  2. Refining spectral library searching.

    PubMed

    Rudnick, Paul A

    2013-11-01

    Spectral library searching has many advantages over sequence database searching, yet it has not been widely adopted. One possible reason for this is that users are unsure exactly how to interpret the similarity scores (e.g., "dot products" are not probability-based scores). Methods to create decoys have been proposed, but, as developers caution, may produce proxies that are not equivalent to reversed sequences. In this issue, Shao et al. (Proteomics 2013, 13, 3273-3283) report advances in spectral library searching where the focus is not on improving the performance of their search engine, SpectraST, but is instead on improving the statistical meaningfulness of its discriminant score and removing the need for decoys. The results in their paper indicate that by "standardizing" the input and library spectra, sensitivity is not lost but is, surprisingly, gained. Their tests also show that false discovery rate (FDR) estimates, derived from their new score, track better with "ground truth" than decoy searching. It is possible that their work strikes a good balance between the theory of library searching and its application. And as such, they hope to have removed a major entrance barrier for some researchers previously unwilling to try library searching. PMID:24123856

  5. Planetary Image Geometry Library

    NASA Technical Reports Server (NTRS)

    Deen, Robert C.; Pariser, Oleg

    2010-01-01

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

    2006-01-01

    Libraries handle ever more digital images. Ancient documents, books, manuscripts are digitized, image processing tools extract and assign keywords to the obtained images, but a manual annotation is almost always essential. Manual image annotation and keyword based image search is a difficult and hardly formalizable problem. In this paper we present a model and a system which addresses this issue.

  2. 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.

  3. Building and searching tandem mass spectral libraries for peptide identification.

    PubMed

    Lam, Henry

    2011-12-01

    Spectral library searching is an emerging approach in peptide identifications from tandem mass spectra, a critical step in proteomic data analysis. Conceptually, the premise of this approach is that the tandem MS fragmentation pattern of a peptide under some fixed conditions is a reproducible fingerprint of that peptide, such that unknown spectra acquired under the same conditions can be identified by spectral matching. In actual practice, a spectral library is first meticulously compiled from a large collection of previously observed and identified tandem MS spectra, usually obtained from shotgun proteomics experiments of complex mixtures. Then, a query spectrum is then identified by spectral matching using recently developed spectral search engines. This review discusses the basic principles of the two pillars of this approach: spectral library construction, and spectral library searching. An overview of the software tools available for these two tasks, as well as a high-level description of the underlying algorithms, will be given. Finally, several new methods that utilize spectral libraries for peptide identification in ways other than straightforward spectral matching will also be described. PMID:21900153

    Devillard, Nicolas

    2011-12-01

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

    Hosono, Kimio; Tanaka, Isao; Fukazawa, Yoshiko

    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.

  4. 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.

  7. Database search services as a basic service in academic health sciences libraries.

    PubMed

    Jankowski, T A; Martin, E R

    1994-10-01

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

    2012-03-01

    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

    NASA Astrophysics Data System (ADS)

    Gwyn, S.; Hill, N.; Kavelaars, J.

    2014-07-01

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

    2015-01-01

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

    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. Experimental evaluations on three different histology image data sets show that our strategy is a simple, yet effective approach to building multimodal representations for histology image search, and outperforms the response of the popular late fusion approach to combine information.

  14. Novel search algorithms for a mid-infrared spectral library of cotton contaminants.

    PubMed

    Loudermilk, J Brian; Himmelsbach, David S; Barton, Franklin E; de Haseth, James A

    2008-06-01

    During harvest, a variety of plant based contaminants are collected along with cotton lint. The USDA previously created a mid-infrared, attenuated total reflection (ATR), Fourier transform infrared (FT-IR) spectral library of cotton contaminants for contaminant identification as the contaminants have negative impacts on yarn quality. This library has shown impressive identification rates for extremely similar cellulose based contaminants in cases where the library was representative of the samples searched. When spectra of contaminant samples from crops grown in different geographic locations, seasons, and conditions and measured with a different spectrometer and accessories were searched, identification rates for standard search algorithms decreased significantly. Six standard algorithms were examined: dot product, correlation, sum of absolute values of differences, sum of the square root of the absolute values of differences, sum of absolute values of differences of derivatives, and sum of squared differences of derivatives. Four categories of contaminants derived from cotton plants were considered: leaf, stem, seed coat, and hull. Experiments revealed that the performance of the standard search algorithms depended upon the category of sample being searched and that different algorithms provided complementary information about sample identity. These results indicated that choosing a single standard algorithm to search the library was not possible. Three voting scheme algorithms based on result frequency, result rank, category frequency, or a combination of these factors for the results returned by the standard algorithms were developed and tested for their capability to overcome the unpredictability of the standard algorithms' performances. The group voting scheme search was based on the number of spectra from each category of samples represented in the library returned in the top ten results of the standard algorithms. This group algorithm was able to identify correctly as many test spectra as the best standard algorithm without relying on human choice to select a standard algorithm to perform the searches.

  15. Hunting for unexpected post-translational modifications by spectral library searching with tier-wise scoring.

    PubMed

    Ma, Chun Wai Manson; Lam, Henry

    2014-05-01

    Discovering novel post-translational modifications (PTMs) to proteins and detecting specific modification sites on proteins is one of the last frontiers of proteomics. At present, hunting for post-translational modifications remains challenging in widely practiced shotgun proteomics workflows due to the typically low abundance of modified peptides and the greatly inflated search space as more potential mass shifts are considered by the search engines. Moreover, most popular search methods require that the user specifies the modification(s) for which to search; therefore, unexpected and novel PTMs will not be detected. Here a new algorithm is proposed to apply spectral library searching to the problem of open modification searches, namely, hunting for PTMs without prior knowledge of what PTMs are in the sample. The proposed tier-wise scoring method intelligently looks for unexpected PTMs by allowing mass-shifted peak matches but only when the number of matches found is deemed statistically significant. This allows the search engine to search for unexpected modifications while maintaining its ability to identify unmodified peptides effectively at the same time. The utility of the method is demonstrated using three different data sets, in which the numbers of spectrum identifications to both unmodified and modified peptides were substantially increased relative to a regular spectral library search as well as to another open modification spectral search method, pMatch.

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

    The increasing importance of the Internet demands that toxicologists become aquainted with its resources. To find information, researchers must be able to effectively use Internet search engines, directories, subject-oriented websites, and library catalogs. The article will explain these resources, explore their benefits and weaknesses, and identify skills that help the researcher to improve search results and critically evaluate sources for their relevancy, validity, accuracy, and timeliness.

    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.

    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.

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

    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.

  18. Rochester Images

    NSDL National Science Digital Library

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

    The objective of our research is to understand the perception of multiple abnormalities in an imaging examination and to develop strategies for improved diagnostic. We are one of the few laboratories in the world pursuing the goal of reducing detection errors through a better understanding of the underlying perceptual processes involved. Failure to detect an abnormality is the most common class of error in diagnostic imaging and generally is considered the most serious by the medical community. Many of these errors have been attributed to "satisfaction of search," which occurs when a lesion is not reported because discovery of another abnormality has "satisfied" the goal of the search. We have gained some understanding of the mechanisms of satisfaction of search (SOS) traditional radiographic modalities. Currently, there are few interventions to remedy SOS error. For example, patient history that the prompts specific abnormalities, protects the radiologist from missing them even when other abnormalities are present. The knowledge gained from this programmatic research will lead to reduction of observer error.

    The Wide Field Imager Lyman-Alpha Search (WFILAS) is a search for Lya emitting galaxies at z~5.7. Deep images from the Wide Field Imager (WFI) on the ESO/MPI 2.2m telescope have been used to detect 7 bright Lya emitting candidates in three fields covering 0.74 sq. degree on the sky. For this we used three narrowband (FWHM ~70A), one encompassing intermediate band (FWHM \\~220A) and broadband B and R filters. One has thus far been spectroscopically confirmed as a Lya emitting galaxy at z=5.721 using FORS2 at the VLT. This galaxy shows a bright, well resolved asymmetric line profile, which is characteristic of Lya emitting galaxies. In one of our three fields, the Chandra Deep Field South (CDFS), we find an overdensity of Lya emitters in agreement with other surveys that have targeted this region. A statistically complete sample of our candidates probes the bright-end of the luminosity function, confirming earlier results from other smaller, deeper surveys.

In addition, this paper also introduces a methodology to evaluate the performance of the algorithms in the prototype system. There are two major contributions: we suggest an approach that incorporates various image processing techniques including Gabor filters, image enhancement and image compression, as well as information analysis techniques such as the self-organizing map (SOM) into an effective large-scale geographical image retrieval system. We present two experiments that evaluate the performance of the Gabor-filter-extracted features along with the corresponding similarity measure against that of human perception, addressing the lack of studies in assessing the consistency between an image representation algorithm or an image categorization method and human mental model.

  16. 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.

    In this paper we present an approach to teaching image processing and pattern recognition with the use of the OpenCV library. 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.

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

  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.

    2011-01-01

    This report presents the high-resolution image acquisition and processing instrument for compound management applications (HIAPI-CM). The HIAPI-CM combines imaging spectroscopy and machine vision analysis to perform rapid assessment of HTS compound library quality. It has been customized to detect and classify typical artifacts found in HTS compound library microtiter plates (MTPs). These artifacts include: (a) insufficient volume of liquid compound sample, (b) compound precipitation, and (c) colored compounds that interfere with HTS assay detection format readout. The HIAPI-CM is also configured to automatically query & compare its analysis results to data stored in a LIMS or corporate database, aiding in the detection of compound registration errors. To demonstrate its capabilities, several compound plates (n =5760 wells total) containing different artifacts were measured via automated HIAPI-CM analysis, and results compared to those obtained by manual (visual) inspection. In all cases, the instrument demonstrated high fidelity (99.8% empty wells; 100.1% filled wells; 94.4% for partially filled wells; 94.0% for wells containing colored compounds), and in the case of precipitate detection, the HIAPI-CM results significantly exceeded the fidelity of visual observations (220.0%). As described, the HIAPI-CM allows for noninvasive, nondestructive MTP assessment with a diagnostic throughput of about one minute per plate, reducing analytical expenses and improving the quality and stewardship of HTS compound libraries.

    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.

    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.

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.

    2005-05-01

    This paper provides an overview of research in search and detection modeling of military imaging systems. For more than forty-five years the US Army Night Vision and Electronic Sensors Directorate (NVESD) and others have been working to model the performance of infrared imagers in an effort to link imaging system design parameters to observer-sensor performance in the field. The widely used ACQUIRE model accomplished this by linking the minimum resolvable contrast of the sensor to field performance. From the original hypothesis put forth by John Johnson in 1958, to modeling time limited search, to modeling the impact of motion on target detection, to modeling target acquisition performance in different spectral bands, search has a wide and varied history. This paper will first describe the search-modeling task and then give a description of various topics in search and detection over the years. Some of the topics to be discussed will be classic search, clutter, computational vision models and the ACQUIRE model with its variants. It is hoped that this overview will provide both the novice and experienced search modeler alike with a useful summary and a glance at current issues and future challenges.

  13. 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. SGI, IRIS 4D and IRIX are trademarks of Silicon Graphics, Inc. PostScript is a registered trademark of Adobe Systems Incorporated. UNIX is a registered trademark of AT&T.

  14. Matched filtering determines human visual search in natural images

    NASA Astrophysics Data System (ADS)

    Toet, Alexander

    2011-05-01

    The structural image similarity index (SSIM), introduced by Wang and Bovik (IEEE Signal Processing Letters 9-3, pp. 81-84, 2002) measures the similarity between images in terms of luminance, contrast en structure. It has successfully been deployed to model human visual perception of image distortions and modifications in a wide range of different imaging applications. Chang and Zhang (Infrared Physics & Technology 51-2, pp. 83-90, 2007) recently introduced the target structural similarity (TSSIM) clutter metric, which deploys the SSIM to quantify the similarity of a target to its background in terms of luminance, contrast en structure. They showed that the TSSIM correlates significantly with mean search time and detection probability. However, it is not immediately obvious to what extent each of the three TSSIM components contributes to this correlation. Here we evaluate the TSSIM by deploying it to a set of natural images for which human visual search data are available: the Search_2 dataset. By analyzing the predictive performance of each of the three TSSIM components, we find that it is predominantly the structural similarity component which determines human visual search performance, whereas the luminance and contrast components of the TSSIM show no relation with human performance. Since the structural similarity component of the TSSIM is equivalent to a matched filter, it appears that matched filtering predicts human visual performance when searching for a known target.

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

  16. An attribute-assisted reranking model for web image search.

    PubMed

    Cai, Junjie; Zha, Zheng-Jun; Wang, Meng; Zhang, Shiliang; Tian, Qi

    2015-01-01

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

    2015-01-01

    Telecytology is a new research area that holds the potential of significantly reducing the number of deaths due to cervical cancer in developing countries. This work presents a novel super-resolution technique that couples high and low frequency information in order to reduce the bandwidth consumption of cervical image transmission. The proposed approach starts by decomposing into wavelets the high resolution images and transmitting only the lower frequency coefficients. The transmitted coefficients are used to reconstruct an image of the original size. Additional details are added by iteratively replacing patches of the wavelet reconstructed image with equivalent high resolution patches from a previously acquired image database. Finally, the original transmitted low frequency coefficients are used to correct the final image. Results show a higher signal to noise ratio in the proposed method over simply discarding high frequency wavelet coefficients or replacing directly down-sampled patches from the image-database.

  2. Search and detection modeling of military imaging systems

    NASA Astrophysics Data System (ADS)

    Maurer, Tana; Wilson, David L.; Driggers, Ronald G.

    2013-04-01

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

    Piantanida, Giovanna; Bicchieri, Marina; Pinzari, Flavia; Coluzza, Carlo

    2005-06-01

    Atomic Force Microscopy (AFM) has been used to study fiber degradations, as they appear on paper surface, aiming -in the mid term- at assessment of a micro-destructive technique capable of providing qualitative and semi-quantitative information on deterioration and ageing. AFM topographies of pure cellulose paper samples artificially aged were considered as well as topographies of original paper samples naturally aged showing different kind of deterioration. Whatman N.1 chromatography paper was used as a model system to study ageing effect on sub-micron structures on cellulose fibers. Chemical and biological deterioration processes were modeled, as well, by mean of artificial degradation treatments, following the criteria of reproducing effects frequently isolated from library materials. The effects of chemical reaction induced by accelerated ageing in climatic chamber (80°C, R.H. 65%) on paper surface, and the effects of a fungal attack reproduced in vitro inoculating paper samples with Aspergillus terreus Thom (6000spores/100?l, 27°C, R.H. 100%) were evaluated by means of Atomic Force Microscopy imaging, and spectrophotometric measurement in the UV-Vis-NIR. In order to map structure local properties, morphological variations repeated with statistical relevance were correlated to chemical, biological and spectroscopic characterization. Information achieved from such analysis is then used for a comparison with measurements of naturally aged paper, providing insight in analysis and classification of typical phenomena, like yellowing and foxing stains, usually affecting valuables in libraries.

    2009-09-01

    Radiology has a recognised role in undergraduate anatomy education. The recent digitalisation of radiology has created new learning opportunities involving techniques such as image labelling, 3D reconstruction, and multiplanar reformatting. An opportunity was identified at the University of Nottingham to create a digital library of normal radiology images as a learner-driven adjunct in anatomy dissection sessions. We describe the process of creating a de novo digital library by sourcing images for presentation at computer workstations. Students' attitudes towards this new resource were assessed using a questionnaire which used a 5 point Likert scale and also offered free text responses. One hundred and forty-one out of 260 students (54%) completed the questionnaire. The most notable findings were: a positive response to the relevance of imaging to the session topics (median score 4), strong agreement that images should be available on the university website (median score 5), and disagreement that enough workstations were available (median score 2). About 24% of respondents suggested independently that images needed more labeling to help with orientation and identification. This first phase of supplying a comprehensive imaging library can be regarded as a success. Increasing availability and incorporating dynamic labeling are well recognized as important design concepts for electronic learning resources and these will be improved in the second phase of delivery as a direct result of student feedback. Hopefully other centers can benefit from this experience and will consider such a venture to be worthwhile. PMID:19637297

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

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

  15. Synthesis and Systematic Evaluation of Dark Resonance Energy Transfer (DRET)-Based Library and Its Application in Cell Imaging.

    Su, Dongdong; Teoh, Chai Lean; Kang, Nam-Young; Yu, Xiaotong; Sahu, Srikanta; Chang, Young-Tae

    2015-03-01

    In this paper, we report a new strategy for constructing a dye library with large Stokes shifts. By coupling a dark donor with BODIPY acceptors of tunable high quantum yield, a novel dark resonance energy transfer (DRET)-based library, named BNM, has been synthesized. Upon excitation of the dark donor (BDN) at 490?nm, the absorbed energy is transferred to the acceptor (BDM) with high efficiency, which was tunable in a broad range from 557?nm to 716?nm, with a high quantum yield of up to 0.8. It is noteworthy to mention that the majority of the non-radiative energy loss of the donor was converted into the acceptor's fluorescence output with a minimum leak of donor emission. Fluorescence imaging tested in live cells showed that the BNM compounds are cell-permeable and can also be employed for live-cell imaging. This is a new library which can be excited through a dark donor allowing for strong fluorescence emission in a wide range of wavelengths. Thus, the BNM library is well suited for high-throughput screening or multiplex experiments in biological applications by using a single laser excitation source. PMID:25530300

  16. 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).

  4. Direct imaging searches for planets around white dwarf stars

    NASA Astrophysics Data System (ADS)

    Burleigh, Matt; Hogan, Emma; Clarke, Fraser

    White dwarfs are excellent targets for direct imaging searches for extra-solar planets, since they are up to 10^4 times fainter than their main sequence progenitors, providing a huge gain in the contrast problem. In addition, the orbits of planetary companions that lie beyond the maximum extent of the Red Giant envelope are expected to widen considerably, improving resolution and further encouraging direct detection. We discuss current searches for planetary companions to white dwarfs, including our own “DODO” programme. At the time of writing, no planetary companion to a white dwarf has been detected. The most sensitive searches have been capable of detecting companions ?5M_{Jup}, and their non-detection is consistent with the conclusions of McCarthy & Zuckerman (2004), that no more than 3% of stars harbour 5-10M_{Jup} planets at orbits between 75-300AU. Extremely Large Telescopes are required to enable deeper searches sensitive to lower mass planets, and to provide larger target samples including more distant and older white dwarfs. ELTs will also enable spectroscopic follow-up for any resolved planets, and follow-up of any planetary companions discovered astrometrically by GAIA and SIM.

    As remote sensing technology become ever more powerful with multi-platform and multi-sensor, it has been widely recognized for contributing to geospatial information efforts. Because the remotely sensed image processing demands large-scale, collaborative processing and massive storage capabilities to satisfy the increasing demands of various applications, the effect and efficiency of the remotely sensed image processing is far from the user's expectation. The emergence of Service Oriented Architecture (SOA) may make this challenge manageable. It encapsulate all processing function into services and recombine them with service chain. The service composition on demand has become a hot topic. Aiming at the success rate, quality and efficiency of processing service composition for remote sensing application, a remote sensed image processing service composition method is proposed in this paper. It composes services for a user requirement through two steps: 1) dynamically constructs a complete service dependency graph for user requirement on-line; 2) AO* based heuristic searches for optimal valid path in service dependency graph. These services within the service dependency graph are considered relevant to the specific request, instead of overall registered services. The second step, heuristic search is a promising approach for automated planning. Starting with the initial state, AO* uses a heuristic function to select states until the user requirement is reached. Experimental results show that this method has a good performance even the repository has a large number of processing services.

    2007-07-01

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

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

    PubMed Central

    2014-01-01

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

    2012-06-01

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

  10. Library Synthesis, Screening, and Discovery of Modified Zinc(II)-Bis(dipicolylamine) Probe for Enhanced Molecular Imaging of Cell Death

    PubMed Central

    2015-01-01

    Zinc(II)-bis(dipicolylamine) (Zn-BDPA) coordination complexes selectively target the surfaces of dead and dying mammalian cells, and they have promise as molecular probes for imaging cell death. A necessary step toward eventual clinical imaging applications is the development of next-generation Zn-BDPA complexes with enhanced affinity for the cell death membrane biomarker, phosphatidylserine (PS). This study employed an iterative cycle of library synthesis and screening, using a novel rapid equilibrium dialysis assay, to discover a modified Zn-BDPA structure with high and selective affinity for vesicles containing PS. The lead structure was converted into a deep-red fluorescent probe and its targeting and imaging performance was compared with an unmodified control Zn-BDPA probe. The evaluation process included a series of FRET-based vesicle titration studies, cell microscopy experiments, and rat tumor biodistribution measurements. In all cases, the modified probe exhibited comparatively higher affinity and selectivity for the target membranes of dead and dying cells. The results show that this next-generation deep-red fluorescent Zn-BDPA probe is well suited for preclinical molecular imaging of cell death in cell cultures and animal models. Furthermore, it should be possible to substitute the deep-red fluorophore with alternative reporter groups that enable clinically useful, deep-tissue imaging modalities, such as MRI and nuclear imaging.

    2014-01-01

    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

For the M dwarfs of the solar neighborhood, we have obtained a very accurate mass-luminosity relation that we can compare to the prediction of recent stellar structure models. We also present multiplicity statistics of M dwarfs (binary fraction, period and mass ratio distribution), which are crucial constraints for stellar formation scenarii. We also discuss results obtained on two young closeby associations, MBM12 and Tucana-Horologium.

    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.

  1. PMD2HD – A web tool aligning a PubMed search results page with the local German Cancer Research Centre library collection

    PubMed Central

    Bohne-Lang, Andreas; Lang, Elke; Taube, Anke

    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.

  3. Direct Imaging Searches with the Apodizing Phase Plate Coronagraph

    NASA Astrophysics Data System (ADS)

    Kenworthy, M.; Meshkat, T.; Otten, , G.; Codona, J.

    2014-03-01

    The sensitivity of direct imaging searches for extrasolar planets is limited by the presence of diffraction rings from the primary star. Coronagraphs are angular filters that minimise these diffraction structures whilst allowing light from faint companions to shine through. The Apodizing Phase Plate (APP; Kenworthy 2007) coronagraph is a simple pupil plane optic that suppresses diffraction over a 180 degree region around each star simultaneously, providing easy beam switching observations and requiring no time consuming optical alignment at the telescope. We will present our results on using the APP at the Very Large Telescope in surveys for extrasolar planets around A/F and debris disk hosting stars in the L' band (3.8 microns) in the Southern Hemisphere, where we reach a contrast of 12 magnitudes at 0.5 arcseconds (Meshkat 2013). In Leiden, we are also developing the next generation of broadband achromatic coronagraphs that can simultaneously image both sides of the star using Vector APPs (Snik 2012, Otten 2012). Recent laboratory results showing the potential of this technology for future ELTs will also be presented.

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

    Because of the relative ease in understanding and processing text, commercial image-search systems often rely on techniques that are largely indistinguishable from text-search. Recently, academic studies have demonstrated the effectiveness of employing image-based features to provide alternative or additional signals. However, it remains uncertain whether such techniques will generalize to a large number of popular web queries, and whether the potential improvement to search quality warrants the additional computational cost. In this work, we cast the image-ranking problem into the task of identifying "authority" nodes on an inferred visual similarity graph and propose VisualRank to analyze the visual link structures among images. The images found to be "authorities" are chosen as those that answer the image-queries well. To understand the performance of such an approach in a real system, we conducted a series of large-scale experiments based on the task of retrieving images for 2000 of the most popular products queries. Our experimental results show significant improvement, in terms of user satisfaction and relevancy, in comparison to the most recent Google Image Search results. Maintaining modest computational cost is vital to ensuring that this procedure can be used in practice; we describe the techniques required to make this system practical for large scale deployment in commercial search engines.

    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

    The sesquiterpenoid curdione is one of the main bioactive components in the essential oil of Rhizoma Curcumae (Curcuma wenyujin, Curcuma phaeocaulis, and Curcuma kwangsiensis), which has been clinically used for the treatment of cancer in mainland China. Recently it was reported that natural curdione could be hydroxylated by Aspergillus niger and transferred to its corresponding curcumalactones under acidic conditions. Based on this study, the development of a sesquiterpenoid library through the "mirror-image" manipulation of bioactive (non)natural curdione scaffolds by chemical and biological approaches is presented herein. A. niger induced the hydroxylation of two pairs of curdione enantiomers, yielding the corresponding mirror-image hydroxylated curdiones. Simultaneously, the acid-mediated intramolecular "ene" rearrangements of these curdiones and hydroxylated curdione enantiomers yielded the corresponding mirror-image curcumalactones and hydroxylated curcumalactones. Among the 16 pairs of enantiomers obtained in this study, 23 compounds are new sesquiterpenoids. These curdione and curcumalactone derivatives are of particular interest, as they have the potential to be used as lead compounds and scaffolds in drug discovery. PMID:25679443

    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

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

    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

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

    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.

  1. An adaptive image enhancement technique by combining cuckoo search and particle swarm optimization algorithm.

    PubMed

    Ye, Zhiwei; Wang, Mingwei; Hu, Zhengbing; Liu, Wei

    2015-01-01

    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.

    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.

    NASA Astrophysics Data System (ADS)

    Nakariyakul, Songyot

    2014-11-01

    Two new sequential search algorithms for feature selection in hyperspectral remote sensing images are proposed. Since many wavebands in hyperspectral images are redundant and irrelevant, the use of feature selection to improve classification results is highly needed. First, we present a new generalized steepest ascent (GSA) feature selection technique that improves upon the prior steepest ascent algorithm by selecting a better starting search point and performing a more thorough search. It is guaranteed to provide solutions that equal or exceed those of the classical sequential forward floating selection algorithm. However, when the number of available wavebands is large, the computational load required for the GSA algorithm becomes excessive. We thus propose a modification of the improved floating forward selection algorithm which is more computationally efficient. Experimental results for two hyperspectral data sets show that our proposed algorithms yield better classification results than other suboptimal search algorithms.

    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

    The Kohler Art Library at University of Wisconsin-Madison presents this illustrated database that indexes roughly 760 titles from its collection of over 800 artists' books. The database can be searched by book title, creator's name, publisher, date, or subjects. Other search terms relate to types of book structures, bindings, medium/technique, and contributors. Each record in the database has either a short description of the book's contents or a complete transcription of the colophon, the short paragraph traditionally placed at the end of a book, that tells about its production. In addition, for slightly more than half the books, several images are included. For example, the colophon for From a housewife's diary, by Claire Van Vliet, states that the "covering is dish towels bound by James Bicknell", and the image included shows that the towels are red plaid.

  1. 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.

    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.

    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.

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

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

    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.

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

    This article proposes a multi-objective clustering ensemble method for medical image segmentation. The proposed method is called adaptive multi-objective archive-based hybrid scatter search (AMAHSS). It utilizes fuzzy clustering with optimization of three fitness functions: global fuzzy compactness of the clusters, fuzzy separation and symmetry distance-based cluster validity index. The AMAHSS enables the search strategy to explore intensively the search space

  8. Keynote Talk: Mining the Web 2.0 for Improved Image Search

    NASA Astrophysics Data System (ADS)

    Baeza-Yates, Ricardo

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

    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.

    2013-01-01

    We present a status report on the Subaru SEEDS sub-program to search for extra-solar planets around high-mass (mostly A-type) stars. We describe the early-type star target sample, observing procedures, and early results, including the discovery of a new exoplanet. SEEDS, the Strategic Exploration of Exoplanets and Disks with Subaru, is a multi-year, direct-imaging survey to explore the link between planets and disks, and the evolution of protoplanetary systems and debris disks. It is an international project approved by National Astronomical Observatory of Japan (NAOJ) and led by PI M. Tamura. The SEEDS team is comprised of over 25 institutes with more than 90 members participating. With first observations carried out in 2009, the high-mass star sub-program uses the Subaru 8-meter Telescope, a 188 actuator curvature AO system (AO188), and a near infrared imaging science camera (HiCIAO) to search for exoplanet signatures.

  11. 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.

  14. Metric performance in similar blocks search and their use in collaborative 3D filtering of grayscale images

    NASA Astrophysics Data System (ADS)

    Rubel, Aleksey S.; Lukin, Vladimir V.; Egiazarian, Karen O.

    2014-02-01

    Similar blocks (patches) search plays an important role in image processing. However, there are many factors making this search problematic and leading to errors. Noise in images that arises due to bad acquisition conditions or other sources is one of the main factors. Performance of similar patch search might make worse dramatically if noise level is high and/or if noise is not additive, white and Gaussian. In this paper, we consider the influence of similarity metrics (distances) on search performance. We demonstrate that robustness of similarity metrics is a crucial issue for performance of similarity search. Two models of additive noise are used: AWGN and spatially correlated noise with a wide set of noise standard deviations. To investigate metric performance, five test images are used for artificially inserted group of identical blocks. Metric effectiveness evaluation is carried out for nine different metric (including several unconventional ones) in three domains (one spatial and two spectral). It is shown that conventional Euclidian metric might be not the best choice which depends upon noise properties and data processing domain. After establishing the best metrics, they are exploited within non-local image denoising, namely the BM3D filter. This filter is applied to intensity images of the database TID2008. It is demonstrated that the use of more robust metrics instead of classical ones (Euclidean) in BM3D filter allows improving similar block search and, as a result, provides better results of image denoising for the case of spatially correlated noise.

  15. Cathodoluminescence : an imaging technique for the search of extraterrestrial life

    2012-04-01

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

    Gao, Yue; Wang, Meng; Zha, Zheng-Jun; Shen, Jialie; Li, Xuelong; Wu, Xindong

    2013-01-01

    Due to the popularity of social media websites, extensive research efforts have been dedicated to tag-based social image search. Both visual information and tags have been investigated in the research field. However, most existing methods use tags and visual characteristics either separately or sequentially in order to estimate the relevance of images. In this paper, we propose an approach that simultaneously utilizes both visual and textual information to estimate the relevance of user tagged images. The relevance estimation is determined with a hypergraph learning approach. In this method, a social image hypergraph is constructed, where vertices represent images and hyperedges represent visual or textual terms. Learning is achieved with use of a set of pseudo-positive images, where the weights of hyperedges are updated throughout the learning process. In this way, the impact of different tags and visual words can be automatically modulated. Comparative results of the experiments conducted on a dataset including 370+images are presented, which demonstrate the effectiveness of the proposed approach. PMID:22692911

  6. Advanced spectral imaging for noninvasive microanalysis of cultural heritage materials: review of application to documents in the U.S. Library of Congress.

    PubMed

    France, Fenella G

    2011-06-01

    Hyperspectral imaging was originally developed for remote sensing and astronomical applications, but adaptations of this technology have been of great benefit to the preservation of cultural heritage. Developments in noninvasive analytical techniques have advanced the preservation of cultural heritage materials by enabling the identification and analysis of a range of materials, utilizing their unique spectral response to nondestructively determine chemical composition, and determining states of deterioration and change due to environmental conditions. When used as a tool for noninvasive characterization of cultural heritage, these spectral imaging systems allow the collection of chemical identification information about materials without sampling, which is a critical factor for cultural heritage materials. The United States Library of Congress has been developing the application of hyperspectral imaging to the preservation and analysis of cultural heritage materials as a powerful noncontact technique. It allows noninvasive characterization of materials, by identifying and characterizing colorants, inks, and substrates with narrow-band illumination to protect the object while also monitoring deterioration or changes due to exhibit and other environmental conditions. Contiguous illumination from the ultraviolet, visible, and infrared spectral regions allows the capture of lost, obscured, and deteriorated information. The resulting image cube allows greater capabilities for mapping and coordinating a range of complementary chemical and spectral analyses. The capabilities of this technique are illustrated by a review of results from analysis of the Waldseemüller World Map, the L'Enfant plan for Washington, D.C., and the first draft of the U.S. Declaration of Independence.

    2011-01-01

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

    2011-12-01

    The discovery of 51 Peg in 1995 initiated the search for extrasolar planets with radial velocity. Since then, more than 330 expoplanets have been discovered with this successful technique. After a more timid start, the search for extrasolar planets with the transit method has begun to collect very promising results (55 planets discovered up till now). COROT, Kepler, TESS and ground-based surveys will provide many more candidates in a short term future. Moreover, for a selected sample of transiting exoplanets it is already possible to probe their atmospheres. Although very successful, both these methods are sensitive to planets which orbit quite close to their parent star. High contrast imaging will be the new frontier for exoplanet search and characterization. This technique will provide the opportunity to explore planets with masses down to the earth mass and/or orbiting at larger separation from their parent star, especially in the habitable zone. The possibility to couple an integral field spectrograph to a module for extreme adaptive optics and a 8m class telescope (SPHERE for VLT and GPI for South Gemini) or in the future to ELTs (EPICS), will allow to characterize the atmospheres of the observed exoplanets with low resolution spectroscopy. Here we present the advantages and limits of the high contrast imaging technique to detect and characterize exoplanets in the short and long term future, expecially compared to the RV and Transit methods.

    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

    We present preliminary results of a search for galaxies at z>4 through Lyman-limit imaging of the fields of known high-redshift radio-galaxies. Objects were selected by means of their broad-band colours, and spectroscopy of candidate objects in one of the fields has been performed through multi-slit spectroscopy at the 4.2m William Herschel Telescope. These spectra show some of the first z>4 galaxies to be identified using the Lyman break technique.

  9. 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.

    Coded exposure photography makes the motion de-blurring a well-posed problem. The integration pattern of light is modulated using the method of coded exposure by opening and closing the shutter within the exposure time, changing the traditional shutter frequency spectrum into a wider frequency band in order to preserve more image information in frequency domain. The searching method of optimal code is significant for coded exposure. In this paper, an improved criterion of the optimal code searching is proposed by analyzing relationship between code length and the number of ones in the code, considering the noise effect on code selection with the affine noise model. Then the optimal code is obtained utilizing the method of genetic searching algorithm based on the proposed selection criterion. Experimental results show that the time consuming of searching optimal code decreases with the presented method. The restoration image is obtained with better subjective experience and superior objective evaluation values.

    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.

    2015-01-01

    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.

    2003-10-01

    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.

    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.

    2012-02-01

    The census of faint galaxy satellites around the Milky Way is far from complete. We have systematically searched the RCS2 imaging survey and identified candidates for ultra-faint Milky Way galaxies at larger distances than previously explored. The RCS2 survey covers 750 sq degrees to a limiting magnitude of r~24, two magnitudes below the Sloan Digital Sky Survey in which all the known ultra-faint galaxies have so far been detected. We identify two promising ultra-faint candidates which appear to lie between 400 kpc < d < 800 kpc based on the presence of red giant branch (RGB) stars. We propose Gemini-N GMOS and NIRI imaging in g, r, and J to confirm each candidate by revealing its stellar sequence down the RGB. Two optical and one near- infrared filters are required to distinguish a low-surface brightness stellar population from the sea of unresolved galaxies at faint magnitudes. If confirmed, these will be the first Milky Way ultra-faint galaxies discovered outside of SDSS data, and will be the most distant of these low luminosity systems. If ruled out, these observations will inform our ongoing and future searches of deep, wide-field data for Milky Way satellites.

  3. Genome Clone Libraries and Data from the Integrated Molecular Analysis of Genomes and their Expression (I.M.A.G.E.) Consortium

    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.

    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.

  7. Fully Polarimetric Passive W-band Millimeter Wave Imager for Wide Area Search

    SciTech Connect

    Tedeschi, Jonathan R.; Bernacki, Bruce E.; Sheen, David M.; Kelly, James F.; McMakin, Douglas L.

    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.

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

    High content image-based screening 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.

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

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

  9. Real-time sound speed correction using golden section search to enhance ultrasound imaging quality

    2013-03-01

    In medical ultrasound imaging, high-performance beamforming is important to enhance spatial and contrast resolutions. A modern receive dynamic beamfomer uses a constant sound speed that is typically assumed to 1540 m/s in generating receive focusing delays [1], [2]. However, this assumption leads to degradation of spatial and contrast resolutions particularly when imaging obese patients or breast since the sound speed is significantly lower than the assumed sound speed [3]; the true sound speed in the fatty tissue is around 1450 m/s. In our previous study, it was demonstrated that the modified nonlinear anisotropic diffusion is capable of determining an optimal sound speed and the proposed method is a useful tool to improve ultrasound image quality [4], [5]. In the previous study, however, we utilized at least 21 iterations to find an optimal sound speed, which may not be viable for real-time applications. In this paper, we demonstrates that the number of iterations can be dramatically reduced using the GSS(golden section search) method with a minimal error. To evaluate performances of the proposed method, in vitro experiments were conducted with a tissue mimicking phantom. To emulate a heterogeneous medium, the phantom was immersed in the water. From the experiments, the number of iterations was reduced from 21 to 7 with GSS method and the maximum error of the lateral resolution between direct and GSS was less than 1%. These results indicate that the proposed method can be implemented in real time to improve the image quality in the medical ultrasound imaging.

    2014-12-01

    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.

    Devitt, Nicole; Moyer, Steve; Young, Susan

    2006-05-01

    This research investigated the effects of using medical imaging enhancement techniques to increase the detectability of targets in the urban terrain. Targets in the urban environment present human observers different challenges than targets located in the traditional, open field, search environment. In the traditional environment, targets typically were military vehicles in a natural background. In the urban environment, targets were humans against a man-made background. The U.S. Army Night Vision and Electronic Sensors Directorate (NVESD) and the U. S. Army Research Laboratory (ARL) explored three image processing techniques: contrast enhancement, edge enhancement, and a multiscale edge domain process referred to as "mountain-view". For the mountain-view presentation, high-contrast edges were enhanced. Human perception experiments were conducted with non-enhanced real imagery collected from an Urban Operations training center. These human perception experiments establish a baseline response. Processing the imagery using the previously mentioned techniques then allowed human perception experiments to be conducted. The performance parameters used for comparison were probability of detection, and time required to detect a target. This research provided a methodology of evaluating and quantifying human performance differences in target acquisition based on image processing techniques in the urban environment.

    NSDL National Science Digital Library

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

    The Common Pipeline Library (CPL) is a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit to create automated astronomical data reduction pipelines. Though initially developed as a standardized way to build VLT instrument pipelines, the CPL may be more generally applied to any similar application. The code also provides a variety of general purpose image- and signal-processing functions, making it an excellent framework for the creation of more generic data handling packages. The CPL handles low-level data types (images, tables, matrices, strings, property lists, etc.) and medium-level data access methods (a simple data abstraction layer for FITS files). It also provides table organization and manipulation, keyword/value handling and management, and support for dynamic loading of recipe modules using programs such as EsoRex (ascl:1504.003).

    Ludwig, L

    1993-01-01

    The Medical Library Association's third annual survey of recent health sciences library building projects identified fourteen libraries planning, expanding, or constructing new library facilities. Three of five new library buildings are freestanding structures where the library occupies all or a major portion of the space. The two other new facilities are for separately administered units where the library is a major tenant. Nine projects involve additions to or renovations of existing space. Six projects are in projected, predesign, or design stages or are awaiting funding approval. This paper describes four projects that illustrate technology's growing effect on librarians and libraries. They are designed to accommodate change, a plethora of electronic gear, and easy use of technology. Outwardly, they do not look much different than many other modern buildings. But, inside, the changes have been dramatic although they have evolved slowly as the building structure has been adapted to new conditions. Images PMID:8251970

  11. An HST Imaging Search for Circumstellar Matter in Young Nebulous Clusters

    NASA Astrophysics Data System (ADS)

    Stapelfeldt, K.; Sahai, R.; Werner, M.; Trauger, J.

    HST imaging studies of the M42 and M16 HII regions have revealed circumstellar emission and absorption regions with sizes comparable to those expected for protoplanetary disks. In order to determine the uniqueness of these results, and to search for additional objects geometrically suggestive of disks, we observed four other young nebulous clusters with HST/WFPC2 during Cycle 5. Eight fields were observed in H? and I-band continuum in the nearby HII regions NGC2024, NGC2264, and S155. Two fields were observed in V band in the reflection nebula NGC7023. In all these fields, no dark silhouettes and only a handful of circumstellar ionized rims were found. These results suggest that the visibility of "proplyds" in the Orion Nebula is due to circumstances unique to the evolutionary state of the Trapezium cluster.

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

    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.

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

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

    NASA Astrophysics Data System (ADS)

    Bowler, Brendan Peter

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

  19. Afghanistan Digital Library

    NSDL National Science Digital Library

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

  9. All-Sky Imaging Search for Transients with the Long Wavelength Demonstrator Array

    The Long Wavelength Demonstrator Array (LWDA) is a prototype 16 element low frequency, phased dipole array. It operates between 60-80 MHz with an instantaneous bandwidth of 1.6 MHz. The system allows cross correlation of each of the 120 pairs of antennas. Dual orthogonal linear polarizations are received and the electronics are capable of digital delay beamforming with two fully-independent beams, as well as all-sky imaging. The LWDA hardware installation was completed in late October 2006, and the instrument successfully achieved first light. The operational system is currently engaged in scientific observations including all-sky surveying for bright continuum transient radio emission, as well as targeted observations of pulsars. The LWDA has observed several solar bursts and should also be sensitive to giant pulses from the Crab pulsar. We describe the current status of the transient detection pipeline and present results from the first year of all-sky monitoring. Initial data were taken in 50 ms snapshots at 74 MHz every 5 minutes. Bright sources such as Cygnus A, Cassiopeia A, the Galactic Plane, and the Sun are clearly visible, but cannot be accurately modeled given the irregular time sampling and sensitivity variations across the primary beam. These sources were masked for the transient search. Additionally, an instrumental issue led to flagging high amplitude data with phase near zero; thus we are not sensitive to transients directly overhead or near the masked sources. We reach a sensitivity of 400 Jy/bm over the remaining sky. More regular sampling has been implemented and will allow us to build up a standard "Sky model" which varies with time over the day. By comparing new data to this standard we will be able to search for transients over the whole sky. Basic research in radio astronomy at the Naval Research Laboratory is supported by 6.1 base funding.

  12. 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

  13. Special Collections and Archives Image Database

    NSDL National Science Digital Library

    The Cline Library Special Collections and Archives Department (SCA) houses over 700,000 photographic images, tens of thousands of which are now available online. The library has digitized dozens of collections, including the Philip Johnston Collection with 265 images documenting life on the Navajo Reservation between 1895 and 1945; the Fronske studio collection, approximately 395 black-and-white photographs documenting over four decades of southwestern people, events, and history; and the Northern Arizona University's Photographic Archives and General Photos collection. The site offers several options for searching and browsing. For users interested only in the online collection, the Finding Guide will be extremely useful in identifying and accessing digitized materials. It is unfortunate that the images seem to be available only in smaller size, but the site provides substantial catalog information for each image and healthy descriptions of the content of and circumstances behind each collection.

Interestingly, returns are presented "as is" from the source pages (with page header, images, and unique formats) but combined into a single results page. A test search for "Northern Ireland" on four selected sites returned over 40 results. Direct links to the featured databases and, in some cases, their search tips pages are also provided.

  15. Land Treatment Digital Library

    USGS Publications Warehouse

    Pilliod, David S.

    2009-01-01

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