niblack, W.

    1981-01-01

    The Earth Resources Observation System (EROS) Data Center in Sioux Falls, South Dakota distributes precision corrected Landsat MSS and RBV data. These data are derived from master data tapes produced by the Master Data Processor (MDP), NASA's system for computing and applying corrections to the data. Included in the MDP is the Control Point Library Building System (CPLBS), an interactive, menu-driven system which permits a user to build and maintain libraries of control points. The control points are required to achieve the high geometric accuracy desired in the output MSS and RBV data. This paper describes the processing performed by CPLBS, the accuracy of the system, and the host computer and special image viewing equipment employed.

    NSDL National Science Digital Library

    Lousiana State University's Digital Library, in partnership with the Ogden Museum of Southern Art and the Louisiana State Museum, makes two image databases available: The Preservation of Louisiana's Treasures Program, about 200 images of Southern fine art, primarily 20th-century paintings and photographs from the Roger Houston Ogden collection; and the Rowles Stereograph Collection, 386 stereographs, "vintage albumen prints of New Orleans and Louisiana . . . from mid 1860s to the early 20th century." There are some surprisingly modern images in the stereograph collection, such as a 1978 Karem Abdul Jabbar slam dunk, and a 1930 stereograph portrait of Huey Long. The search interface for both databases is the same, allowing keyword searches or browsing by titles, creators, or subjects. In the browse mode, images are presented as pages of five thumbnails. This simple arrangement is missing some navigational tools; when browsing, there is no way to get back to the beginning without hitting the back button repeatedly; after search results are displayed, it is difficult to do a new search without going all the way back to the LSU Digital Library homepage.

    PubMed

    2007-09-01

    A widely used approach to image registration involves finding the general linear transformation that maximizes the mutual information between two images, with the transformation being rigid-body [i.e., belonging to SE(3)] or volume-preserving [i.e., belonging to SL(3)]. In this paper, we present coordinate-invariant, geometric versions of the Nelder-Mead optimization algorithm on the groups SL(3), SE(3), and their various subgroups, that are applicable to a wide class of image registration problems. Because the algorithms respect the geometric structure of the underlying groups, they are numerically more stable, and exhibit better convergence properties than existing local coordinate-based algorithms. Experimental results demonstrate the improved convergence properties of our geometric algorithms. PMID:17784595

  19. Oriented modulation for watermarking in direct binary search halftone images.

    PubMed

    Guo, Jing-Ming; Su, Chang-Cheng; Liu, Yun-Fu; Lee, Hua; Lee, Jiann-Der

    2012-09-01

    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.

  20. PIXTOOLS - 13 PROGRAMS AND A LIBRARY THAT OPERATE ON BITMAP IMAGE FILES

    NASA Technical Reports Server (NTRS)

    Choi, D.

    1994-01-01

    PIXTOOLS is a package for the Silicon Graphics IRIS consisting of thirteen programs plus a library for operating on bitmap images. The image data structure is referred to as a PIXIMAGE. The programs allow the IRIS user to create and edit, perform screen saves, resize, and capture high-resolution images from the Sharp JX450 scanner. Images can be output to the QMS laser printer, the Tektronix 4693 color thermal printer, and the Matrix QCRZ film recorder. Additionally, PIX format images can be converted to SGI image format (and vice versa) or converted to PostScript format. PIX or SGI format images can be converted to ".ras" files which can be read by the "rasp" routine in the PLOT3D/AMES program (available from COSMIC), and ".ras" files can be converted to PIX files. Eleven of the programs print information and read and write files while two, PIXSCAN and PIXEDIT, offer graphical interfaces. PIXEDIT uses the full IRIS screen as a drawing area and pop-up menus are available. The menus allow manipulation of images and background color, and saving the screen to a file. PIXSCAN is the user interface to the Sharp JX450 scanner. This program allows the user to do a preliminary scan of an image at low resolution, and then select an area to rescan in higher resolution into a file. PIXSCAN requires the user to have the "gpib" (IEEE 488) board and "libgpib.a" library from Silicon Graphics, Inc. User instructions for all the programs are provided in the form of UNIX on-line manual pages. The PIXTOOLS programs are written in C-Language for execution on SGI IRIS 4D series workstations running IRIX 3.2 or later. PIXEDIT (the largest program) requires 840K of main memory. The programs with graphical interfaces require that the IRIS have at least 24 bit planes. The program package is available on a .25 inch streaming magnetic tape cartridge in UNIX tar format. A README file and UNIX man pages provide information regarding installation and use of the PIXTOOLS programs. A nine-page manual which provides slightly more detailed information may be purchased separately. PIXTOOLS was developed in 1990 and updated in 1991.

    We discuss a simple search problem which can be pursued with different methods, either on a classical or on a quantum basis. The system is represented by a chain of trapped ions. The ion to be searched for is a member of that chain, consisting, however, of an isotopic species different from the others. It is shown that classical imaging may lead to the final result as fast as quantum imaging. However, for the discussed case the quantum method gives more flexibility and higher precision when the number of ions considered in the chain increases. In addition, interferences are observable even when the distances between the ions are smaller than half a wavelength of the incident light.

  4. Full Elastic Waveform Search Engine for Near Surface Imaging

    NASA Astrophysics Data System (ADS)

    Zhang, J.; Zhang, X.

    2014-12-01

    For processing land seismic data, the near-surface problem is often very complex and may severely affect our capability to image the subsurface. The current state-of-the-art technology for near surface imaging is the early arrival waveform inversion that solves an acoustic wave-equation problem. However, fitting land seismic data with acoustic wavefield is sometimes invalid. On the other hand, performing elastic waveform inversion is very time-consuming. Similar to a web search engine, we develop a full elastic waveform search engine that includes a large database with synthetic elastic waveforms accounting for a wide range of interval velocity models in the CMP domain. With each CMP gather of real data as an entry, the search engine applies Multiple-Randomized K-Dimensional (MRKD) tree method to find approximate best matches to the entry in about a second. Interpolation of the velocity models at CMP positions creates 2D or 3D Vp, Vs, and density models for the near surface area. The method does not just return one solution; it gives a series of best matches in a solution space. Therefore, the results can help us to examine the resolution and nonuniqueness of the final solution. Further, this full waveform search method can avoid the issues of initial model and cycle skipping that the method of full waveform inversion is difficult to deal with.

    The Image Content Engine (ICE) is being developed to provide cueing assistance to human image analysts faced with increasingly large and intractable amounts of image data. The ICE architecture includes user configurable feature extraction pipelines which produce intermediate feature vector and match surface files which can then be accessed by interactive relational queries. Application of the feature extraction algorithms to large collections of images may be extremely time consuming and is launched as a batch job on a Linux cluster. The query interface accesses only the intermediate files and returns candidate hits nearly instantaneously. Queries may be posed for individual objects or collections. The query interface prompts the user for feedback, and applies relevance feedback algorithms to revise the feature vector weighting and focus on relevant search results. Examples of feature extraction and both model-based and search-by-example queries are presented.

    NASA Astrophysics Data System (ADS)

    Kepner, J. V.; Janka, R. S.; Lebak, J.; Richards, M. A.

    1999-12-01

    The Vector/Signal/Image Processing Library (VSIPL) is a DARPA initiated effort made up of industry, government and academic representatives who have defined an industry standard API for vector, signal, and image processing primitives for real-time signal processing on high performance systems. VSIPL supports a wide range of data types (int, float, complex, ...) and layouts (vectors, matrices and tensors) and is ideal for astronomical data processing. The VSIPL API is intended to serve as an open, vendor-neutral, industry standard interface. The object-based VSIPL API abstracts the memory architecture of the underlying machine by using the concept of memory blocks and views. Early experiments with VSIPL code conversions have been carried out by the High Performance Computing Program team at the UCSD. Commercially, several major vendors of signal processors are actively developing implementations. VSIPL has also been explicitly required as part of a recent Rome Labs teraflop procurement. This poster presents the VSIPL API, its functionality and the status of various implementations.

    2013-12-01

    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.

    Within the next few years, several instruments aiming at imaging extrasolar planets will see first light. In parallel, low mass planets are being searched around red dwarfs which offer more favorable conditions, both for radial velocity detection and transit studies, than solar-type stars. We review recent advancements and issues concerning the construction of synthetic spectral libraries for very low mass stars, brown dwarfs and exoplanets. The revised solar oxygen abundances and cloud models allow to reproduce the photometric and spectroscopic properties of this transition to a degree never achieved before, but problems remain in the important M-L transition characteristic of the Teff range of characterizable exoplanets.

  15. Library Literature: Redesigning Library Services: A Manifesto

    NSDL National Science Digital Library

    Buckland, Michael Keeble.

    The Berkeley Digital Library SunSITE (discussed in the February 9, 1996 Scout Report) has added the first in what will be a series of library literature, Michael Buckland's Redesigning Library Services: A Manifesto. Buckland argues against what he sees as library literature's over-emphasis on technology for technology's sake, "on means, rather than on ends, and tactics rather than strategy." Though electronic library management has certainly changed and grown since Redesigning Library Services was first published (1992), the book's primary emphasis on the goals and purposes of library services still serves as a relevant touchstone. Buckland's book is meant to countervail against the fact that "there is so much more written, for example, on how to build collections than on the roles that collections play." The text can be read online, downloaded (.pdf), or searched for keywords (Note that searches return only links to chapters, not passages of text).

    Summary 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

    2013-01-01

    Summary Cytological profiling is a high-content image-based screening technology that provides insight into the mode of action (MOA) for test compounds by directly measuring hundreds of phenotypic cellular features. We have extended this recently reported technology to the mechanistic characterization of unknown natural products libraries for the direct prediction of compound MOAs at the primary screening stage. By analyzing a training set of commercial compounds of known mechanism and comparing these profiles to those obtained from natural product library members, we have successfully annotated extracts based on mode of action, dereplicated known compounds based on biological similarity to the training set, and identified and predicted the MOA of a family of new iron siderophores. Coupled with traditional analytical techniques, cytological profiling provides a new avenue for the creation of ‘function-first’ platforms for natural products discovery. PMID:23438757

    2014-04-01

    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

    2005-01-01

    Background Web-based searching is the accepted contemporary mode of retrieving relevant literature, and retrieving as many full text articles as possible is a typical prerequisite for research success. In most cases only a proportion of references will be directly accessible as digital reprints through displayed links. A large number of references, however, have to be verified in library catalogues and, depending on their availability, are accessible as print holdings or by interlibrary loan request. Methods The problem of verifying local print holdings from an initial retrieval set of citations can be solved using Z39.50, an ANSI protocol for interactively querying library information systems. Numerous systems include Z39.50 interfaces and therefore can process Z39.50 interactive requests. However, the programmed query interaction command structure is non-intuitive and inaccessible to the average biomedical researcher. For the typical user, it is necessary to implement the protocol within a tool that hides and handles Z39.50 syntax, presenting a comfortable user interface. Results PMD2HD is a web tool implementing Z39.50 to provide an appropriately functional and usable interface to integrate into the typical workflow that follows an initial PubMed literature search, providing users with an immediate asset to assist in the most tedious step in literature retrieval, checking for subscription holdings against a local online catalogue. Conclusion PMD2HD can facilitate literature access considerably with respect to the time and cost of manual comparisons of search results with local catalogue holdings. The example presented in this article is related to the library system and collections of the German Cancer Research Centre. However, the PMD2HD software architecture and use of common Z39.50 protocol commands allow for transfer to a broad range of scientific libraries using Z39.50-compatible library information systems.

    2012-01-01

    Purpose To measure natural image search performance in patients with central vision impairment. To evaluate the performance effect for a JPEG based image enhancement technique using the visual search task. Method 150 JPEG images were presented on a touch screen monitor in either an enhanced or original version to 19 patients (visual acuity 0.4 to 1.2 logMAR, 6/15 to 6/90, 20/50 to 20/300) and 7 normally sighted controls (visual acuity ?0.12 to 0.1 logMAR, 6/4.5 to 6/7.5, 20/15 to 20/25). Each image fell into one of three categories: faces, indoors, and collections. The enhancement was realized by moderately boosting a mid-range spatial frequency band in the discrete cosine transform (DCT) coefficients of the image luminance component. Participants pointed to an object in a picture that matched a given target displayed at the upper-left corner of the monitor. Search performance was quantified by the percentage of correct responses, the median search time of correct responses, and an “integrated performance” measure – the area under the curve of cumulative correct response rate over search time. Results Patients were able to perform the search tasks but their performance was substantially worse than the controls. Search performances for the 3 image categories were significantly different (p?0.001) for all the participants, with searching for faces being the most difficult. When search time and correct response were analyzed separately, the effect of enhancement led to increase in one measure but decrease in another for many patients. Using the integrated performance, it was found that search performance declined with decrease in acuity (p=0.005). An improvement with enhancement was found mainly for the patients whose acuity ranged from 0.4 to 0.8 logMAR (6/15 to 6/38, 20/50 to 20/125). Enhancement conferred a small but significant improvement in integrated performance for indoor and collection images (p=0.025) in the patients. Conclusion Search performance for natural images can be measured in patients with impaired vision to evaluate the effect of image enhancement. Patients with moderate vision loss might benefit from the moderate level of enhancement used here. PMID:22540926

    2012-04-01

    In this paper, we propose a new hybrid approach for image segmentation. The proposed approach exploits spatial fuzzy c-means for clustering image pixels into homogeneous regions. In order to improve the performance of fuzzy c-means to cope with segmentation problems, we employ gravitational search algorithm which is inspired by Newton's rule of gravity. Gravitational search algorithm is incorporated into fuzzy c-means to take advantage of its ability to find optimum cluster centers which minimizes the fitness function of fuzzy c-means. Experimental results show effectiveness of the proposed method in segmentation different types of images as compared to classical fuzzy c-means.

    Simultaneous high-resolution full-scan and tandem mass spectrometry (MS/MS) analysis using time of flight mass spectrometry brings an answer for increasing demand of retrospective and non-targeted data analysis. Such analysis combined with spectral library searching is a promising tool for targeted and untargeted screening of small molecules. Despite considerable extension of the panel of compounds of tandem mass spectral libraries, the heterogeneity of spectral data poses a major challenge against the effective usage of spectral libraries. Performance evaluation of available LC-MS/MS libraries will significantly increase credibility in the search results. The present work was aimed to evaluate fluctuation of MS/MS pattern, in the peak intensities distribution together with mass accuracy measurements, and in consequence, performance compliant with ion ratio and mass error criteria as principles in identification processes for targeted and untargeted contaminants at trace levels. Matrix effect and ultra-trace levels of concentration (from 50?ng?l(-1) to 1000?ng?l(-1) were evaluated as potential source of inaccuracy in the performance of spectral matching. Matrix-matched samples and real samples were screened for proof of applicability. By manual review of data and application of ion ratio and ppm error criteria, false negatives were obtained; this number diminished when in-house library was used, while with on-line MS/MS databases 100% of positive samples were found. In our experience, intensity of peaks across spectra was highly correlated to the concentration effect and matrix complexity. In turn, analysis of spectra acquired at trace concentrations and in different matrices results in better performance in providing correct and reliable identification. PMID:25230185

    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.

    An image retrieval system for JET has been developed. The image database contains the images of the JET high speed visible camera. The system input is a pattern selected inside an image and the output is the group of frames (defined by their discharge numbers and time slices) that show patterns similar to the selected one. This approach is based on morphological pattern recognition and it should be emphasized that the pattern is found independently of its location in the frame. The technique encodes images into characters and, therefore, it transforms the pattern search into a character-matching problem.

    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.

    Image enhancement is an important procedure of image processing and analysis. This paper presents a new technique using a modified measure and blending of cuckoo search and particle swarm optimization (CS-PSO) for low contrast images to enhance image adaptively. In this way, contrast enhancement is obtained by global transformation of the input intensities; it employs incomplete Beta function as the transformation function and a novel criterion for measuring image quality considering three factors which are threshold, entropy value, and gray-level probability density of the image. The enhancement process is a nonlinear optimization problem with several constraints. CS-PSO is utilized to maximize the objective fitness criterion in order to enhance the contrast and detail in an image by adapting the parameters of a novel extension to a local enhancement technique. The performance of the proposed method has been compared with other existing techniques such as linear contrast stretching, histogram equalization, and evolutionary computing based image enhancement methods like backtracking search algorithm, differential search algorithm, genetic algorithm, and particle swarm optimization in terms of processing time and image quality. Experimental results demonstrate that the proposed method is robust and adaptive and exhibits the better performance than other methods involved in the paper. PMID:25784928

    • 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.

    We have developed an automated specimen search algorithm for cryo-electron microscopy imaging of ice-embedded single particles suspended across regularly spaced holes. To maximize the particle visibility under a low electron exposure rate condition, specimen searching is carried out in diffraction mode. However, images in diffraction mode contain significant pincushion distortion, making it difficult to computationally predict the locations of the regularly spaced holes. We have implemented a distortion-correction mechanism to restore the primitive distortion-free image and a correlation-based algorithm to accurately determine the periodicity of the holes. A stage-shift method to optimize positional reproducibility is also implemented. Addition of our algorithms to the JADAS software for automated transmission electron microscopy data acquisition has significantly improved the accuracy of specimen search. PMID:20356853

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

    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.

    2013-01-01

    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

  7. Ideal and visual-search observers: accounting for anatomical noise in search tasks with planar nuclear imaging

    NASA Astrophysics Data System (ADS)

    Sen, Anando; Gifford, Howard C.

    2015-03-01

    Model observers have frequently been used for hardware optimization of imaging systems. For model observers to reliably mimic human performance it is important to account for the sources of variations in the images. Detection-localization tasks are complicated by anatomical noise present in the images. Several scanning observers have been proposed for such tasks. The most popular of these, the channelized Hotelling observer (CHO) incorporates anatomical variations through covariance matrices. We propose the visual-search (VS) observer as an alternative to the CHO to account for anatomical noise. The VS observer is a two-step process which first identifies suspicious tumor candidates and then performs a detailed analysis on them. The identification of suspicious candidates (search) implicitly accounts for anatomical noise. In this study we present a comparison of these two observers with human observers. The application considered is collimator optimization for planar nuclear imaging. Both observers show similar trends in performance with the VS observer slightly closer to human performance.

    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

    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.

    NASA Astrophysics Data System (ADS)

    Mink, Douglas J.

    For five years, WCSTools has provided image astrometry for astronomers who need accurate positions for objects they wish to observe. Other functions have been added and improved since the package was first released. Support has been added for new catalogs, such as the GSC-ACT, 2MASS Point Source Catalog, and GSC II, as they have been published. A simple command line interface can search any supported catalog, returning information in several standard formats, whether the catalog is on a local disk or searchable over the World Wide Web. The catalog searching routine can be located on either end (or both ends!) of such a web connection, and the output from one catalog search can be used as the input to another search.

  2. Cross-indexing of binary SIFT codes for large-scale image search.

    PubMed

    Liu, Zhen; Li, Houqiang; Zhang, Liyan; Zhou, Wengang; Tian, Qi

    2014-05-01

    In recent years, there has been growing interest in mapping visual features into compact binary codes for applications on large-scale image collections. Encoding high-dimensional data as compact binary codes reduces the memory cost for storage. Besides, it benefits the computational efficiency since the computation of similarity can be efficiently measured by Hamming distance. In this paper, we propose a novel flexible scale invariant feature transform (SIFT) binarization (FSB) algorithm for large-scale image search. The FSB algorithm explores the magnitude patterns of SIFT descriptor. It is unsupervised and the generated binary codes are demonstrated to be dispreserving. Besides, we propose a new searching strategy to find target features based on the cross-indexing in the binary SIFT space and original SIFT space. We evaluate our approach on two publicly released data sets. The experiments on large-scale partial duplicate image retrieval system demonstrate the effectiveness and efficiency of the proposed algorithm. PMID:24710404

    This project contributes to the detection of flaws in the germanium detectors for the Cryogenic Dark Matter Search (CDMS) experiment. Specifically, after imaging the detector surface with a precise imaging and measuring device, they developed software to stitch the resulting images together, applying any necessary rotations, offsets, and averaging, to produce a smooth image of the whole detector that can be used to detect flaws on the surface of the detector. These images were also tiled appropriately for the Google Maps API to use as a navigation tool, allowing viewers to smoothly zoom and pan across the detector surface. Automated defect identification can now be implemented, increasing the scalability of the germanium detector fabrication.

  12. Virtual evolution for visual search in natural images results in behavioral receptive fields with inhibitory surrounds.

    PubMed

    Zhang, Sheng; Abbey, Craig K; Eckstein, Miguel P

    2009-01-01

    The neural mechanisms driving perception and saccades during search use information about the target but are also based on an inhibitory surround not present in the target luminance profile (e.g., Eckstein et al., 2007). Here, we ask whether these inhibitory surrounds might reflect a strategy that the brain has adapted to optimize the search for targets in natural scenes. To test this hypothesis, we sought to estimate the best linear template (behavioral receptive field), built from linear combinations of Gabor channels representing V1 simple cells in search for an additive Gaussian target embedded in natural images. Statistically nonstationary and non-Gaussian properties of natural scenes preclude calculation of the best linear template from analytic expressions and require an iterative optimization method such as a virtual evolution via a genetic algorithm. Evolved linear receptive fields built from linear combinations of Gabor functions include substantial inhibitory surround, larger than those found in humans performing target search in white noise. The inhibitory surrounds were robust to changes in the contrast of the signal, generalized to a larger calibrated natural image data set, and tasks in which the signal occluded other objects in the image. We show that channel nonlinearities can have strong effects on the observed linear behavioral receptive field but preserve the inhibitory surrounds. Together, the results suggest that the apparent suboptimality of inhibitory surrounds in human behavioral receptive fields when searching for a target in white noise might reflect a strategy to optimize detection of signals in natural scenes. Finally, we contend that optimized linear detection of spatially compact signals in natural images might be a new possible hypothesis, distinct from decorrelation of visual input and sparse representations (e.g., Graham et al., 2006), to explain the evolution of center-surround organization of receptive fields in early vision.

    We describe the difference imaging pipeline (DiffImg) used to detect transients in deep images from the Dark Energy Survey Supernova program (DES-SN) in its first observing season from Aug 2013 through Feb 2014. DES-SN is a search for transients in which ten 3-deg^2 fields are repeatedly observed in the g,r,i,z passbands with a cadence of about 1 week. The observing strategy has been optimized to measure high-quality light curves and redshifts for thousands of Type Ia supernova (SN Ia) with the goal of measuring dark energy parameters. The essential DiffImg functions are to align each search image to a deep reference image, do a pixel-by-pixel subtraction, and then examine the subtracted image for significant positive detections of point-source objects. The vast majority of detections are subtraction artifacts, but after selection requirements and image filtering with an automated scanning program, there are 130 detections per deg^2 per observation in each band, of which only 25% are artifacts. Of the 7500 tr...

  14. BSIFT: toward data-independent codebook for large scale image search.

    2015-03-01

    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.

    Fast image search with efficient additive kernels and kernel locality-sensitive hashing has been proposed. As to hold the kernel functions, recent work has probed methods to create locality-sensitive hashing, which guarantee our approach's linear time; however existing methods still do not solve the problem of locality-sensitive hashing (LSH) algorithm and indirectly sacrifice the loss in accuracy of search results in order to allow fast queries. To improve the search accuracy, we show how to apply explicit feature maps into the homogeneous kernels, which help in feature transformation and combine it with kernel locality-sensitive hashing. We prove our method on several large datasets and illustrate that it improves the accuracy relative to commonly used methods and make the task of object classification and, content-based retrieval more fast and accurate.

    2007-12-19

    We present a semi-automated method to search for strong galaxy-galaxy lenses in optical imaging surveys. Our search technique constrains the shape of strongly lensed galaxies (or arcs) in a multi-parameter space, which includes the third order (octopole) moments of objects. This method is applied to the Deep Lens Survey (DLS), a deep ground based weak lensing survey imaging to $R\\sim26$. The parameter space of arcs in the DLS is simulated using real galaxies extracted from deep HST fields in order to more accurately reproduce the properties of arcs. Arcs are detected in the DLS using a pixel thresholding method and candidate arcs are selected within this multi-parameter space. Examples of strong galaxy-galaxy lens candidates discovered in the DLS F2 field (4 square degrees) are presented.

    Imaging spectrometers yield rich and informative data products, but interpreting them demands time and expertise. There is a continual need for new algorithms and methods for rapid first-draft analyses to assist analysts during instrument opera-tions. Intelligent data analyses can summarize scenes to draft geologic maps, searching images to direct op-erator attention to key features. This validates data quality while facilitating rapid tactical decision making to select followup targets. Ideally these algorithms would operate in seconds, never grow bored, and be free from observation bias about the kinds of mineral-ogy that will be found.

  4. Performance characteristics of a visual-search human-model observer with sparse PET image data

    Gifford, Howard C.

    2012-02-01

    As predictors of human performance in detection-localization tasks, statistical model observers can have problems with tasks that are primarily limited by target contrast or structural noise. Model observers with a visual-search (VS) framework may provide a more reliable alternative. This framework provides for an initial holistic search that identifies suspicious locations for analysis by a statistical observer. A basic VS observer for emission tomography focuses on hot "blobs" in an image and uses a channelized nonprewhitening (CNPW) observer for analysis. In [1], we investigated this model for a contrast-limited task with SPECT images; herein, a statisticalnoise limited task involving PET images is considered. An LROC study used 2D image slices with liver, lung and soft-tissue tumors. Human and model observers read the images in coronal, sagittal and transverse display formats. The study thus measured the detectability of tumors in a given organ as a function of display format. The model observers were applied under several task variants that tested their response to structural noise both at the organ boundaries alone and over the organs as a whole. As measured by correlation with the human data, the VS observer outperformed the CNPW scanning observer.

    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.

  11. Large Spectral Library Problem

    SciTech Connect

    Chilton, Lawrence K.; Walsh, Stephen J.

    2008-10-03

    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.

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

    PubMed

    Li, Yuenan

    2013-01-10

    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

  15. A novel functional magnetic resonance imaging compatible search-coil eye-tracking system.

    Oeltermann, Axel; Ku, Shih-Pi; Logothetis, Nikos K

    2007-07-01

    Measuring eye movements (EMs) using the search-coil eye-tracking technique is superior to video-based infrared methods [Collewijn H, van der Mark F, Jansen TC. Precise recording of human eye movements. Vision Res 1975;15(3):447-50], which suffer from the instability of pupil size, blinking behavior and lower temporal resolution. However, no conventional functional magnetic resonance imaging (fMRI)-compatible search-coil eye tracker exists. The main problems for such a technique are the interaction between the transmitter coils and the magnetic gradients used for imaging as well as the limited amount of space in a scanner. Here we present an approach to overcome these problems and we demonstrate a method to record EMs in an MRI scanner using a search coil. The system described has a spatial resolution of 0.07 degrees (visual angle) and a high temporal resolution (22 kHz). The transmitter coils are integrated into the visual presentation system and the control/analysis unit is portable, which enables us to integrate the eye tracker with an MRI scanner. Our tests demonstrate low noise in the recorded eye traces and scanning with minimal artifact. Furthermore, the induced current in the search coil caused by the RF pulses does not lead to measurable heating. Altogether, this MR-compatible search-coil eye tracker can be used to precisely monitor EMs with high spatial and temporal resolution during fMRI. It can therefore be of great importance for studies requiring accurate fixation of a target, or measurement and study of the subject's oculomotor system. PMID:17482787

    A search is performed for heavy long-lived charged particles using 3.0 fb$^{-1}$ of pp collisions collected at $\\sqrt{s}$= 7 and 8 TeV with the LHCb detector. The search is mainly based on the response of the ring imaging Cherenkovdetectors to distinguish the heavy, slow-moving particles from muons. No evidence is found for the production of such long-lived states. The results are expressed as limits on the Drell-Yan production of pairs of long-lived particles, with both particles in the LHCb pseudorapidity acceptance, $1.8 < \\eta < 4.9$. The mass-dependent cross-section upper limits are in the range 2-4 fb (at 95\\% CL) for masses between 124 and 309 GeV/c$^2$.

    2007-01-01

    The Darlington Digital Library was created from the first major collection of books, manuscripts, and maps donated to the University of Pittsburgh. The lion's share of the credit for this collection goes to the attorney William M. Darlington, who was born in Pittsburgh in 1815. During his long life, Darlington collected items like John James Audubon's "Birds of America" and hundreds of lithographs, broadsides, and other items. The collection eventually found its way to the university in 1925, and this collection contains over 3,000 items from its holdings. Visitors can scan through the major sections here via the Atlases, Books, Broadsides, and Images areas. The Atlases area includes five gems, including the Novus Orbis Regio, which features North and South America as Simon Gyrnaeus imagined them in 1532. The Broadsides area is a real treat, containing a proclamation by President George Washington declaring February 19, 1795 as a "Day of Public Thanksgiving and Prayer." Finally, users can use the search engine to look for items of particular interest. [KMG

    Recent advances in liquid chromatography/tandem mass spectrometry (LC/MS/MS) technology have provided an opportunity for the development of more specific approaches to achieve the 'screen' and 'confirmation' goals in a single analytical step. For this purpose, this study adapts the electrospray ionization ion trap LC/MS/MS instrumentation (LC/ESI-MS/MS) for the screening and confirmation of over 800 drugs and toxic compounds in biological specimens. Liquid-liquid and solid-phase extraction protocols were coupled to LC/ESI-MS/MS using a 1.8-microm particle size analytical column operated at 50 degrees C. Gradient elution of the analytes was conducted using a solvent system composed of methanol and water containing 0.1% formic acid. Positive-ion ESI-MS/MS spectra and retention times for each of the 800 drugs and toxic compounds were first established using 1-10 microg/mL standard solutions. This spectra and retention time information was then transferred to the library and searched by the identification algorithm for the confirmation of compounds found in test specimens - based on retention time matches and scores of fit, reverse fit, and purity resulting from the searching process. The established method was found highly effective when applied to the analyses of postmortem specimens (blood, urine, and hair) and external proficiency test samples provided by the College of American Pathology (CAP). The development of this approach has significantly improved the efficiency of our routine laboratory operation that was based on a two-step (immunoassay and GC/MS) approach in the past.

    The Internet provides a quick access to a plethora of the medical literature, in the form of journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualized, 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, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Commercial web resources (Medscape, MedConnect, MedicineNet) add to the list of resource databases providing some of their content for open access. Several web-libraries (Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. Availability of specific dermatology-related websites (DermIs, DermNet, and Genamics Jornalseek) is useful addition to the ever growing list of web-based resources. 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 and levels of detail 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.

    A high resolution, handheld imaging sonar system is under development by Teratech Corporation for the U.S. Navy. This is a 192 channel, dual frequency bistatic sonar for Navy divers performing search and survey missions for underwater explosives. Our goal is to provide the most compact and energy efficient imaging system for the divers. The system consists of a self-contained handheld unit and a head mounted display integrated into the divers mask. The low power and small volume are a result of the development of Teratechs Charge Domain Processing (CDP) technology. This technology has led to the development of a low power 64-channel beamformer chip. As a result, only three beamformer chips will be required for the 192 channels. Until now, the implementation of small, low power sonar systems containing this many elements and forming enough beams to create an image was considered impossible. Progress in the development of this product will be presented. In-water testing is planned for late summer 2003. Experimental results and test images available will be presented at the conference.

  15. Lesion search and recognition by thymine DNA glycosylase revealed by single molecule imaging.

    2015-03-11

    The ability of DNA glycosylases to rapidly and efficiently detect lesions among a vast excess of nondamaged DNA bases is vitally important in base excision repair (BER). Here, we use single molecule imaging by atomic force microscopy (AFM) supported by a 2-aminopurine fluorescence base flipping assay to study damage search by human thymine DNA glycosylase (hTDG), which initiates BER of mutagenic and cytotoxic G:T and G:U mispairs in DNA. Our data reveal an equilibrium between two conformational states of hTDG-DNA complexes, assigned as search complex (SC) and interrogation complex (IC), both at target lesions and undamaged DNA sites. Notably, for both hTDG and a second glycosylase, hOGG1, which recognizes structurally different 8-oxoguanine lesions, the conformation of the DNA in the SC mirrors innate structural properties of their respective target sites. In the IC, the DNA is sharply bent, as seen in crystal structures of hTDG lesion recognition complexes, which likely supports the base flipping required for lesion identification. Our results support a potentially general concept of sculpting of glycosylases to their targets, allowing them to exploit the energetic cost of DNA bending for initial lesion sensing, coupled with continuous (extrahelical) base interrogation during lesion search by DNA glycosylases.

    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

    2013-09-27

    We describe the design and phenomenology imaging results of a fully polarimetric W-band millimeter wave (MMW) radiometer developed by Pacific Northwest National Laboratory for wide-area search. Operating from 92 - 94 GHz, the W-band radiometer employs a Dicke switching heterodyne design isolating the horizontal and vertical mm-wave components with 40 dB of polarization isolation. Design results are presented for both infinite conjugate off-axis parabolic and finite conjugate off-axis elliptical fore-optics using optical ray tracing and diffraction calculations. The received linear polarizations are down-converted to a microwave frequency band and recombined in a phase-shifting network to produce all six orthogonal polarization states of light simultaneously, which are used to calculate the Stokes parameters for display and analysis. The resulting system performance produces a heterodyne receiver noise equivalent delta temperature (NEDT) of less than 150m Kelvin. The radiometer provides novel imaging capability by producing all four of the Stokes parameters of light, which are used to create imagery based on the polarization states associated with unique scattering geometries and their interaction with the down welling MMW energy. The polarization states can be exploited in such a way that man-made objects can be located and highlighted in a cluttered scene using methods such as image comparison, color encoding of Stokes parameters, multivariate image analysis, and image fusion with visible and infrared imagery. We also present initial results using a differential imaging approach used to highlight polarization features and reduce common-mode noise. Persistent monitoring of a scene using the polarimetric passive mm-wave technique shows great promise for anomaly detection caused by human activity.

    2010-01-01

    By choosing blood-carrying mosquitoes as prey, Evarcha culicivora, an East African salticid spider, specializes at feeding indirectly on vertebrate blood. It also has an exceptionally complex mate-choice system. An earlier study revealed that search-image use assists E. culicivora in finding prey and mates when restricted to using vision alone. Here we show that search-image use assists E. culicivora in finding prey and mates when restricted to using olfaction alone. After being primed with prey odour or mate odour (control: not primed with odour), spiders were transferred to an olfactometer designed to test ability to find a prey-odour or mate-odour source that was either ‘cryptic’ (i.e. accompanied by a masking odour source, Lantana camara) or ‘conspicuous’ (no L. camara odour). When tested with conspicuous odour, the identity of the priming odour had no significant effect on how many spiders found the odour source. However, when tested with cryptic odour, significantly more spiders found the odour source when primed with congruent odour and significantly fewer spiders found the odour source when primed with incongruent odour.

    We examined SOHO/LASCO (Solar and Heliospheric Observatory/Large Angle Spectroscopic Coronagraph) C3 coronagraph images to search for the long-suspected population of small bodies, the vulcanoids, in heliocentric orbits interior to Mercury. We searched the entire vulcanoid region from 0.07-0.21 AU by visually blinking daily image averages co-registered on background stars. We found no vulcanoids to a moving object detection limiting magnitude of V=8.0, corresponding to objects 20 and 60 km in diameter (assuming Mercury-like albedos) at the inner and outer boundaries of the Vulcanoid Zone, respectively. This negative detection suggests that candidate objects apparently detected interior to 0.09 AU by Courten et al. (1976, Bull. Am. Astron. Soc.8, 504) were not permanent residents of that region, if real at all. Extrapolating from largest objects of 20 and 60 km to smaller-size objects with a Dohnanyi power-law size distribution (1969, J. Geophys. Res.74, 2531), this result implies that the present population of vulcanoids larger than 1 km in diameter is no greater than ˜1800-42000 objects.

    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

  11. A comparison of dense region detectors for image search and fine-grained classification.

    PubMed

    Iscen, Ahmet; Tolias, Giorgos; Gosselin, Philippe-Henri; Jegou, Herve

    2015-08-01

    We consider a pipeline for image classification or search based on coding approaches like bag of words or Fisher vectors. In this context, the most common approach is to extract the image patches regularly in a dense manner on several scales. This paper proposes and evaluates alternative choices to extract patches densely. Beyond simple strategies derived from regular interest region detectors, we propose approaches based on superpixels, edges, and a bank of Zernike filters used as detectors. The different approaches are evaluated on recent image retrieval and fine-grained classification benchmarks. Our results show that the regular dense detector is outperformed by other methods in most situations, leading us to improve the state-of-the-art in comparable setups on standard retrieval and fined-grained benchmarks. As a byproduct of our study, we show that existing methods for blob and superpixel extraction achieve high accuracy if the patches are extracted along the edges and not around the detected regions.

    Accurate segmentation of hip joint cartilage from magnetic resonance (MR) images offers opportunities for quantitative investigations of pathoanatomical conditions such as osteoarthritis. In this paper, we present a fully automatic scheme for the segmentation of the individual femoral and acetabular cartilage plates in the human hip joint from high-resolution 3D MR images. The developed scheme uses an improved optimal multi-object multi-surface graph search framework with an arc-weighted graph representation that incorporates prior morphological knowledge as a basis for segmentation of the individual femoral and acetabular cartilage plates despite weak or incomplete boundary interfaces. This automated scheme was validated against manual segmentations from 3D true fast imaging with steady-state precession (TrueFISP) MR examinations of the right hip joints in 52 asymptomatic volunteers. Compared with expert manual segmentations of the combined, femoral and acetabular cartilage volumes, the automatic scheme obtained mean (± standard deviation) Dice's similarity coefficients of 0.81 (± 0.03), 0.79 (± 0.03) and 0.72 (± 0.05). The corresponding mean absolute volume difference errors were 8.44% (± 6.36), 9.44% (± 7.19) and 9.05% (± 8.02). The mean absolute differences between manual and automated measures of cartilage thickness for femoral and acetabular cartilage plates were 0.13 mm (± 0.12) and 0.11 mm (± 0.11), respectively.

    We describe here our project based in a search for sub-stellar companions (brown dwarfs and exo-planets) around young ultra-cool dwarfs (UCDs) and characterise their properties. We will use current and future technology (high contrast imaging, high-precision Doppler determinations) from the ground and space (VLT, ELT and JWST), to find companions to young objects. Members of young moving groups (MGs) have clear advantages in this field. We compiled a catalogue of young UCD objects and studied their membership to five known young moving groups: Local Association (Pleiades moving group, 20-150 Myr), Ursa Mayor group (Sirius supercluster, 300 Myr), Hyades supercluster (600 Myr), IC 2391 supercluster (35 Myr) and Castor moving group (200 Myr). To assess them as members we used different kinematic and spectroscopic criteria.

    A convenient mass spectrometric approach for the identification of toxicologically relevant compounds in tablets and tablet residues is presented. For comprehensive forensic-toxicological analysis electrospray ionization mass spectrometry was accomplished in positive as well as in negative ion mode on a quadrupole-quadrupole-time-of-flight instrument. Dissolved samples were introduced into the mass spectrometer by flow-injection. Mass spectra as well as tandem mass spectra were acquired. A data-dependent acquisition strategy was used to switch between the mass spectrometric modes. Identification was accomplished via search within a tandem mass spectral library. The applied database contained 8252 spectra collected from 836 compounds in positive ion mode as well as 1023 spectra collected from 103 compounds in negative ion mode. A total of 22 casework samples collected during autopsies from mouth, oesophagus or gastric contents, seized by the police, or found with patients at hospital were screened. Twelve samples contained compounds only detectable in positive ion mode (sildenafil, dihydrocodeine, diphenhydramine, oxprenolol, N-methyl-3,4-methylenedioxyamphetamine, morphine, amphetamine, caffeine, pemoline, orphenadrine, m-chlorphenylpiperazine and tramadol), six samples contained species exclusively detectable in negative ion mode (salicylic acid, acetylsalicylic acid, ibuprofen, ketorolac, valproic acid and phenobarbital), and three samples contained diclofenac detectable in both ionization polarities. One sample did not contain any compound amenable to mass spectrometric analysis. For verification all samples were additionally analyzed by GC/MS. Both methods revealed identical results for all but one sample. The beta-adrenergic blocker oxprenolol was exclusively detected by the flow-injection method. PMID:20097023

  5. Los Angeles Public Library: Electronic Neighborhood

    NSDL National Science Digital Library

    Many urban public library systems across the United States have accumulated large troves of paper ephemera over the years, and the Los Angeles Public Library system is no exception. Funded by a grant from the California State Library, the Fletcher Jones Foundation, and the John Randolph Haynes and Dora Haynes Foundation, the Electronic Neighborhood allows the internet-browsing public access to a number of these documents. The database located here includes a large collection of photographs documenting the city's development, a collection of restaurant menus, and an index to fiction works that take place in and around California. The photo database contains over 2.5 million archival records, and a number of thematic online photo exhibits, including ones that document the 1932 Los Angeles Olympics and golf in Hollywood. The menu database is particularly fascinating, as users can search for a number of restaurant menus from the past century. While not all of the records include scanned menu images, a number of them are already available, such as those from the now-defunct Brown Derby.

  6. A search for debris disks with a dual channel adaptive optics imaging polarimeter

    NASA Astrophysics Data System (ADS)

    Potter, Daniel Edward

    2003-11-01

    A dual channel polarimeter was incorporated into the Hokupa'a adaptive optics system mounted on the Gemini North telescope to enhance sensitivity to detecting the light scattered by circumstellar material. The technique suppressed noise introduced by non-repeatable variations of the point spread function which limit the sensitivity of non-simultaneous adaptive optics imaging. Polarimetric images of the classical T-Tauri star environments around GG Tauri Aab, TW Hydrae, LkCa 15, LkH? 242, GM Aurigae, and SR24 N/S were observed to establish the instrument's sensitivity. A survey of nearby (d < 25 pc), young (age < 1 Gyr), solar-analog stars was undertaken with the polarimeter to search for collisionally active debris disks analogous to our young solar system. Of the 24 stars sampled, none were found to have obvious scattered light signatures. Isotropic and Mie scattering model images of debris disks were used to constrain the amount of material around the survey stars to no more than Mdust ˜ 10-2 MMoon of 1 10?m sized dust contained between 5 50 AU from the sample stars. Particle lifetimes under the influence of the Poynting Robertson Drag, radiation pressure, and solar wind drag are calculated as a function of central star spectral type. The corpuscular drag from stellar winds shorten dust lifetimes by an amount inversely proportional to the stellar wind mass-loss rate. This translates into dust lifetimes 100 1000 times shorter around young solar analog stars compared to the present day. This effect, cam significantly reduce the near-IR detectability of debris disks around these chromospherically active stars.

    1995-01-01

    Designing and building new or renovated space is time consuming and requires politically sensitive discussions concerning a number of both long-term and immediate planning issues. The Medical Library Association's fourth annual survey of library building projects identified ten health sciences libraries that are planning, expanding, or constructing new facilities. Two projects are in predesign stages, four represent new construction, and four involve renovations to existing libraries. The Texas Medical Association Library, the King Faisal Specialist Hospital and Research Centre Library, and the Northwestern University Galter Health Sciences Library illustrate how these libraries are being designed for the future and take into account areas of change produced by new information technologies, curricular trends, and new ways to deliver library services.

    DOE Data Explorer

    The I.M.A.G.E. Consortium was initiated in 1993 by four academic groups on a collaborative basis after informal discussions led to a common vision of how to achieve an important goal in the study of the human genome: the Integrated Molecular Analysis of Genomes and their Expression Consortium's primary goal is to create arrayed cDNA libraries and associated bioinformatics tools, and make them publicly available to the research community. The primary organisms of interest include intensively studied mammalian species, including human, mouse, rat and non-human primate species. The Consortium has also focused on several commonly studied model organisms; as part of this effort it has arrayed cDNAs from zebrafish, and Fugu (pufferfish) as well as Xenopus laevis and X. tropicalis (frog). Utilizing high speed robotics, over nine million individual cDNA clones have been arrayed into 384-well microtiter plates, and sufficient replicas have been created to distribute copies both to sequencing centers and to a network of five distributors located worldwide. The I.M.A.G.E. Consortium represents the world's largest public cDNA collection, and works closely with the National Institutes of Health's Mammalian Gene Collection(MGC) to help it achieve its goal of creating a full-length cDNA clone for every human and mouse gene. I.M.A.G.E. is also a member of the ORFeome Collaboration, working to generate a complete set of expression-ready open reading frame clones representing each human gene. Custom informatics tools have been developed in support of these projects to better allow the research community to select clones of interest and track and collect all data deposited into public databases about those clones and their related sequences. I.M.A.G.E. clones are publicly available, free of any royalties, and may be used by anyone agreeing with the Consortium's guidelines.

    1994-05-01

    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.

    Visual-search (VS) model observers have the potential to provide reliable predictions of human-observer performance in detection-localization tasks. The purpose of this work was to examine some characteristics of human gaze on breast images with the goal of informing the design of our VS observers. Using a helmet-mounted eye- tracking system, we recording the movement of gaze from human observers as they searched for masses in sets of 2D digital breast tomosynthesis (DBT) images. The masses in this study were of a single profile. The DBT images were extracted from image volumes reconstructed with filtered back-projection and penalized maximum- likelihood methods. Fixation times associated with observer points of interest (POIs) were computed from the observer data. The fixation times were then compared to sets of morphological feature values extracted from the images. These features, extracted as cross-correlations involving the mass profile and the test image, included the matched filter (MF), gradient MF, and Laplacian MF. For this initial investigation, we computed correlation coefficients between the fixation times and the feature values.

    2014-08-01

    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.

    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.

    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

  3. Searching for transits in the WTS with the difference imaging light curves

    NASA Astrophysics Data System (ADS)

    Zendejas Dominguez, Jesus

    2013-12-01

    The search for exo-planets is currently one of the most exiting and active topics in astronomy. Small and rocky planets are particularly the subject of intense research, since if they are suitably located from their host star, they may be warm and potentially habitable worlds. On the other hand, the discovery of giant planets in short-period orbits provides important constraints on models that describe planet formation and orbital migration theories. Several projects are dedicated to discover and characterize planets outside of our solar system. Among them, the Wide-Field Camera Transit Survey (WTS) is a pioneer program aimed to search for extra-solar planets, that stands out for its particular aims and methodology. The WTS has been in operation since August 2007 with observations from the United Kingdom Infrared Telescope, and represents the first survey that searches for transiting planets in the near-infrared wavelengths; hence the WTS is designed to discover planets around M-dwarfs. The survey was originally assigned about 200 nights, observing four fields that were selected seasonally (RA = 03, 07, 17 and 19h) during a year. The images from the survey are processed by a data reduction pipeline, which uses aperture photometry to construct the light curves. For the most complete field (19h-1145 epochs) in the survey, we produce an alternative set of light curves by using the method of difference imaging, which is a photometric technique that has shown important advantages when used in crowded fields. A quantitative comparison between the photometric precision achieved with both methods is carried out in this work. We remove systematic effects using the sysrem algorithm, scale the error bars on the light curves, and perform a comparison of the corrected light curves. The results show that the aperture photometry light curves provide slightly better precision for objects with J < 16. However, difference photometry light curves present a significant improvement for fainter stars. In order to detect transits in the WTS light curves, we use a modified version of the box-fitting algorithm. The implementation on the detection algorithm performs a trapezoid-fit to the folded light curve. We show that the new fit is able to produce more accurate results than the box-fit model. We describe a set of selection criteria to search for transit candidates that include a parameter calculated by our detection algorithm: the V-shape parameter, which has proven to be useful to automatically identify and remove eclipsing binaries from the survey. The criteria are optimized using Monte-Carlo simulations of artificial transit signals that are injected into the real WTS light curves and subsequently analyzed by our detection algorithm. We separately optimize the selection criteria for two different sets of light curves, one for F-G-K stars, and another for M-dwarfs. In order to search for transiting planet candidates, the optimized selection criteria are applied to the aperture photometry and difference imaging light curves. In this way, the best 200 transit candidates from a sample of ~ 475 000 sources are automatically selected. A visual inspection of the folded light curves of these detections is carried out to eliminate clear false-positives or false-detections. Subsequently, several analysis steps are performed on the 18 best detections, which allow us to classify these objects as transiting planet and eclipsing binary candidates. We report one planet candidate orbiting a late G-type star, which is proposed for photometric follow-up. The independent analysis on the M-dwarf sample provides no planet candidates around these stars. Therefore, the null detection hypothesis and upper limits on the occurrence rate of giant planets around M-dwarfs with J < 17 mag presented in a prior study are confirmed. In this work, we extended the search for transiting planets to stars with J < 18 mag, which enables us to impose a more strict upper limit of 1.1 % on the occurrence rate of short-period giant planets around M-dwarfs, which is sign

    2013-01-01

    We proposed a generative probabilistic modeling framework for automated segmentation of retinal layers from Optical Coherence Tomography (OCT) data. The objective is to learn a segmentation protocol from a collection of training images that have been manually labeled. Our model results in a novel OCT retinal layer segmentation approach which integrates algorithms of simultaneous searching of multiple interacting layer interfaces, image registration and machine learning. Different from previous work, our approach combines the benefits of constraining spatial layout of retinal layers, using a set of more robust local image descriptors, employing a mechanism for learning from manual labels and incorporating the inter-subject anatomical similarities of retina. With a set of OCT volumetric images from mutant canine retinas, we experimentally validated that our approach outperforms two state-of-the-art techniques. PMID:24505695

  10. Discovery of Hapten-Specific scFv from a Phage Display Library and Applications for HER2-Positive Tumor Imaging

    PubMed Central

    2015-01-01

    In this study, an anti-hapten antibody (single chain Fv, scFv) against a hapten probe was developed as a unique reporter system for molecular imaging or therapy. The hapten peptide (histamine-succinyl-GSYK, Him) was synthesized for phage displayed scFv affinity selection and for conjugation with cypate (Cy-Him) for in vivo near-infrared (NIR) optical imaging. Hapten-specific scFvs were affinity selected from the human single fold phage display scFv libraries (Tomlinson I + J) with high specificity and affinity. Utilizing HER2 targeting as a model system, the highest affinity scFv (clone J42) was recombinantly fused to an anti-HER2 affibody (scFv-L-Aff) with no loss of affinity of either protein. The functionality of the hapten-scFv reporter system was tested in vitro with a HER2-positive human breast cancer cell line, SK-BR3, and in vivo with SK-BR3 xenografts. ScFv-L-Aff mediated the binding of the hapten to HER2 on SK-BR3 cells and from tissue from the SK-BR3 xenograft; however, scFv-L-Aff did not mediate uptake of the hapten in the SK-BR3 xenografted tumors, presumably due to rapid internalization of the HER2/scFv-L-Aff complex. Our results suggest that this hapten-peptide and anti-hapten scFv can be a universal reporter system in a wide range of imaging and therapeutic applications. PMID:24898150

    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.

    NASA Astrophysics Data System (ADS)

    Pohlmeyer, Eric A.; Wang, Jun; Jangraw, David C.; Lou, Bin; Chang, Shih-Fu; Sajda, Paul

    2011-06-01

    We describe a closed-loop brain-computer interface that re-ranks an image database by iterating between user generated 'interest' scores and computer vision generated visual similarity measures. The interest scores are based on decoding the electroencephalographic (EEG) correlates of target detection, attentional shifts and self-monitoring processes, which result from the user paying attention to target images interspersed in rapid serial visual presentation (RSVP) sequences. The highest scored images are passed to a semi-supervised computer vision system that reorganizes the image database accordingly, using a graph-based representation that captures visual similarity between images. The system can either query the user for more information, by adaptively resampling the database to create additional RSVP sequences, or it can converge to a 'done' state. The done state includes a final ranking of the image database and also a 'guess' of the user's chosen category of interest. We find that the closed-loop system's re-rankings can substantially expedite database searches for target image categories chosen by the subjects. Furthermore, better reorganizations are achieved than by relying on EEG interest rankings alone, or if the system were simply run in an open loop format without adaptive resampling.

  8. Jimmy Carter Library and Museum

    NSDL National Science Digital Library

    Administered by the National Archives and Records Administration (NARA), the Jimmy Carter Library and Museum was opened in 1986. For the benefit of researchers and others who cannot make it to Atlanta, this website provides access to some of the speeches and letters of President Carter, along with biographical information about members of the Carter family. First-time visitors will want to start at the "Documents and Photographs" section. Here, they can look over a special exhibit on the Camp David Accords, read oral history transcripts from members of Carter's cabinet, and peruse Carter's official diary from his time in office. Scholars and those wishing to visit and make use of the library's collections should look over the library information section, which contains details on how to begin searching the collection, and a link for visitors to ask questions online. Rounding out the site is a virtual tour of the museum and library. [KMG

  10. Library Collaboration Aids Global Research

    In the geosciences, organizational libraries and information centers are local sources for scientists, students, and members of the general public who are searching for current or historic information in their fields. They offer focused collections, rare materials, and knowledgeable librarians, but often issues caused by isolation and limited resources impede their ability to fulfill the researchers' needs. Unlike the local university libraries, these small special information centers are usually housed in the same building as their scientists' offices. To help overcome these problems of limited resources and isolation, while retaining the organizational focus and unique collections that are its strengths, the National Snow & Ice Data Center (NSIDC) Information Center has begun to collaborate with similar libraries and information centers. This project has three major steps: 1. Catalog sharing through internet-based links. 2. Resource sharing. 3. Expansion of collaboration. NSIDC is creating catalog links with a sister library, the Institute of Arctic and Alpine Research (INSTAAR) Information Center. Once the links are established, the two libraries will develop a plan for resource sharing and coordinated purchasing. This small collaborative effort will serve as a template for a network of special libraries within Colorado. Ultimately, they hope to expand the collaborative effort to small libraries with a similar focus around the globe. This poster will outline and graphically illustrate these steps, as well as provide a template for future expansion of the project.

    We present the latest results from our project to search for new planetary nebulae in nearby galaxies using Sloan Digital Sky Survey (SDSS) imaging data. Our method is based on photometric criteria and can be applied to galaxies where PNe appear as point sources. We applied these criteria to the whole area of M31 as scanned by SDSS, detecting 130 new PN candidates and 30 known PNe. All selected PNe candidates are located in the outer regions of M31. For 85 candidates follow-up spectroscopy was obtained with the 2.2m telescope at Calar Alto Observatory. The observations show that our method has a detection efficiency of about 82%. We discuss the 2D velocity field of the outer part of M31 based on our observed PN data. The PNe suggest an exponential disk scale length of 13 kpc along the minor axis. We discovered two PNe along the line of sight to Andromeda NE, a very low surface brightness giant stellar structure in the outer halo of M31. These two PNe are located at projected distances of ~48 kpc and ~41 kpc from the center of M31 and are the most distant PNe in M31 found up to now. Our data support the idea that Andromeda NE is located at the distance of M31. No PNe associated with other M31 satellites observed by the SDSS were found. Applying our method to other SDSS regions we checked data for the Local Group galaxies Sextans, Draco, Leo I, Pegasus, Sextans B and Leo A and recovered a known PN in Leo A. We re-measured its O/H and for the first time determined abundances of N/H, S/H, He/H as well as the electron number density Ne. We argue that the PN progenitor was formed ~1.5 Gyr ago during the strongest episode of star formation in Leo A.

  17. 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.

    Image segmentation is considered as one of the crucial steps in image analysis process and it is the most challenging task. Image segmentation can be modeled as a clustering problem. Therefore, clustering algorithms have been applied successfully in image segmentation problems. Fuzzy c-mean (FCM) algorithm is considered as one of the most popular clustering algorithm. Even that, FCM can generate

    This report describes research and development efforts toward a novel passive millimeter-wave (mm-wave) electromagnetic imaging device for broad-area search. It addresses the technical challenge of detecting anomalies that occupy a small fraction of a pixel. The purpose of the imager is to pinpoint suspicious locations for cuing subsequent higher-resolution imaging. The technical basis for the approach is to exploit thermal and polarization anomalies that distinguish man-made features from natural features.
