Public Health Image Library  

NSDL National Science Digital Library

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

A multilingual image search engine.  

PubMed

A multilingual search interface has been created for a large, richly-indexed multi-journal library of medical images. Images are indexed by keywords and medical concepts. Nine non-English languages are supported, including Chinese and Japanese. Queries are translated into Medical Subject Headings (MeSHA(R)) terms through a specialized interface with the U.S. National Library of Medicine. The ARRS GoldMiner(TM) Global search engine presents the query and navigation information in the original language with English-language search results. PMID:18998789

Efficient searching in distributed digital libraries  

Microsoft Academic Search

When a digital library is decomposed into many geographi- cally distributed repositories, search efficiency becomes an is- sue. Increasing network congestion makes this a compelling issue. We discuss an effective method for reducing the num- ber of servers needed to respond to a query and give examples of search space reduction in the NCSTRL distributed digital library.

Medical image libraries: ICoS project  

NASA Astrophysics Data System (ADS)

FOr use of digital techniques for the production, manipulation and storage of images has resulted in the creation of digital image libraries. These libraries often store many thousands of images. While provision of storage media for such large amounts of data has been straightforward, provision of effective searching and retrieval tools has not. Medicine relies heavily on images as a diagnostic tool. The most obvious example is the x-ray, but many other image forms are in everyday use. Advances in technology are affecting the ways medical images are generated, stored and retrieved. The paper describes the work of the Image COding and Segmentation to Support Variable Rate Transmission Channels and Variable Resolution Platforms (ICoS) research project currently under way in Bristol, UK. ICoS is a project of the Mobile of England and Hewlett-Packard Research Laboratories Europe. Funding is provided by the Engineering and PHysical Sciences Research Council. The aim of the ICoS project is to demonstrate the practical application of computer networking to medical image libraries. Work at the University of the West of England concentrates on user interface and indexing issues. Metadata is used to organize the images, coded using the WWW Consortium standard Resource Description Framework. We are investigating the application of such standards to medical images, one outcome being to implement a metadata-based image library. This paper describes the ICoS project in detail and discuses both metadata system and user interfaces in the context of medical applications.

PHDIL: Philadelphia Historical Digital Image Library  

NSDL National Science Digital Library

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

Building and Searching Tandem Mass Spectral Libraries for Peptide Identification*  

PubMed Central

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.

Semantically Enriching the Search System of a Music Digital Library  

NASA Astrophysics Data System (ADS)

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

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

NSDL National Science Digital Library

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

The Impact of On-line Searching on Document Supply Services at Individual Libraries  

NASA Astrophysics Data System (ADS)

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

Ontology driven image search engine  

NASA Astrophysics Data System (ADS)

Image collections are most often domain specific. We have developed a system for image retrieval of multimodal microscopy images. That is, the same object of study visualized with a range of microscope techniques and with a range of different resolutions. In microscopy, image content is depending on the preparation method of the object under study as well as the microscope technique. Both are taken into account in the submission phase as metadata whilst at the same time (domain specific) ontologies are employed as controlled vocabularies to annotate the image. From that point onward, image data are interrelated through the relationships derived from annotated concepts in the ontology. By using concepts and relationships of an ontology, complex queries can be built with true semantic content. Image metadata can be used as powerful criteria to query image data which are directly or indirectly related to original data. The results of image retrieval can be represented using a structural graph by exploiting relationships from ontology rather than a listed table. Applying this to retrieve images from the same subject at different levels of resolution opens a new field for the analysis of image content.

Immediate structured visual search for medical images.  

PubMed

The objective of this work is a scalable, real-time visual search engine for medical images. In contrast to existing systems that retrieve images that are globally similar to a query image, we enable the user to select a query Region Of Interest (ROI) and automatically detect the corresponding regions within all returned images. This allows the returned images to be ranked on the content of the ROI, rather than the entire image. Our contribution is two-fold: (i) immediate retrieval - the data is appropriately pre-processed so that the search engine returns results in real-time for any query image and ROI; (ii) structured output - returning ROIs with a choice of ranking functions. The retrieval performance is assessed on a number of annotated queries for images from the IRMA X-ray dataset and compared to a baseline. PMID:22003711

Interactive searching of facial image databases  

NASA Astrophysics Data System (ADS)

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

To make a visual examination of various chromosome abnormalities, individual chromosome regions have to be determined in an image and classified into distinct chromosome types in advance. We propose a subregion based method to improve this process. The proposed method regards each chromosome region as a series of subregions, and iterates a search for subregions in the subject image consecutively.

Pepitome: evaluating improved spectral library search for identification complementarity and quality assessment  

PubMed Central

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.

Improving e-book access via a library-developed full-text search tool*  

PubMed Central

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

Understanding the foundation: the state of generalist search education in library schools as related to the needs of expert searchers in medical libraries  

PubMed Central

Purpose: The paper explores the current state of generalist search education in library schools and considers that foundation in respect to the Medical Library Association's statement on expert searching. Setting/Subjects: Syllabi from courses with significant searching components were examined from ten of the top library schools, as determined by the U.S. News & World Report rankings. Methodology: Mixed methods were used, but primarily quantitative bibliometric methods were used. Results: The educational focus in these searching components was on understanding the generalist searching resources and typical users and on performing a reflective search through application of search strategies, controlled vocabulary, and logic appropriate to the search tool. There is a growing emphasis on Web-based search tools and a movement away from traditional set-based searching and toward free-text search strategies. While a core set of authors is used in these courses, no core set of readings is used. Discussion/Conclusion: While library schools provide a strong foundation, future medical librarians still need to take courses that introduce them to the resources, settings, and users associated with medical libraries. In addition, as more emphasis is placed on Web-based search tools and free-text searching, instructors of the specialist medical informatics courses will need to focus on teaching traditional search methods appropriate for common tools in the medical domain.

State of the art of expert searching: results of a Medical Library Association survey  

PubMed Central

Objectives: Medical Library Association (MLA) members were surveyed to gather background about the current state of expert searching in institutions. The survey results were intended to guide the recommendations of the Task Force on Expert Searching for promoting the importance of expert searching and implementing those recommendations. Methods: MLA members were surveyed, and data obtained from the survey were compiled and analyzed to answer three general questions: what is the perceived value of searching skills to the institution, how do health sciences librarians maintain and improve their searching skills, and how are searching services promoted and/or mandated in the institution. Results: There were 256 responses to the survey. Over 95% of the respondents saw their expert-searching skills were of value to their institutions, primarily through performing mediated searches and search consultations. Over 83% of the respondents believed that their searching skills had improved over the past 10 years. Most indicated that continued training was very important in maintaining and improving their skills. Respondents promoted searching services most frequently through orientations, brochures, and the libraries' Web pages. No respondent's institution mandated expert searching. Less than 2% of respondents' institutions had best practice guidelines related to expert searching, and only about 8% had guidelines or policies that identified situations where expert searching was recommended. Conclusions: The survey supports the belief that health sciences librarians still play a valuable role in searching, particularly in answering questions about treatment options and in providing education. It also highlights the need for more expert searching courses. There has been minimal discussion about the perceived need for expert-searching guidelines in the institutions represented by survey respondents.

Integrated paleontological data base and image library  

SciTech Connect

MICROBASE (MICROpaleontology data BASE) is an integrated data base and image retrieval system designed to increase the efficiency and precision with which paleontologists access and interpret paleontological and biostratigraphic data. The project is funded by a consortium of oil companies and coordinated by the American Museum of Natural History with assistance from the American Association of Stratigraphic Palynologists. MICROBASE is a PC-based MS DOS-compatible system operating under Microsoft Windows 3.0 that takes advantage of the latest developments in both analog (video) and digital technology. Images are captured using a video camera mounted on a microscope or using a high-resolution scanner for photographic source material. The image is saved either as a digital file or as an analog 'frame' on a Panasonic optical disk recorder (OMDR). The OMDR can store 108,000 images on one 12-in disk with a retrieval and display time of less than 0.15 second. Microfossil data (nomenclature, synonomy, descriptions, stratigraphic distribution, etc.) are stored as relational tables in an ORACLE DBMS (PALeontological CATalog, or PALCAT), and these textural data are linked to multiple images for each taxon. MICROBASE is the first integrated and widely supported system to electronically archive paleontological data, regardless of fossil group. It provides rapid, easy access to paleontological data, resulting in standardized taxonomy, more efficient identification procedures, substantially reduced learning curves for persons unfamiliar with particular groups, and more effective retention of the cumulative expertise of experienced paleontologists. The Ellis and Messina Catalog of Foraminifera is the first paleontological catalog available on the MICROBASE system.

Satisfaction of search experiments in advanced imaging  

NASA Astrophysics Data System (ADS)

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.

Building a Digital Library for Multibeam Data, Images and Documents  

NASA Astrophysics Data System (ADS)

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

In this paper, a problem of isothermic DNA sequencing by hybridization (SBH) is considered. In isothermic SBH a new type of oligonucleotide libraries is used. The library consists of oligonucleotides of different lengths depending on an oligonucleotide content. It is assumed that every oligonucleotide in such a library has an equal melting temperature. Each nucleotide adds its increment to the oligonucleotide temperature and it is assumed that A and T add 2 degrees C and C and G add 4 degrees C. The hybridization experiment using isothermic libraries should provide data with a lower number of errors due to an expected similarity of melting temperatures. From the computational point of view the problem of isothermic DNA sequencing with errors is hard, similarly like its classical counterpart. Hence, there is a need for developing heuristic algorithms that construct good suboptimal solutions. The aim of the paper is to propose a heuristic algorithm based on tabu search approach. The algorithm solves the problem with both positive and negative errors. Results of an extensive computational experiment are presented, which prove the high quality of the proposed method.

NASA Astrophysics Data System (ADS)

We describe a visual information system prototype for searching for images and videos on the World-Wide Web. New visual information in the form of images, graphics, animations and videos is being published on the Web at an incredible rate. However, cataloging this visual data is beyond the capabilities of current text-based Web search engines. In this paper, we describe a complete system by which visual information on the Web is (1) collected by automated agents, (2) processed in both text and visual feature domains, (3) catalogued and (4) indexed for fast search and retrieval. We introduce an image and video search engine which utilizes both text-based navigation and content-based technology for searching visually through the catalogued images and videos. Finally, we provide an initial evaluation based upon the cataloging of over one half million images and videos collected from the Web.

Log analysis to understand medical professionals' image searching behaviour.  

PubMed

This paper reports on the analysis of the query logs of a visual medical information retrieval system that provides access to radiology resources. Our analysis shows that, despite sharing similarities with general Web search and also with biomedical text search, query formulation and query modification when searching for visual biomedical information have unique characteristics that need to be taken into account in order to enhance the effectiveness of the search support offered by such systems. Typical information needs of medical professionals searching radiology resources are also identified with the goal to create realistic search tasks for a medical image retrieval evaluation benchmark.

Detecting atypical examples of known domain types by sequence similarity searching: the SBASE domain library approach.  

PubMed

SBASE is a project initiated to detect known domain types and predicting domain architectures using sequence similarity searching (Simon et al., Protein Seq Data Anal, 5: 39-42, 1992, Pongor et al, Nucl. Acids. Res. 21:3111-3115, 1992). The current approach uses a curated collection of domain sequences - the SBASE domain library - and standard similarity search algorithms, followed by postprocessing which is based on a simple statistics of the domain similarity network (http://hydra.icgeb.trieste.it/sbase/). It is especially useful in detecting rare, atypical examples of known domain types which are sometimes missed even by more sophisticated methodologies. This approach does not require multiple alignment or machine learning techniques, and can be a useful complement to other domain detection methodologies. This article gives an overview of the project history as well as of the concepts and principles developed within this the project. PMID:20887262

Joint Optimization Toward Effective and Efficient Image Search.  

PubMed

The bag-of-words (BoW) model has been known as an effective method for large-scale image search and indexing. Recent work shows that the performance of the model can be further improved by using the embedding method. While different variants of the BoW model and embedding method have been developed, less effort has been made to discover their underlying working mechanism. In this paper, we systematically investigate the image search performance variation with respect to a few factors of the BoW model, and study how to employ the embedding method to further improve the image search performance. Subsequently, we summarize several observations based on the experiments on descriptor matching. To validate these observations in a real image search, we propose an effective and efficient image search scheme, in which the BoW model and embedding method are jointly optimized in terms of effectiveness and efficiency by following these observations. Our comprehensive experiments demonstrate that it is beneficial to employ these observations to develop an image search algorithm, and the proposed image search scheme outperforms state-of-the-art methods in both effectiveness and efficiency.

A supersecondary structure library and search algorithm for modeling loops in protein structures  

PubMed Central

We present a fragment-search based method for predicting loop conformations in protein models. A hierarchical and multidimensional database has been set up that currently classifies 105?950 loop fragments and loop flanking secondary structures. Besides the length of the loops and types of bracing secondary structures the database is organized along four internal coordinates, a distance and three types of angles characterizing the geometry of stem regions. Candidate fragments are selected from this library by matching the length, the types of bracing secondary structures of the query and satisfying the geometrical restraints of the stems and subsequently inserted in the query protein framework where their fit is assessed by the root mean square deviation (r.m.s.d.) of stem regions and by the number of rigid body clashes with the environment. In the final step remaining candidate loops are ranked by a Z-score that combines information on sequence similarity and fit of predicted and observed ?/? main chain dihedral angle propensities. Confidence Z-score cut-offs were determined for each loop length that identify those predicted fragments that outperform a competitive ab initio method. A web server implements the method, regularly updates the fragment library and performs prediction. Predicted segments are returned, or optionally, these can be completed with side chain reconstruction and subsequently annealed in the environment of the query protein by conjugate gradient minimization. The prediction method was tested on artificially prepared search datasets where all trivial sequence similarities on the SCOP superfamily level were removed. Under these conditions it is possible to predict loops of length 4, 8 and 12 with coverage of 98, 78 and 28% with at least of 0.22, 1.38 and 2.47 ? of r.m.s.d. accuracy, respectively. In a head-to-head comparison on loops extracted from freshly deposited new protein folds the current method outperformed in a ?5:1 ratio an earlier developed database search method.

Effective metadata discovery for dynamic filtering of queries to a radiology image search engine.  

PubMed

We sought to demonstrate the effectiveness of techniques to index radiology images using metadata discovered in their free-text figure captions. The ARRS GoldMiner image library incorporated 94,256 figures from 11,712 articles published in peer-reviewed online radiology journals. Algorithms were developed to discover metadata--age, sex, and imaging modality--from the figures' free-text captions. Age was recorded in years, and was classified as infant (less than 2 years), child (2 to 17 years), or adult (18+ years). Each figure was assigned to one of eight imaging modalities. A random sample of 1,000 images was examined to measure accuracy of the metadata. The patient's age was identified in 58,994 cases (63%), and the patient's sex was identified in 58,427 cases (62%). An imaging modality was assigned to 80,402 (85%) of the figures. Based on the 1,000 sampled cases, recall values for age, sex, and imaging modality were 97.2%, 99.7%, and 86.4%, respectively. Precision values for age, sex, and imaging modality were 100%, 100%, and 97.2%, respectively. Automated techniques can accurately discover age, sex, and imaging modality metadata from captions of figures published in radiology journals. The metadata can be used to dynamically filter queries for an image search engine. PMID:17558534

Feasibility of LC/TOFMS and elemental database searching as a spectral library for pesticides in food.  

PubMed

Traditionally, the screening of unknown pesticides in food has been accomplished by GC/MS methods using conventional library-searching routines. However, many of the new polar and thermally labile pesticides are more readily and easily analysed by LC/MS methods and no searchable libraries currently exist (with the exception of some user libraries, which are limited). Therefore, there is a need for LC/MS libraries that can detect pesticides and their degradation products. This paper reports an identification scheme using a combination of LC/MS time-of-flight (accurate mass) and an Access database of 350 pesticides that are amenable to positive ion electrospray. The approach differs from conventional library searching of fragment ions. The concept consists of three parts: (1) initial screening of possible pesticides in actual market-place fruit extracts (apple and orange) using accurate mass and generating an accurate mass via an automatic ion-extraction routine, (2) searching the Access database manually for screening identification of a pesticide, and (3) identification of the suspected compound by accurate mass of at least one fragment ion and comparison of retention time with an actual standard. Imazalil and iprodione were identified in apples and thiabendazole in oranges using this database approach. PMID:17071519

Search and detection modeling of military imaging systems  

NASA Astrophysics Data System (ADS)

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.

Subpixel object detection using hyperspectral imaging for search and rescue operations  

NASA Astrophysics Data System (ADS)

Time critical search & rescue (s&r) operations often requires the detection of small objects in a vast area. While an airborne search can cover the area, no operational instrumental tools currently exist to actually replace the human operator. By producing the spectral signature of each pixel in a spatial image, multi- and hyper-spectral imaging (HSI) sensors provides a powerful capability for automated detection of subpixel size objects that are otherwise unresolved objects in conventional imagery. This property of HSI naturally lends itself to s&r operations. A lost hiker, skier, life raft adrift in the ocean, downed pilot or small aircraft wreckage targets, can be detected from relatively high altitude based on their unique spectral signatures. Moreover, the spectral information obtained allows the search craft to operate at substantially reduced spatial resolution thereby increasing scene coverage without a significant loss in detection sensitivity. The paper demonstrates the detection of objects as small as 1/10 of an image pixel from a sensor flying at over 6 km altitude. A subpixel object detection algorithm using HSI, based on local image statistics without reliance on spectral libraries is presented. The technique is amenable to fast signal processing and the requisite hardware can be built using inexpensive off the shelf technology. This makes HSI a highly attractive tool for real-time, autonomous instrument-based implementation. It can complement current visual-based s&r operations or emerging synthetic aperture radar sensors that are much more expensive.

An interactive histology image-barcode manual for a videodisc image library.  

PubMed

Cell Biology and Histology (alias Microanatomy, alias Microscopic Anatomy) is a required course for first-year medical and dental students in most health science centers. The traditional approach used in teaching this discipline is to present photomicrographic images of structures to students in lecture using 35 mm slides of fields seen through the microscope. The students then spend many hours viewing and studying specimens of tissues using a light microscope in a laboratory setting. Students in traditional courses of histology spend an inordinate amount of time learning the component structures by attempting to find and identify them in tissue sections using a microscope, where the structure being sought is surrounded by a multitude of other structures with which they are also not familiar. With the recent availability of videodisc stored image libraries of histological samples, it is now possible to study histological principles without the use of the microscope as the primary learning tool. A videodisc entitled "Histology: A Photographic Atlas" by S. Downing (published by Image Premastering Services Limited, Minneapolis, MN, 1991) has been incorporated into our histology course. Fifteen videodisc player stations are provided for 150 students. Images are retrieved by students using a bar code scanner attached to a videodisc player (Pioneer CLD-2400). Using this kind of image library, students can now learn basic histological structure, such as cell and tissue types, without the use of a microscope or as a tool for facilitating microscopy. The use of a videodisc library of randomly accessible images simplifies learning the basic components which all organs are composed of by presenting the learner with clear-cut examples to avoid confusion with other structures. However, videodisc players and TV monitors are still not appropriately priced for every student to own. This presents a problem in that the same images studied in class are not available to study and review outside of class. There is a need for resources for additional study outside of the institutional setting, for students to have and interact with to reinforce the learning experience in the teaching laboratory. A hard copy manual was created and is being used in our course; it incorporates photos captured from the videodisc. The images displayed in the manual are chosen to give the student one example of each histological component. Additional labeling is added to the images, and each image is accompanied by a bar code that may be used at a videodisc player with a bar code reader to retrieve the same color image from the disc displayed in larger format on a TV monitor. Each topic in the manual is accompanied by learning objectives and a statement of clinical relevance. Following the presentation of the images in each section of the manual, the students are encouraged to practice by viewing multiple examples of each structural component presented in the lesson. They can do this by using the bar-coded catalog supplied with each disc. The presentation of each topic concludes with a quiz composed of questions about images that the student can retrieve from the videodisc using barcodes in the text of the manual. Some of the images on the quiz are printed in miniature in the manual to provide the student with an opportunity for personal review at home when hardware to obtain and display images from a video disc is not available. This manual provides an answer to the dilemma faced by the learner when access to hardware is not available; reinforcement is therefore facilitated outside the teaching laboratory. This allows learning to continue outside of the classroom, using the same materials. (abstract truncated) PMID:8591555

Multimodal image registration by iteratively searching keypoint correspondences  

NASA Astrophysics Data System (ADS)

This paper proposes a multimodal image registration algorithm through searching the best matched keypoints by employing the global information. Keypoints are detected from images from both the reference and test images. For each test keypoint, a certain number of reference keypoints are chosen as mapping candidates. A triplet of keypoint mappings determine an affine transformation, and then it is evaluated with the similarity metric between the reference image and the transformed test image by the determined transformation. An iterative process is conducted on triplets of keypoint mappings, and for every test keypoint updates and stores its best matched reference keypoint. The similarity metric is defined to be the number of overlapped edge pixels over entire images, allowing for global information being incorporated in evaluating triplets of mappings. Experimental results show that the proposed algorithm can provide more accurate registration than existing methods on EO-IR images.

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

SciTech Connect

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

Do images involuntarily trigger search? A test of Pillsbury's hypothesis.  

PubMed

Pillsbury (1908) suggested that deciding to search for something in a scene consists of nothing more than forming a visual image of the target. If so, imaging should trigger search even when it would be more advantageous not to search. Subjects were cued to form an image of a specified object (e.g., tiger) and to press a key when they had done so. This initiated the presentation of a sequence of pictures, with a single target digit interspersed; the subject's task was to report this digit. The sequence contained a picture of the same type of object that the subject had just imaged (e.g., a tiger), either before or after the target digit. If this picture was detected involuntarily, an attentional blink should have impaired digit detection when the picture preceded the digit. This was confirmed in two experiments, even when instructions specifically encouraged subjects to discard the image and to avoid searching for it. The results support Pillsbury's hypothesis.

World Wide Web Based Image Search Engine Using Text and Image Content Features  

NASA Astrophysics Data System (ADS)

Using both text and image content features, a hybrid image retrieval system for Word Wide Web is developed in this paper. We first use a text-based image meta-search engine to retrieve images from the Web based on the text information on the image host pages to provide an initial image set. Because of the high-speed and low cost nature of the text-based approach, we can easily retrieve a broad coverage of images with a high recall rate and a relatively low precision. An image content based ordering is then performed on the initial image set. All the images are clustered into different folders based on the image content features. In addition, the images can be re-ranked by the content features according to the user feedback. Such a design makes it truly practical to use both text and image content for image retrieval over the Internet. Experimental results confirm the efficiency of the system.

Development and experimental test of support vector machines virtual screening method for searching Src inhibitors from large compound libraries  

PubMed Central

Background Src plays various roles in tumour progression, invasion, metastasis, angiogenesis and survival. It is one of the multiple targets of multi-target kinase inhibitors in clinical uses and trials for the treatment of leukemia and other cancers. These successes and appearances of drug resistance in some patients have raised significant interest and efforts in discovering new Src inhibitors. Various in-silico methods have been used in some of these efforts. It is desirable to explore additional in-silico methods, particularly those capable of searching large compound libraries at high yields and reduced false-hit rates. Results We evaluated support vector machines (SVM) as virtual screening tools for searching Src inhibitors from large compound libraries. SVM trained and tested by 1,703 inhibitors and 63,318 putative non-inhibitors correctly identified 93.53%~ 95.01% inhibitors and 99.81%~ 99.90% non-inhibitors in 5-fold cross validation studies. SVM trained by 1,703 inhibitors reported before 2011 and 63,318 putative non-inhibitors correctly identified 70.45% of the 44 inhibitors reported since 2011, and predicted as inhibitors 44,843 (0.33%) of 13.56M PubChem, 1,496 (0.89%) of 168 K MDDR, and 719 (7.73%) of 9,305 MDDR compounds similar to the known inhibitors. Conclusions SVM showed comparable yield and reduced false hit rates in searching large compound libraries compared to the similarity-based and other machine-learning VS methods developed from the same set of training compounds and molecular descriptors. We tested three virtual hits of the same novel scaffold from in-house chemical libraries not reported as Src inhibitor, one of which showed moderate activity. SVM may be potentially explored for searching Src inhibitors from large compound libraries at low false-hit rates.

Search and detection modeling of military imaging systems  

NASA Astrophysics Data System (ADS)

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

Yale Image Finder (YIF): a new search engine for retrieving biomedical images  

PubMed Central

Summary: Yale Image Finder (YIF) is a publicly accessible search engine featuring a new way of retrieving biomedical images and associated papers based on the text carried inside the images. Image queries can also be issued against the image caption, as well as words in the associated paper abstract and title. A typical search scenario using YIF is as follows: a user provides few search keywords and the most relevant images are returned and presented in the form of thumbnails. Users can click on the image of interest to retrieve the high resolution image. In addition, the search engine will provide two types of related images: those that appear in the same paper, and those from other papers with similar image content. Retrieved images link back to their source papers, allowing users to find related papers starting with an image of interest. Currently, YIF has indexed over 140 000 images from over 34 000 open access biomedical journal papers.

A simulated MS/MS library for spectrum-to-spectrum searching in large scale identification of proteins.  

PubMed

Identifying peptides from mass spectrometric fragmentation data (MS/MS spectra) using search strategies that map protein sequences to spectra is computationally expensive. An alternative strategy uses direct spectrum-to-spectrum matching against a reference library of previously observed MS/MS that has the advantage of evaluating matches using fragment ion intensities and other ion types than the simple set normally used. However, this approach is limited by the small sizes of the available peptide MS/MS libraries and the inability to evaluate the rate of false assignments. In this study, we observed good performance of simulated spectra generated by the kinetic model implemented in MassAnalyzer (Zhang, Z. (2004) Prediction of low-energy collision-induced dissociation spectra of peptides. Anal. Chem. 76, 3908-3922; Zhang, Z. (2005) Prediction of low-energy collision-induced dissociation spectra of peptides with three or more charges. Anal. Chem. 77, 6364-6373) as a substitute for the reference libraries used by the spectrum-to-spectrum search programs X!Hunter and BiblioSpec and similar results in comparison with the spectrum-to-sequence program Mascot. We also demonstrate the use of simulated spectra for searching against decoy sequences to estimate false discovery rates. Although we found lower score discrimination with spectrum-to-spectrum searches than with Mascot, particularly for higher charge forms, comparable peptide assignments with low false discovery rate were achieved by examining consensus between X!Hunter and Mascot, filtering results by mass accuracy, and ignoring score thresholds. Protein identification results are comparable to those achieved when evaluating consensus between Sequest and Mascot. Run times with large scale data sets using X!Hunter with the simulated spectral library are 7 times faster than Mascot and 80 times faster than Sequest with the human International Protein Index (IPI) database. We conclude that simulated spectral libraries greatly expand the search space available for spectrum-to-spectrum searching while enabling principled analyses and that the approach can be used in consensus strategies for large scale studies while reducing search times.

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

SciTech Connect

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

A Search for Vulcanoids Using STEREO Heliospheric Imager Data  

NASA Astrophysics Data System (ADS)

Over the past 20 years, our understanding of the solar system has grown dramatically, as a series of heretofore wholly or largely undetected populations of small bodies have been revealed in increasing detail. Among the few stable dynamical niches that remain relatively unexplored is the region interior to Mercury's orbit (specifically, orbits with semi-major axes between 0.07 and 0.21 AU), where a population of small, asteroid-like bodies called Vulcanoids is hypothesized to reside. We present the initial results from our campaign to use images from the Heliospheric Imagers aboard NASA's two STEREO spacecraft to conduct the most constraining search yet performed for Vulcanoids. In terms of photometric depth times the area covered, our campaign is over two orders of magnitude better than the previous best search. We are able to detect main-belt asteroids as faint as V=13.5 as they appear to transit through the Vulcanoid region. We have not yet detected any candidate Vulcanoids, although our search is still ongoing. We conservatively estimate the limiting magnitude of our search to be approximately V=13, meaning our search will be complete for Vulcanoids as small as 6.4 km in diameter at 0.21 AU and 2.2 km at 0.07 AU. At these limits, even the non-detection of any Vulcanoids will place new constraints on the formation and subsequent collisional and dynamical evolution of objects in the deep inner solar system.

A search of outer Trojans on ASTROVIRTEL images  

NASA Astrophysics Data System (ADS)

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

Composite filter trees and image recognition via binary search  

NASA Astrophysics Data System (ADS)

Construction rules for building composite binary phase-only filters (CBPOFs) designed for use at the nodes of a binary tree have been developed using upweighted superposition algorithms. This paper describes the use of this method to build a four-target, rotation-invariant CBPOF bank on which binary tree searches can be performed. Each of the four trees in this filter bank consists of 256 simple filters (BPOFs) and 254 composites. Sequential search of the 256 simple filters is replaced by a binary search which uses at most 26 composites and 4 simple BPOFs. An image recognition system utilizing the filter bank has been developed, assembled, and evaluated by simulation and experiment. The empirical results obtained using a hybrid optical correlator with computer-controlled magneto-optic spatial light modulators (MOSLMs) at the input and filter planes are presented.

Mapping coral reef benthic substrates using hyperspectral space-borne images and spectral libraries  

NASA Astrophysics Data System (ADS)

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

Mobile robot control for composition of seamless and high-resolution images in library  

NASA Astrophysics Data System (ADS)

We are developing an assistant robot system for administration of a library. In this system, an autonomous mobile robot obtains images with a camera, and composes seamless and high-resolution images of a bookshelf by using mosaicing and super-resolution techniques. In this paper, we propose a control method for the robot in front of a bookshelf as a part of this system. To obtain images that are suitable for mosaicing, a robot should take images from the same distance and orientation to a bookshelf. Our control method utilizes horizontal edges, which are detected easily in any bookshelf. The robot modifies its orientation with the edge in camera images. We implemented a super-resolution and mosaicing algorithm. Our implementation is simple. However, it can compose a high quality image in an experiment, since the robot obtains preferable images for the image processing.

Rapid development of medical imaging tools with open-source libraries.  

PubMed

Rapid prototyping is an important element in researching new imaging analysis techniques and developing custom medical applications. In the last ten years, the open source community and the number of open source libraries and freely available frameworks for biomedical research have grown significantly. What they offer are now considered standards in medical image analysis, computer-aided diagnosis, and medical visualization. A cursory review of the peer-reviewed literature in imaging informatics (indeed, in almost any information technology-dependent scientific discipline) indicates the current reliance on open source libraries to accelerate development and validation of processes and techniques. In this survey paper, we review and compare a few of the most successful open source libraries and frameworks for medical application development. Our dual intentions are to provide evidence that these approaches already constitute a vital and essential part of medical image analysis, diagnosis, and visualization and to motivate the reader to use open source libraries and software for rapid prototyping of medical applications and tools.

Image computing library for a next-generation VLIW multimedia processor  

NASA Astrophysics Data System (ADS)

We have developed the University of Washington Image Computing Library (UWICL), the high-performance image processing library for a next-generation mediaprocessor currently under development, named the Media Accelerated Processor (MAP1000). The primary goal of this library is to provide the algorithm developers and application programmers with a flexible and efficient library of core image computing functions. The UWICL is organized as a set of three hierarchical layers. Each function in this multilayered framework consists of an application module, a function module, and a tight-loop module. The MAP has an intelligent DMA controller called the Data Streamer that allows efficient data flow management. In cache-based architectures, streaming image data from the external memory generates many costly data-cache misses, in many cases leading to a severe performance bottleneck. The MAP's Data Streamer is designed to address this problem. To reduce the number of the data-cache misses further, a ping-ponging data flow scheme is employed in UWICL functions, i.e., while execution units are processing a block of data currently in the data cache, the Data Streamer brings the next data block to the data cache before it is actually needed. We compare the performance of key imaging functions on the MAP and the Texas Instruments TMS320C80, one of the most powerful mediaprocessors currently available. Typically, a MAP function is 1.5 to 6.6 times faster than the corresponding TMS320C80 implementation. Also, we demonstrate the advantages of the UWICL's multilayered library organization over the single-layered approach with an example in implementing the Canny's edge detector. The multilayered implementation of this algorithm outperforms the single- layered version by 26%.

Hierarchical Object Category Recognition Technique for Image Based Search System  

NASA Astrophysics Data System (ADS)

In this paper, we present an object category recognition method for an information search system which is queried by camera of mobile phone or by servers of internet services. In such a system, processing speed is an important requirement. To improve processing speed, the hierarchical object category recognition technique proposed by Serre(23) is modified using Haar-Like features, vector quantization of feature models, and reduction of processing area. In addition, by retaining the information of each feature's position, it compensates the accuracy which is a little reduced in exchange of processing speed. We implemented this method to web server, and proved this system can work in practical processing time. Through the experiment for Caltech-101 image database and natural scene category images, we also confirm the accuracy of our approach.

Narrow-band imaging and a search for planetary nebulae  

NASA Astrophysics Data System (ADS)

We summarize the results of narrow-band (H? and [\\O 3] lambda 5007 Angstroms) imaging of eight planetary nebulae taken during recent observing campaigns: We present the probably largest known PN, MWP 1, with a linear diameter of about 6 pc. We show first narrow-band images of He 2-437, MeWe 1-5, MeWe 1-8, MeWe 1-9, NGC 1360, and of - like we term them - the ``Galactic footballs'' A 43 and NGC 7094. We report about a search for planetary nebulae around eleven extremely hot (pre-) white dwarfs which had not been successful. Based on observations obtained at the German-Spanish Astronomical Center, Calar Alto, operated by the Max-Planck-Institut für Astronomie Heidelberg jointly with the Spanish National Commission for Astronomy and at the European Southern Observatory, La Silla, Chile.

Improving Web image search by bag-based reranking.  

PubMed

Given a textual query in traditional text-based image retrieval (TBIR), relevant images are to be reranked using visual features after the initial text-based search. In this paper, we propose a new bag-based reranking framework for large-scale TBIR. Specifically, we first cluster relevant images using both textual and visual features. By treating each cluster as a "bag" and the images in the bag as "instances," we formulate this problem as a multi-instance (MI) learning problem. MI learning methods such as mi-SVM can be readily incorporated into our bag-based reranking framework. Observing that at least a certain portion of a positive bag is of positive instances while a negative bag might also contain positive instances, we further use a more suitable generalized MI (GMI) setting for this application. To address the ambiguities on the instance labels in the positive and negative bags under this GMI setting, we develop a new method referred to as GMI-SVM to enhance retrieval performance by propagating the labels from the bag level to the instance level. To acquire bag annotations for (G)MI learning, we propose a bag ranking method to rank all the bags according to the defined bag ranking score. The top ranked bags are used as pseudopositive training bags, while pseudonegative training bags can be obtained by randomly sampling a few irrelevant images that are not associated with the textual query. Comprehensive experiments on the challenging real-world data set NUS-WIDE demonstrate our framework with automatic bag annotation can achieve the best performances compared with existing image reranking methods. Our experiments also demonstrate that GMI-SVM can achieve better performances when using the manually labeled training bags obtained from relevance feedback. PMID:21659029

A search for Vulcanoids with the STEREO Heliospheric Imager  

NASA Astrophysics Data System (ADS)

Interior to the orbit of Mercury, between 0.07 and 0.21 AU, is a dynamically stable region where a population of asteroids, known as Vulcanoids, may reside. We present the results from our search for Vulcanoids using archival data from the Heliospheric Imager-1 (HI-1) instrument on NASA's two STEREO spacecraft. Four separate observers independently searched through images obtained from 2008-12-10 to 2009-02-28. Roughly, all Vulcanoids with e ? 0.15 and i ? 15° will pass through the HI-1 field of view at least twice during this period. No Vulcanoids were detected. Based on the number of synthetic Vulcanoids added to the data that were detected, we derive a 3? upper limit (i.e. a confidence level >0.997) that there are presently no Vulcanoids larger than 5.7 km in diameter, assuming an R-band albedo of pR = 0.05 and a Mercury-like phase function. The present-day Vulcanoid population, if it exists at all, is likely a small remnant of the hypothetical primordial Vulcanoid population due to the combined effects of collisional evolution and subsequent radiative transport of collisional fragments. If we assume an extant Vulcanoid population with a collisional equilibrium differential size distribution with a power law index of -3.5, our limit implies that there are no more than 76 Vulcanoids larger than 1 km.

Exploiting chemical libraries, structure, and genomics in the search for kinase inhibitors.  

PubMed

Selective protein kinase inhibitors were developed on the basis of the unexpected binding mode of 2,6,9-trisubstituted purines to the adenosine triphosphate-binding site of the human cyclin-dependent kinase 2 (CDK2). By iterating chemical library synthesis and biological screening, potent inhibitors of the human CDK2-cyclin A kinase complex and of Saccharomyces cerevisiae Cdc28p were identified. The structural basis for the binding affinity and selectivity was determined by analysis of a three-dimensional crystal structure of a CDK2-inhibitor complex. The cellular effects of these compounds were characterized in mammalian cells and yeast. In the latter case the effects were characterized on a genome-wide scale by monitoring changes in messenger RNA levels in treated cells with high-density oligonucleotide probe arrays. Purine libraries could provide useful tools for analyzing a variety of signaling and regulatory pathways and may lead to the development of new therapeutics. PMID:9677190

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

NASA Astrophysics Data System (ADS)

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.

Establishment of a search library about benzylisoquinoline alkaloids based on selective separation on the binaphthyl column and standard analysis on C18 column.  

PubMed

A search library about benzylisoquinoline alkaloids was established based on preparation of alkaloid fractions from Rhizoma coptidis, Cortex phellodendri, and Rhizoma corydalis. In this work, two alkaloid fractions from each herbal medicine were first prepared based on selective separation on the "click" binaphthyl column. And then these alkaloid fractions were analyzed on C18 column by liquid chromatography coupled with tandem mass spectrometry. Many structure-related compounds were included in these alkaloids fractions, which led to easy separation and good MS response in further work. Therefore, a search library of 52 benzylisoquinoline alkaloids was established, which included eight aporphine, 19 tetrahydroprotoberberine, two protopine, two benzyltetrahydroisoquinoline, and 21 protoberberine alkaloids. The information of the search library contained compound names, structures, retention times, accurate masses, fragmentation pathways of benzylisoquionline alkaloids, and their sources from three herbal medicines. Using such a library, the alkaloids, especially those trace and unknown components in some herbal medicine could be accurately and quickly identified. In addition, the distribution of benzylisoquinoline alkaloids in the herbal medicines could be also summarized by searching the source samples in the library. PMID:23109405

Methane Imaging Search for Planetary Mass Objects in Rho Ophiuchi  

NASA Astrophysics Data System (ADS)

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

Visual Search with Image Modification in Age-Related Macular Degeneration  

PubMed Central

Purpose. AMD results in loss of central vision and a dependence on low-resolution peripheral vision. While many image enhancement techniques have been proposed, there is a lack of quantitative comparison of the effectiveness of enhancement. We developed a natural visual search task that uses patients' eye movements as a quantitative and functional measure of the efficacy of image modification. Methods. Eye movements of 17 patients (mean age = 77 years) with AMD were recorded while they searched for target objects in natural images. Eight different image modification methods were implemented and included manipulations of local image or edge contrast, color, and crowding. In a subsequent task, patients ranked their preference of the image modifications. Results. Within individual participants, there was no significant difference in search duration or accuracy across eight different image manipulations. When data were collapsed across all image modifications, a multivariate model identified six significant predictors for normalized search duration including scotoma size and acuity, as well as interactions among scotoma size, age, acuity, and contrast (P < 0.05). Additionally, an analysis of image statistics showed no correlation with search performance across all image modifications. Rank ordering of enhancement methods based on participants' preference revealed a trend that participants preferred the least modified images (P < 0.05). Conclusions. There was no quantitative effect of image modification on search performance. A better understanding of low- and high-level components of visual search in natural scenes is necessary to improve future attempts at image enhancement for low vision patients. Different search tasks may require alternative image modifications to improve patient functioning and performance.

Multimedia explorer: image database, image proxy-server and search-engine.  

PubMed Central

Multimedia plays a major role in medicine. Databases containing images, movies or other types of multimedia objects are increasing in number, especially on the WWW. However, no good retrieval mechanism or search engine currently exists to efficiently track down such multimedia sources in the vast of information provided by the WWW. Secondly, the tools for searching databases are usually not adapted to the properties of images. HTML pages do not allow complex searches. Therefore establishing a more comfortable retrieval involves the use of a higher programming level like JAVA. With this platform independent language it is possible to create extensions to commonly used web browsers. These applets offer a graphical user interface for high level navigation. We implemented a database using JAVA objects as the primary storage container which are then stored by a JAVA controlled ORACLE8 database. Navigation depends on a structured vocabulary enhanced by a semantic network. With this approach multimedia objects can be encapsulated within a logical module for quick data retrieval.

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

NASA Astrophysics Data System (ADS)

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

[Determination of 12 steroid hormone residues in pig tissues by liquid chromatography-tandem mass spectrometry combining with library search].  

PubMed

A method was developed for the simultaneous determination and identification of 12 steroid hormone residues in pig tissues, including stanolone, aldosterone, boldenone, danazol, metandienone, methyltestosterone, nadrolone, norethindrone, progesterone, stanozolol, testosterone and testosterone propionate, using liquid chromatography-tandem triple-quadrupole linear ion trap mass spectrometry(LC-MS/MS). Homogenized pig tissue samples were purified with a Waters MCX solid phase extraction column after enzymatic hydrolysis by beta-glucuronidase, then separated on a Venusil MP C18 column (100 mm x 2, 1 mm, 3 microm) using gradient elution with the mobile phases of acetonitrile and water with 0.1% (v/v) formic acid. A multiple reaction monitoring (MRM) as survey scan and an enhanced product ion (EPI) scan as dependent scan were performed in an information dependent acquisition (IDA) experiment. The compound identification was carried out by library search with a newly developed MS/MS library based on EPI spectra at three different collision energies in positive mode. The results showed that the limits of detection (LODs, S/N = 3) were in the range of 0.2 - 0.5 microg/kg for the steroid hormones, and with a good linearity (r > 0.99) ranged from 0.5 to 100.0 microg/L. The average recoveries (n = 6) of the 12 steroid hormones spiked in pig tissue samples at 5.0 microg/kg ranged from 72.0% to 98.1% with the relative standard deviations (RSDs) between 3.1% and 12.5%. The method was applied for the qualitative and quantitative determination of steroid hormone residues in pig tissues with sensitive and accurate characteristics. PMID:22128732

Enhancement of discontinuities in seismic 3-D images using a Java estimation library  

NASA Astrophysics Data System (ADS)

Seismic images are difficult to interpret. The nature of the seismic experiment and the ever present sedimentary layering of the subsurface result in oscillatory and complex 3-D seismic images In principle, computer programs can enhance geologically significant image features, such as faults, erosional surfaces, and salt boundaries. Standard edge enhancement, however, fails to compute useful seismic discontinuity maps. The correlation between an image region and its best-fitting local plane wave generates clear and discriminating maps for a wide range of images. A third approach, prediction-error filtering, yields detailed fault maps for images with sharp faults. For images with rather smooth fault zones, prediction error unfortunately fails. This dissertation's discontinuity computations are the first comprehensive application of a new innovative Java estimation library: Jest (Java for estimation). Jest comprises a general and extendible library for numerical optimization for science and engineering, Jam (Java and mathematics), and a particular extension of that framework for seismic image processing, Jag (Java and geophysics). Jest successfully separates optimization and application software. To ensure the compatibility of solver and application, Jest is built around a set of simple interfaces that define method invocations for the fundamental mathematical objects of numerical optimization, such as vectors, vector spaces, operators, and solvers. Jest's solvers are implemented in terms of these mathematical objects and, consequently, possess the generality of the original abstract mathematical algorithm. Finally, the dissertation is a reproducible electronic document, a simple software filing system that organizes, preserves, and potentially transfers the technology of any computational scientific research project. The document's central makefile offers readers four standard commands: burn removes the document's result figures, build recomputes them, view displays the figures, and clean removes any intermediate files. of these commands. Although we developed these standards to aid readers we discovered that authors are often the principal beneficiaries. In combination with the World Wide Web's ability to distribute software,. standardized reproducibility of computational research offers unprecedented opportunities for collaboration and learning. In particular, the combination of Java software (such as Jest) and the concept of reproducible documents, potentially enables any reader to reproduce a scientist's results at the push of a button in a World Wide Web browser.

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

A survey of medical students on the impact of a new digital imaging library in the dissection room.  

PubMed

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

Hyperspectral Image-Based Broad Area Search (HIBAS) Final Report Summary  

SciTech Connect

Two of the more important tasks faced by image analysts are broad area search and site monitoring. In each case, the objective is to detect occurrences of targets of interest (e.g., buildings, mobile targets of military significance, etc.). In broad area search, large swaths of countryside are imaged. In site monitoring, a number of smaller areas of interest are imaged multiple times. The crisis currently facing image analysts lies in their inability to analyze massive volumes of remotely sensed imagery in a time critical fashion. The problem has become more critical with technological advances that have enabled images of increasing size, resolution and dimensionality (such as monochrome images at higher spatial resolution--e.g., Digital Globe imagery--and hyperspectral images at higher spectral resolution) to be rapidly acquired.

Visual search performance of patients with vision impairment: Effect of JPEG image enhancement  

PubMed Central

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.

Focused library design in GPCR projects on the example of 5-HT(2c) agonists: comparison of structure-based virtual screening with ligand-based search methods.  

PubMed

The aim of this study was to investigate the usefulness of structure-based virtual screening (VS) for focused library design in G protein-coupled receptors (GPCR) projects on the example of 5-HT(2c) agonists. We compared the performance of structure-based VS against two different homology models using FRED for docking and ScreenScore, FlexX, and PMF for rescoring with the results of 12 ligand-based similarity searches using four different query compounds and three different similarity metrics (Daylight, FTree, Phacir). The result of the similarity search showed much variation, from an enrichment factor up to 3.2 to worse than random, whereas the structure-based VS gave a more stable result with a constant enrichment factor around 2. Additionally, actives retrieved by the structure-based approach were more diverse than the actives among the top scorers of the similarity searches. Based on these results, we suggest basing a focused library design for a GPCR project on a combination of a ligand-based similarity search and structure-based docking. PMID:16224780

The Vector, Signal, and Image Processing Library (VSIPL): an Open Standard for Astronomical Data Processing  

NASA Astrophysics Data System (ADS)

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

Automated search and retrieval of information from imaged documents using optical correlation techniques  

NASA Astrophysics Data System (ADS)

Litton PRC and Litton Data Systems Division are developing a system, the Imaged Document Optical Correlation and Conversion System (IDOCCS), to provide a total solution to the problem of managing and retrieving textual and graphic information from imaged document archives. At the heart of IDOCCS, optical correlation technology provides the search and retrieval of information from imaged documents. IDOCCS can be used to rapidly search for key words or phrases within the imaged document archives. In addition, IDOCCS can automatically compare an input document with the archived database to determine if it is a duplicate, thereby reducing the overall resources required to maintain and access the document database. Embedded graphics on imaged pages can also be exploited; e.g., imaged documents containing an agency's seal or logo can be singled out. In this paper, we present a description of IDOCCS as well as preliminary performance results and theoretical projections.

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

SciTech Connect

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

Search of temporal chaos in TV images of aurora  

NASA Astrophysics Data System (ADS)

Television (TV) data obtained during the development of an auroral form contain information about the spatial and temporal dynamics of the form generation. It is possible to investigate the spatial distribution of auroral luminosity in each image. Also, one can study the temporal dynamics of aurora using keograms or ``virtual photometers.'' In this report we investigate the temporal dynamics using information about the spatial distribution of auroral luminosity to define the metric in ``space of images.'' The algorithm of Grassberger-Procaccia has been applied to obtain the correlation dimension as a characteristic of the temporal chaos in sets of TV images of aurora. The approach has been applied to TV observations of pulsation aurora at Lovozero station.

Global Image Dissimilarity in Macaque Inferotemporal Cortex Predicts Human Visual Search Efficiency  

PubMed Central

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

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

Incorporating holistic visual search concepts into a SPECT myocardial perfusion imaging numerical observer  

NASA Astrophysics Data System (ADS)

Previous Single Photon Emission Computed Tomography (SPECT) myocardial perfusion imaging (MPI) research has explored the utility of numerical observers. One previous study proposed that the model of holistic visual search of a myocardial perfusion image by an expert human observer might improve the development of a SPECT MPI numerical observer. Further examination of numerical processing techniques that seem to be analogous to initial stage of human holistic image search has helped to further refine the numerical observer. The current numerical observer considers some fundamental issues in the refinement of the numerical observer: the need for background estimation, the determination of blobs and the 'search-like' selection of a few blobs for subsequent decision analysis.

Metrics of spectral image complexity with application to large area search  

NASA Astrophysics Data System (ADS)

Spectral image complexity is an ill-defined term that has been addressed previously in terms of dimensionality, multivariate normality, and other approaches. Here, we apply the concept of the linear mixture model to the question of spectral image complexity at spatially local scales. Essentially, the ``complexity'' of an image region is related to the volume of a convex set enclosing the data in the spectral space. The volume is estimated as a function of increasing dimensionality (through the use of a set of endmembers describing the data cloud) using the Gram Matrix approach. It is hypothesized that more complex regions of the image are composed of multiple, diverse materials and will thus occupy a larger volume in the hyperspace. The ultimate application here is large area image search without a priori information regarding the target signature. Instead, image cues will be provided based on local, relative estimates of the image complexity. The technique used to estimate the spectral image complexity is described and results are shown for representative image chips and a large area flightline of reflective hyperspectral imagery. The extension to the problem of large area search will then be described and results are shown for a 4-band multispectral image.

Cathodoluminescence : an imaging technique for the search of extraterrestrial life  

NASA Astrophysics Data System (ADS)

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

Toxicological screening of urine for drugs by liquid chromatography/time-of-flight mass spectrometry with automated target library search based on elemental formulas.  

PubMed

The present study describes a novel approach for utilizing liquid chromatography/time-of-flight mass spectrometry (LC/TOFMS) in qualitative screening analysis. An LC/TOFMS method was developed for screening toxicologically relevant substances in urine samples. After solid phase extraction and LC separation, the method included full spectrum acquisition followed by automatic internal calibration, searching against a target library, and reporting positive identifications. The target library, containing 433 toxicologically relevant substances in the mass range of 105-734 Da, was created simply by entering the elemental formulas of substances into the instrument software for the calculation of their respective monoisotopic masses. In addition to parent drugs, the library contained selected urinary drug metabolites, based on their structures available in the literature. Identification was based on the exact masses of the compounds. The LC/TOFMS method provided 5-10 ppm mass accuracy for a majority of identified compounds in authentic urine samples. Compared with established thin-layer and gas chromatographic methods, the LC/TOFMS method produced similar findings in urine with the additional advantage of metabolite identification without actual reference substances.

Design and clinical evaluation of a high-capacity digital image archival library and high-speed network for the replacement of cinefilm in the cardiac angiography environment  

NASA Astrophysics Data System (ADS)

An economical and practical digital solution for the replacement of 35 mm cine film as the archive media in the cardiac x-ray imaging environment has remained lacking to date due to the demanding requirements of high capacity, high acquisition rate, high transfer rate, and a need for application in a distributed environment. A clinical digital image library and network based on the D2 digital video format has been installed in the Duke University Cardiac Catheterization Laboratory. The system architecture includes a central image library with digital video recorders and robotic tape retrieval, three acquisition stations, and remote review stations connected via a serial image network. The library has a capacity for over 20,000 Gigabytes of uncompressed image data, equivalent to records for approximately 20,000 patients. Image acquisition in the clinical laboratories is via a real-time digital interface between the digital angiography system and a local digital recorder. Images are transferred to the library over the serial network at a rate of 14.3 Mbytes/sec and permanently stored for later review. The image library and network are currently undergoing a clinical comparison with cine film for visual and quantitative assessment of coronary artery disease. At the conclusion of the evaluation, the configuration will be expanded to include four additional catheterization laboratories and remote review stations throughout the hospital.

Imaging cytometry for counting circulating tumor cells: comparative analysis of the CellSearch vs ImageStream systems.  

PubMed

Circulating tumor cell (CTC) enumeration is important clinically for identifying prognostic and predictive factors in patients with solid cancers. The CellSearch device (Veridex) is an immunomagnetic CTC selection and enumeration system used in clinical practice. The ImageStream (Amnis) combines the strengths of flow cytometry and fluorescent microscopy in a single platform and has potential application for CTC counting. The performance in CTC enumeration was compared between the ImageStream and CellSearch systems. Various numbers of PANC-1 tumor cells were spiked into 7.5 mL of peripheral blood from a healthy donor. Before cell analysis by the ImageStream, tumor cell enrichment was performed by immunomagnetic selection with anti-EpPCAM. Anti-CD45 and anti-CK markers were used to discriminate between tumor cells and leukocytes. The ratios of tumor cells recovered from each dilution were calculated for both methods. The Wilcoxon rank test was applied to compare the results of the two methods and the reference value. The results of the two tested methods differed significantly from the reference value, but did not differ between them. Nevertheless, lower level of trueness and precision was observed in ImageStream when fewer numbers of CTCs were analyzed. Our results suggest that ImageStream platform for CTC enumeration has a potential value for the early diagnosis of disseminated disease, but needs an improvement of precision for the enumeration of low number of CTC.

Characterizing the development of visual search expertise in pathology residents viewing whole slide images.  

PubMed

The goal of this study was to examine and characterize changes in the ways that pathology residents examine digital whole slide images as they progress through the residency training. A series of 20 digitized breast biopsy whole slide images (half benign and half malignant biopsies) were individually shown to 4 pathology residents at four points in time--at the beginning of their first, second, third, and fourth years of residency. Their task was to examine each image and select three areas that they would most want to zoom in on in order to view the diagnostic detail at higher resolution. Eye position was recorded as they scanned each whole slide image at low magnification. The data indicate that with each successive year of experience, the residents' search patterns do change. Overall, with time, it takes significantly less time to view an individual slide and decide where to zoom, significantly fewer fixations are generated overall, and there is less examination of nondiagnostic areas. Essentially, the residents' search becomes much more efficient. These findings are similar to those in radiology, and support the theory that an important aspect of the development of expertise is improved pattern recognition (taking in more information during the initial Gestalt or gist view) as well as improved allocation of attention and visual processing resources. Progression in improvements in visual search strategies was similar, but not identical, for the 4 residents. PMID:22835956

FragVLib a free database mining software for generating "Fragment-based Virtual Library" using pocket similarity search of ligand-receptor complexes  

PubMed Central

Background With the exponential increase in the number of available ligand-receptor complexes, researchers are becoming more dedicated to mine these complexes to facilitate the drug design and development process. Therefore, we present FragVLib, free software which is developed as a tool for performing similarity search across database(s) of ligand-receptor complexes for identifying binding pockets which are similar to that of a target receptor. Results The search is based on 3D-geometric and chemical similarity of the atoms forming the binding pocket. For each match identified, the ligand's fragment(s) corresponding to that binding pocket are extracted, thus, forming a virtual library of fragments (FragVLib) that is useful for structure-based drug design. Conclusions An efficient algorithm is implemented in FragVLib to facilitate the pocket similarity search. The resulting fragments can be used for structure-based drug design tools such as Fragment-Based Lead Discovery (FBLD). They can also be used for finding bioisosteres and as an idea generator.

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

PubMed

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

Development of a multi-target screening analysis for 301 drugs using a QTrap liquid chromatography/tandem mass spectrometry system and automated library searching.  

PubMed

A new multi-target screening (MTS) procedure for drugs in blood and urine for toxicological analysis has been developed using a hybrid triple-quadrupole linear ion trap mass spectrometer (QTrap) for the fast detection and identification of 301 forensically important drugs, e.g. tranquilizers (benzodiazepines), hypnotics, drugs of abuse (opiates, cocaine, amphetamines, cannabinoids), antidepressants, neuroleptics, and some cardiac drugs, in one single liquid chromatography/tandem mass spectrometry (LC/MS/MS) analysis. Samples were extracted either with liquid-liquid extraction or solid-phase extraction. A multiple reaction monitoring (MRM) as survey scan and an enhanced product ion (EPI) scan as dependent scan were performed in an information-dependent acquisition (IDA) experiment. Finally, drug identification was carried out by library search with a newly developed MS/MS library based on EPI spectra at three different collision energies in positive mode. The advantage of this newly developed method is the possibility to detect and identify 301 drugs in one single LC/MS/MS run. PMID:15852450

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

NASA Astrophysics Data System (ADS)

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

Recent developments in imaging system assessment methodology, FROC analysis and the search model  

PubMed Central

A frequent problem in imaging is assessing whether a new imaging system is an improvement over an existing standard. Observer performance methods, in particular the receiver operating characteristic (ROC) paradigm, are widely used in this context. In ROC analysis lesion location information is not used and consequently scoring ambiguities can arise in tasks, such as nodule detection, involving finding localized lesions. This paper reviews progress in the free-response ROC (FROC) paradigm in which the observer marks and rates suspicious regions and the location information is used to determine whether lesions were correctly localized. Reviewed are FROC data analysis, a search-model for simulating FROC data, predictions of the model and a method for estimating the parameters. The search model parameters are physically meaningful quantities that can guide system optimization.

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

NASA Astrophysics Data System (ADS)

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.

The CT Image Library (CTIL) of the Lung Screening Study (LSS) network of the National Lung Screening Trial (NLST) consists of up to three annual screens using CT imaging from each of 17,308 participants with a significant history of smoking but no evidence of cancer at trial enrollment (Fall 2002-Spring 2004). Screens performed at numerous medical centers associated with 10 LSS-NLST screening centers are deidentified of protected health information and delivered to the CTIL via DVD, external hard disk, or Internet/Virtual Private Network transmission. The collection will be completed in late 2006. The CTIL is of potential interest to clinical researchers and software developers of nodule detection algorithms. Its attractiveness lies in its very specific, well-defined patient population, scanned via a common CT protocol, and in its collection of evenly spaced serial screens. In this work, we describe the technical details of the CTIL collection process from screening center retrieval through library storage. PMID:16783598

In vivo optical imaging of human lymphoma xenograft using a library-derived peptidomimetic against alpha4beta1 integrin.  

PubMed

Increasing literature suggests that cell adhesion molecule alpha4beta1 integrin plays a pivotal role in autoimmune diseases and cancer development. Noninvasive visualization of alpha4beta1 integrin in vivo will facilitate the understanding of its involvement in disease progression and development of targeted therapies. Due to the lack of high-affinity targeting ligands, molecular imaging of alpha4beta1 integrin is much less explored than that of alphavbeta3 and alphavbeta5 integrins. We have recently reported using the one bead-one compound combinatorial library method to identify a peptidomimetic, LLP2A, that preferentially binds to activated alpha4beta1 integrin. Here, we described the use of LLP2A-Cy5.5 conjugate as an in vivo optical imaging probe in a human lymphoma xenograft model. This univalent LLP2A-Cy5.5 conjugate retained the binding activity and specificity to alpha4beta1 integrin as shown by cell binding assays using alpha4beta1-positive Molt-4 T-leukemia cells. The subcutaneous Molt-4 tumor was clearly visualized from 1 to 24 h after tail vein injection of the conjugate. Direct imaging and confocal microscopic examination of excised tumors and organs confirmed the accumulation of LLP2A in tumors and revealed very little or no uptake in normal organs except for lymph nodes. Kidney uptake was high when the whole organ was scanned but it was negative when examined microscopically, suggesting that LLP2A bound to the renal tubules loosely. Tumor uptake of LLP2A-Cy5.5 conjugate was blocked by excess unlabeled LLP2A. This study showed that the combinatorial chemical library-derived peptidomimetic LLP2A can be easily developed into an optical imaging probe for noninvasively monitoring of activated alpha4beta1 integrin in vivo.

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

PubMed

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

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.

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

PubMed

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

The Impact of Transiting Planet Science on the Next Generation of Direct-Imaging Planet Searches  

NASA Astrophysics Data System (ADS)

Within the next five years, a number of direct-imaging planet search instruments, like the VLT SPHERE instrument, will be coming online. To successfully carry out their programs, these instruments will rely heavily on a-priori information on planet composition, atmosphere, and evolution. Transiting planet surveys, while covering a different semi-major axis regime, have the potential to provide critical foundations for these next-generation surveys. For example, improved information on planetary evolutionary tracks may significantly impact the insights that can be drawn from direct-imaging statistical data. Other high-impact results from transiting planet science include information on mass-to-radius relationships as well as atmospheric absorption bands. The marriage of transiting planet and direct-imaging results may eventually give us the first complete picture of planet migration, multiplicity, and general evolution.

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

NASA Astrophysics Data System (ADS)

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

A Search for Extremely Red Objects Using Archival WFPC2 Images  

NASA Astrophysics Data System (ADS)

To date HST/WFPC2 has imaged over 450 fields at intermediate and high galactic latitudes to a depth of I_c 26 mag {3Sigma in an 1Box^'' aperture} in the F814W filter. We propose an archival research program using these deep images in combination with ground-based K-band observations, to search for extremely red objects {EROs} with I_c - K > 5 and K < 19.0. We will survey roughly 1700 square arcminutes and expect to detect 68 bright EROs. The HST archive offers us two unique advantages to carry out an efficient survey: it provides a wealth of deep I-band images otherwise difficult to obtain from the ground, and the high resolution images will enable us to study in detail the distribution of ERO morphological types as a function of color. With the advent of large format near- IR detectors, imaging bright EROs in K-band over a large area is becoming efficient. In two years, this survey will produce the largest sample of bright EROs, useful for follow-up studies to determine the nature of EROs. Our ultimate goals are to 1}. measure the percentages of old elliptical and dusty starburst galaxies among the overall ERO population, setting strong constraints on theories of the formation and evolution of massive galaxies; 2}. determine how significant the starburst EROs contribute to the global star formation rate; and 3}. determine the relationship between EROs and the local ultra-luminous IRAS galaxies.

Search for temperature-related albedo changes in nightside and posteclipse images of Io  

NASA Astrophysics Data System (ADS)

Using an image-summing process that increases the visibility of Jupiter-lit surface features in Voyager images, we have produced the best-ever violet-filter image of the nightside of Io and the best-ever nightside/dayside brightness ratio map of this jovian moon. The ratio map shows no convincing evidence, on either global or local scales, of diurnal temperature-dependent albedo variations. We have also taken an image-ratioing technique developed by O'Shaughnessy et al. (1989), which those authors applied to Voyager violet-filter observations of one Io eclipse reappearance, and extended it to two other, higher-resolution Voyager posteclipse imaging sequences. In none of three imaging sequences do we find any isolated surface regions that convincingly exhibit posteclipse temperature-related albedo variations. These negative results suggest that on Io, pure cyclo-octasulfur (S8), and transient nighttime or in-eclipse deposits of SO2 frost, are at best limited to isolated areas smaller than the resolution of the images in use (i.e., smaller than a few tens of kilometers in size). Such limits are consistent with (1) the negative results reported by the majority of telescopic observers who have searched for posteclipse brightening of Io, (2) indications that physical processes in the ionian surface environment will change any S8 into other allotropes of sulfur, and (3) suggestions that Io's atmosphere is too thin to allow the deposition of transient, optically thick SO2 frost layers at nighttime or during eclipse.

The Pore3D library package for the textural analysis of X-ray computed microtomographic images of rocks  

NASA Astrophysics Data System (ADS)

Many research fields in Geosciences require the knowledge of the three-dimensional (3D) texture of rocks. X-ray computed microtomography (?CT) supplies an effective method to directly acquire 3D information. Transmission X-ray ?CT is a non-destructive technique based on the mapping of the linear attenuation coefficient of X-rays crossing the investigated sample. The 3D distribution of constituents and the contrast based on the different absorption properties of the components can be enhanced by phase-contrast imaging. On an X-ray tomographic dataset, if spatial resolution at the micron scale and proper software are available, a complete textural and morphological quantitative analysis can be carried out and a number of parameters can be extracted, including geometry and organization of discrete rock components (such as crystals, vesicles, fractures, alteration-compositional zones). In the case of volcanic rocks, ?CT can be used to image and quantify the textural and morphological characteristics of the rock constituents, such as vesicles (gas bubbles in solidified, erupted products), crystals and glass fibers. For pyroclastic rocks, investigated parameters to characterize the vesicle portion are the size distribution, geometry and orientation of the pores, the pore-throat size and organization, the pore-surface roughness and the topology of the overall pore and pore-throat network. In this work we present several procedures able to extract quantitative information from ?CT images of volcanic rocks. The imaging experiments have been carried out at the Elettra Synchrotron Light Laboratory in Trieste (Italy) using both the synchrotron radiation at the SYRMEP beamline and a custom-developed ?CT system, named TOMOLAB, equipped with a microfocus X-ray tube and based on a cone-beam geometry. The reconstructed 3D images (or volumes) have been elaborated with a software library, named Pore3D, custom-developed by the SYRMEP group at Elettra. The Pore3D software library allows a quantitative description of the morphology and topology of the sample components and it operates directly in the 3D domain, without inferring about the 3D behavior from stacked 2D information. The library has been elaborated to merge together in a common environment some of the features already available in previous research and commercial software, customizing in some cases their applications, adding new tools for the artifact reduction in the tomographic images and enhancing state-of-the-art methods for the quantitative analysis, as based on the specific know-how acquired by the SYRMEP group. The microtomographic experiments on selected pumices and scoriae have given us the opportunity to reconstruct and study the 3D internal structure of very different samples, originated at volcanoes with unique eruptive behavior and hazard potential. In particular, the analysis of vesicle size, shape, distribution, orientation and degree of interconnectivity, quantifies aspects that are directly related to the magma nature and dynamics. In fact, magma near the Earth's surface exists as a multiphase system, including gas bubbles and solid crystals in a liquid medium. The rheology of the magma and the processes that govern the transition between effusive and explosive eruptions can be fully understood if the gas permeability and flow through the bubble networks are quantified. As pyroclasts are natural records of the magma state, in terms of texture and composition, during the last phases of the conduit ascent, the textural 3D information can be coupled to physical, rheological and chemical properties of the parent magma.

Development of a handheld bistatic imaging sonar system for underwater search and survey  

NASA Astrophysics Data System (ADS)

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.

PubMed

The Internet provides a quick access to a plethora of the medical literature, in the form of journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualized, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Commercial web resources (Medscape, MedConnect, MedicineNet) add to the list of resource databases providing some of their content for open access. Several web-libraries (Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. Availability of specific dermatology-related websites (DermIs, DermNet, and Genamics Jornalseek) is useful addition to the ever growing list of web-based resources. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature and levels of detail available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine.

SPHERE-IFS: The spectro differential imager of the VLT for exoplanet search .  

NASA Astrophysics Data System (ADS)

The SPHERE is an exo-solar planet imager, which goal is to detect giant exo-solar planets in the vicinity of bright stars and to characterize them through spectroscopic and polarimetric observations. It is an complete system with a core made of an extreme-Adaptive Optics (AO) turbulence correction, pupil tracker and interferential coronagraphs. At its back end, a differential dual imaging camera and an integral field spectrograph (IFS) work in the Near Infrared (NIR) Y, J, H and Ks bands (0.95 - 2.32microns) and a high resolution polarization camera covers the visible (0.6 - 0.9microns). The IFS is a low resolution spectrograph (R 50) which works in the near IR (0.95 - 1.6microns), an ideal wavelength range for the detection of planetary features. In our baseline design the IFU is a new philosophy micro-lens array of about 145x145 elements designed to reduce as low as possible the contrast. The IFU will cover a field of view of about 1.7 x 1.7 square arcsecs reaching a contrast of 10-7, giving an high contrast and high spatial resolution ``imager'' able to search for planet well inside the star PSF. Currently in the first phase of integration IFS will see the first light at ESO Paranal, as VLT II generations instruments, in the Q3 2011.

Effect of image enhancement on the search and detection task in the urban terrain  

NASA Astrophysics Data System (ADS)

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.

Mammographic CADx system using an image library with an intelligent agent: a pattern matching approach  

NASA Astrophysics Data System (ADS)

It is conceivable that a comprehensive clinical case library with intelligent agents can sort and render clinically similar cases and present clinically significant features to assist the radiologist in interpreting mammograms. In this study, we used a deformable vector diagram as the primary framework for matching the mammographic masses. The vector diagram provides gradient and shape features of the mass. The deformable algorithm allows flexible matching. The vector diagram was also incorporated with our newly developed delineation method using steepest changes of a probability based cost-function. Thus it allows us to automatically extract the main body and significant part of border region for pattern matching using a weighted mutual information technique. We have collected 86 mammograms. Of these cases, 46 contain a benign mass and the other 40 contain a malignant mass. Using the weighted mutual information technique on the vector diagram of the mass region, we found that the benign masses can be sorted into 6 groups except one case; the malignant masses can be sorted into 8 groups except two cases. For all 86 cases, the masses can be sorted into 13 groups except three cases. In addition, one group of benign masses and one group of malignant mass cases merged into one which contains 10 cases. Hence, the success sorting rate was 85.7% (12/14) in terms of group and was 84.9% (73/86) in terms of case, respectively.

A High-Contrast Imaging Survey of SIM Lite Planet Search Targets  

NASA Astrophysics Data System (ADS)

With the development of extreme high contrast ground-based adaptive optics instruments and space missions aimed at detecting and characterizing Jupiter- and terrestrial-mass planets, it is critical that each target star be thoroughly vetted to determine whether it is a viable target, given both the instrumental design and scientific goals of the program. With this in mind, we have conducted a high-contrast imaging survey of mature AFGKM stars with the PALAO/PHARO instrument on the Palomar 200 inch telescope. The survey reached sensitivities sufficient to detect brown dwarf companions at separations of >50 AU. The results of this survey will be utilized both by future direct imaging projects such as GPI, SPHERE, and P1640 and indirect detection missions such as SIM Lite. Out of 84 targets, all but one have no close-in (0.45-1") companions and 64 (76%) have no stars at all within the 25" field of view. The sensitivity contrasts in the Ks passband ranged from 4.5 to 10 for this set of observations. These stars were selected as the best nearby targets for habitable planet searches because of their long-lived habitable zones (>1 billion years). We report two stars, GJ 454 and GJ 1020, with previously unpublished proper motion companions. In both cases, the companions are stellar in nature and are most likely M dwarfs based on their absolute magnitudes and colors. Based on our mass sensitivities and level of completeness, we can place an upper limit of ˜17% on the presence of brown dwarf companions with masses >40 MJ at separations of >1". We also discuss the importance of including statistics on those stars with no detected companions in their field of view for the sake of future companion searches and an overall understanding of the population of low-mass objects around nearby stars.

Digital Library for the Decorative Arts and Material Culture: Image and Text Collections  

NSDL National Science Digital Library

The decorative arts and material culture get their full due at this lovely online collection created by the University of Wisconsin's Digital Collections program. With generous funding from the Chipstone Foundation, the staff members at the Digital Collections program have digitized a variety of primary and secondary resources related to the decorative arts, with a particular focus on Early America. The materials offered here for consideration include items from the Chipstone ceramics and furniture collection and a number of important early documents, such as "The Gentleman and Cabinet-Maker's Director" from 1754 and Humphry Repton's 1794 work, "Sketches and hints on landscape gardening". The site includes several dozens other works, and visitors can also look through all of the materials via a sophisticated search engine.

Electronic Biomedical Literature Search for Budding Researcher  

PubMed Central

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.

An efficient search strategy for block motion estimation using image features  

Microsoft Academic Search

Block motion estimation using the exhaustive full search is computationally intensive. Fast search algorithms offered in the past tend to reduce the amount of computation by limiting the number of locations to be searched. Nearly all of these algorithms rely on this assumption: the MAD distortion function increases monotonically as the search location moves away from the global minimum. Essentially,

A new hospital library: a marketing opportunity.  

PubMed Central

A new or remodeled library presents a unique marketing opportunity for the hospital librarian. Furthermore, a well-designed library markets itself through its convenience, attractiveness, and ease of use. A marketing approach to library planning takes into account needs of users and of library staff and considers the librarian's relations with the architect as well as with hospital employees. This paper describes ways to combine library planning with marketing techniques and specifies aspects of the library that contribute to its good image.

Policy Library  

NSDL National Science Digital Library

A nonprofit and nonpartisan enterprise, the Policy Library seeks to "place public policy knowledge in the public domain." It does this by linking to an array of policy papers and resources available for free from think tanks, governments, and universities. The focus is on UK think tanks, but visitors will find content from a range of international organizations. The database currently contains over 700 policy and research papers, with additions made daily. Papers may be keyword searched by subject, author, country, institution, or title or browsed by topic under four categories: social policy, economic policy, international issues, and political thought. Each topical resource page also includes a varying number of related links. This is a solid resource that should find ready use by researchers, students, and the interested public.

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

NASA Astrophysics Data System (ADS)

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.

Large Spectral Library Problem  

SciTech Connect

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

Imaging techniques play an important role in evaluating the complex anatomy of bone and soft tissues of the wrist. The standard wrist radiographs and specialized views still form a very important imaging modality to unravel the wrist pathology in their simplest forms. This article discusses the routine radiography of the wrist followed by ancillary views and dynamic studies for each of the routine view described that helps reveal both static and dynamic pathologies. The literature search was carried out using the search strings or key words, and the databases were searched using the time frame of 1990 to 2011 that included Scopus, MD consult, Web of Knowledge, Pub Med, Ovid Medline and Cochrane Library. The print journals and books available at Manipal University library were hand searched and secondary search was done for the relevant articles included in the references of primary articles. Full articles as well as abstracts were used for the review.

A library of Lick Observatory Image Dissector Scanner indices for binary stellar populations  

NASA Astrophysics Data System (ADS)

Using evolutionary population synthesis, we present 13 refined absorption-line indices defined by the Lick Observatory Image Dissector Scanner (Lick/IDS) system for an extensive set of instantaneous-burst binary stellar populations (BSPs) at high resolution (~0.3 Å), and 38 indices at intermediate resolution (3 Å). The ages of the populations are at an interval of 1Gyr in the range 1-15Gyr, and the metallicities are in the range 0.004-0.03. These indices are obtained by two methods: (i) using the empirical fitting functions (FFs method); (ii) measured directly from the synthetic spectra (DC method). Together with our previous paper, a data base of Lick/IDS spectral absorption-line indices for BSPs at high and intermediate resolutions is provided. This set of indices includes 21 indices of Worthey et al., four Balmer indices defined by Worthey & Ottaviani, and 13 indices with the new passband definitions of Trager et al. The full set of synthetic indices and the integrated pseudo-continuum are listed in the Appendices, which are only available online at http://www.blackwell-synergy.com/ or from our website (http://www.ast9.com/), or on request from the first author. Moreover, the full set of the integrated spectral energy distributions can be obtained from our website. We compare the synthetic Lick/IDS indices obtained by the FFs method and those by the DC method for BSPs with various metallicities, and find that the discrepancies are significant: Ca4455 (index 6), Fe4668 (8), Mgb (13), Fe5709 (17), NaD (19), TiO1 (20) and TiO2 (21, except for Z = 0.02) in the W94 system, Ca4455T (6T), C24668T (8T), NaDT (19T), TiOT1 (20T) and TiOT2 (21T, except for Z = 0.02) in the T98 system obtained by the DC method are less (bluer) than the corresponding ones obtained by the FFs method for all metallicities. Ca4227 (index 3), Fe5782 (18), Ca4227T (3T) and Fe5782T (18T) are greater at Z = 0.03 and become bluer at Z = 0.004; the Fe5709T (17T) index is less at Z = 0.03 and becomes redder at Z = 0.004 than the corresponding ones obtained by the FFs method.

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

NASA Astrophysics Data System (ADS)

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

NSDL National Science Digital Library

ILEJ is a joint project by the Universities of Birmingham, Leeds, Manchester and Oxford, conducted under the auspice of the eLib (Electronic Libraries) Programme (discussed in the Scout Report for September 20, 1996). The project has digitized selected twenty-year runs of three eighteenth- and three nineteenth-century journals and placed the images online at the site. Journals include: Annual Register (1758-78), Gentleman's Magazine (1731-50), Philosophical Transactions of the Royal Society (1757-77), Blackwood's Edinburgh Magazine (1843-52), Notes and Queries (1849-69), and The Builder (1843-9). Users can browse the journals by volume and section, conduct a standard search, or try a "fuzzy search" (limited availability). The project has considerable potential for scholars and students of British history and literature, although slow loading image pages may make it more useful as an online index to these journals.

Scattering and Absorption Properties of Porous Dust Grains: A Library for Modeling the HST Optical and near-Infrared Scattered Light Images of Protopl  

NASA Astrophysics Data System (ADS)

We propose a theoretical program to calculate the scattering and absorption properties of porous dust grains grown by coagulation in protoplanetary disks, using the powerful discrete dipole approximation code DDSCAT which can accurately calculate the scattering properties of porous aggregates. This program will create a web-based library of scattering and absorption cross sections, and albedos, asymmetry parameters and phase functions for porous dust as a function of grain size, porosity and wavelength. This library will be made publicly available via the WWW at http://www.missouri.edu/~lia/. These scattering parameters are essential for interpreting the scattered light images of protoplanetary and debris disks in the visible and near-infrared wavelengths obtained with HST, allowing us to reliably determine the disk geometry and dust size distribution. The latter is of particular astrophysical significance since it can tell us whether grain growth -- the first stage of planet formation -- has indeed occurred in protoplanetary disks.

Searching for ULF signatures of the cusp: Observations from search coil magnetometers and auroral imagers in Svalbard  

NASA Astrophysics Data System (ADS)

Spacecraft traveling through the cusp at a variety of altitudes have consistently found the cusp to be filled with intense, often irregular power in the upper ULF frequency range. Some ground-based studies have observed narrowband waves in this same frequency range in the vicinity of the cusp foot point, but it has not been possible with magnetometers alone to either confirm or deny a cusp source for these waves. We report here on the first simultaneous, collocated observations of a set of induction magnetometers installed at three near-cusp sites on Svalbard and an all-sky auroral imager located at Longyearbyen. Data during northern winters of 2006-2007 and 2007-2008, when the cusp foot point was in darkness, showed occasional broadband noise when energetic particle precipitation occurred overhead, but on most days no broadband ULF power was observed above the noise level near noon when only soft cusp precipitation or poleward moving auroral forms occurred overhead. However, on 3 days, including 15 January 2007, several bursts of band-limited Pc 1-2 waves were observed in association with regions of intense soft precipitation that peaked near the poleward edge of the cusp. Their properties are consistent with an origin in the plasma mantle, as observed in a recent satellite-ground study by Engebretson et al. (2005). These observations confirm that even intense cusp precipitation is not effective in generating ion cyclotron waves that penetrate to the ground, if it is embedded within the central regions of the cusp, whereas regions of enhanced precipitation at the poleward edge of the cusp are associated with observed waves.

Searching for ULF signatures of the Cusp: Observations from search coil magnetometers and auroral imagers in Svalbard  

NASA Astrophysics Data System (ADS)

Spacecraft traveling through the cusp at altitudes ranging from near the magnetopause to just above the ionosphere have consistently found the cusp to be filled with intense but irregular power in both electric and magnetic fields in the upper ULF frequency range (up to at least 4 Hz). Ground-based induction magnetometers have for many years observed Pc 1-2 (electromagnetic ion cyclotron) waves in this same frequency range at various latitudes including near the footpoint of the cusp, but it has not been possible with magnetometers alone to either confirm or deny a cusp source for any of these waves, partly because of the occurrence of horizontal ducting of these waves in the ionosphere. We report here on the first simultaneous, collocated observations of a set of induction magnetometers installed at three sites on Svalbard (Longyearbyen, Ny Alesund, and Hornsund), and auroral imagers also located at the first two of these sites. Data during northern winter 2006-2007, when the cusp footpoint was in darkness, showed occasional narrowband Pc 1-2 wave events, frequent broadband noise when energetic particle precipitation occurred overhead, but the consistent absence of broadband ULF power above the noise level when only soft cusp precipitation was overhead. The intensity of narrowband Pc 1-2 wave events most often increased toward lower latitudes, consistent with wave sources on closed field lines. However, on one day when the cusp was observed to be equatorward of Longyearbyen, band-limited Pc 1-2 wave power was strongest at Ny Alesund, the northernmost station. This latter observation is consistent with waves originating in the plasma mantle just poleward of the cusp, as was found in a recent study using the Polar satellite and more widely spaced ground-based ULF observations by Engebretson et al. [2005], and again suggests that the cusp proper is not the source of any narrowband Pc 1-2 wave activity that can be observed on the ground, and little if any broadband activity as well.

Life After Press: The Role of the Picture Library in Communicating Astronomy to the Public  

NASA Astrophysics Data System (ADS)

Science communication is increasingly led by the image, providing opportunities for 'visual' disciplines such as astronomy to receive greater public exposure. In consequence, there is a huge demand for good and exciting images within the publishing media. The picture library is a conduit linking image makers of all kinds to image buyers of all kinds. The image maker benefits from the exposure of their pictures to the people who want to use them, with minimal time investment, and with the safeguards of effective rights management. The image buyer benefits from a wide choice of images available from a single point of contact, stored in a database that offers a choice between subject-based and conceptual searches. By forming this link between astronomer, professional or amateur, and the publishing media, the picture library helps to make the wonders of astronomy visible to a wider public audience.

WCSTools: Image Astrometry Toolkit  

NASA Astrophysics Data System (ADS)

WCSTools is a package of programs and a library of utility subroutines for setting and using the world coordinate systems (WCS) in the headers of the most common astronomical image formats, FITS and IRAF .imh, to relate image pixels to sky coordinates. In addition to dealing with image WCS information, WCSTools has extensive catalog search, image header manipulation, and coordinate and time conversion tasks. This software is all written in very portable C, so it should compile and run on any computer with a C compiler.

Segmentation of knee joints in x-ray images using decomposition-based sweeping and graph search  

NASA Astrophysics Data System (ADS)

Plain radiography (i.e., X-ray imaging) provides an effective and economical imaging modality for diagnosing knee illnesses and injuries. Automatically segmenting and analyzing knee radiographs is a challenging problem. In this paper, we present a new approach for accurately segmenting the knee joint in X-ray images. We first use the Gaussian high-pass filter to remove homogeneous regions which are unlikely to appear on bone contours. We then presegment the bones and develop a novel decomposition-based sweeping algorithm for extracting bone contour topology from the filtered skeletonized images. Our sweeping algorithm decomposes the bone structures into several relatively simple components and deals with each component separately based on its geometric characteristics using a sweeping strategy. Utilizing the presegmentation, we construct a graph to model the bone topology and apply an optimal graph search algorithm to optimize the segmentation results (with respect to our cost function defined on the bone boundaries). Our segmented results match well with the manual tracing results by radiologists. Our segmentation approach can be a valuable tool for assisting radiologists and X-ray technologists in clinical practice and training.

Design of fluorescence dye-conjugated peptides for the receptor-targeted optical imaging of tumors using solid-phase peptide libraries  

NASA Astrophysics Data System (ADS)

We describe the design and properties of cyanine dye-peptide conjugates synthesized on solid supports for screening assays. With this approach, we demonstrate the feasibility of including a diagnostic molecule into a spot synthesis of membrane-bound peptide libraries in order to permit screening of complete dye-peptide conjugates for their potential as fluorescent contrast agents in biomedical optical imaging. A cellulose support, which is modified with a linker permitting cleavage of the dye-peptide conjugates from the support, was prepared. The attachment of dyes to the peptides is exemplified with carboxy-substituted indotricarbocyanines, which can be covalently linked to the N-terminal amino group or a lysin in the course of the synthesis. Several dye-peptide conjugates were obtained by automated peptide synthesis on resins. Furthermore, model sequences consisting of up to 11 amino acids were synthesized on cellulose in sufficient amounts and purity, thus permitting direct testing of these compounds in cell- based assays and fluorescence microscopy. The dyes show only negligible alterations in their absorption and fluorescence properties when attached to low molecular weight peptides. In conclusion, membrane-bound peptide libraries provide a powerful tool to generate large diversities of dye-labeled peptides and to make these compounds available for biological screening assays.

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

PubMed Central

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

In this paper, we propose a novel framework for the web-based retrieval of Chinese calligraphic manuscript images which includes two main components: 1). A Shape- Similarity (SS)-based method which is to effectively support a retrieval over large Chinese calligraphic manuscript databases [19]. In this retrieval method, shapes of calligraphic characters are represented by their approximate contour points extracted from the character images; 2). To speed up the retrieval efficiency, we then propose a Composite - Distance- Tree(CD-Tree)-based high-dimensional indexing scheme for it. Comprehensive experiments are conducted to testify the effectiveness and efficiency of our proposed retrieval and indexing methods respectively.

Mean time for target acquisition in collaborative search with multiple imaging sensors  

NASA Astrophysics Data System (ADS)

In this paper the mean time to acquire a stationary target by n stationary imaging sensors is computed using probability theory by making use of the well established result that the detection time for a single imaging sensor is a random variable from an exponential probability density function. Each imaging sensor is characterized by a separate P? value which describes the probability an observer using that sensor will eventually acquire the target and a separate t value which describes the mean time to acquire the target using that sensor. There is no restriction on the wavelength band used by the imaging sensor. There are no empirical constants in the model presented here and the results are in agreement with and generalize previously published equations. The newly developed equations have been verified by numerical simulations and also yield the expected mean detection time for all limiting values of the input parameters. The code used in the numerical simulations is exhibited. For any given scenario, the separate ? observer-sensor-target parameters P? and t can be estimated using the NV-IPM model or measured in perception experiments. Thus the input parameters needed by the model are generally available. Comparing results presented here with results from war game simulations such as OneSAF may improve the quality of both products.

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

SciTech Connect

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

A Search for Core-Collapse Supernova Progenitors In Hubble Space Telescope Images  

NASA Astrophysics Data System (ADS)

Identifying the massive progenitor stars that give rise to core-collapse supernovae (SNe) is one of the main pursuits of supernova and stellar evolution studies. Using ground-based images of recent, nearby SNe obtained primarily with the Katzman Automatic Imaging Telescope, astrometry from 2MASS, and archival images from the Hubble Space Telescope, we have attempted the direct identification of the progenitors of 16 Type II and Type Ib/c SNe. We may have identified the progenitors of the Type II SNe 1999br, 1999ev, and 2001du, the Type Ib SNe 2001B and 2001is, and the Type Ic SN 1999bu, more than doubling the number of known SN progenitors. Additionally, we have recovered at late times SNe 1999dn, 2000C, and 2000ew, although none of these had detectable progenitors on pre-SN images. In fact, for the remaining SNe only limits can be placed on the absolute magnitude and color (when available) of the progenitor. The detected Type II SN progenitors and limits are consistent with red supergiants as progenitor stars, although possibly not as red as we had expected. Our results for the Type Ib/c SNe do not strongly constrain either Wolf-Rayet stars or massive interacting binary systems as progenitors. A.V.F.'s UC Berkeley group is supported by NSF grant AST-9987438, by the Sylvia and Jim Katzman Foundation, and by NASA grants AR-8754, AR-9529, and GO-8602 from STScI, operated by AURA, Inc., under NASA contract NAS5-26555.

Search for Periodicity in Image Sequences from the Yokoh Soft X-Ray Telescope  

NASA Astrophysics Data System (ADS)

The process by which the Sun's corona is heated is not well known. A leading model is the resonant absorption of Alfvénic surface waves. In order to be efficient as a heating mechanism, this process depends on the surface waves being well matched ot the length of the coronal loop through the condition of global-mode resonance: $v_{Alfv\\acute{e}n}$ = 2L/period (Davila, 1987). The Yohkoh Soft X-Ray Telescope (SXT) provides a means of recording the behavior and evolution of structures in the solar corona. Relatively fast-cadence sequences of CCD images become movies depicting the changing conditions in the X-ray emitting regions. By using software provided by the Yohkoh science team to measure the brightness of a selected subset of pixels in all the images of a movie, we can generate an X-ray light curve of a small portion of a given coronal structure. For the present dissertation, a number of SXT image sequences were selected from the Yohkoh archives. Light curves were generated in the manner outlined above, and these light curves were then examined for periodic modulations. It is shown that periodic modulations of X-ray brightness were detected with amplitudes of nearly 1\\%, and that the speeds inferred from interpreting these oscillations as global-mode resonance are in the neighborhood of 1800 -- 14000 km/s, consistent with Alfvén wave speeds but much higher than sound speeds implied by the temperatures measured from the images. The wave speeds and the modulation amplitudes imply plasma beta values in the range $\\beta_p \\approx 10^{-3} -- 10^{-2}$. (SECTION: Dissertation Summaries)

Cuneiform Digital Library Initiative  

NSDL National Science Digital Library

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

Remote access to electronic library services through a campus network.  

PubMed

The Health Science Library at University of Tennessee (UT), Memphis has taken advantage of a campuswide network for the purpose of providing enhanced access to library services. With a terminal or microcomputer, members of the UT Memphis community can use an electronic menu system to complete photocopy, interlibrary loan, and computer literature search request forms; leave messages or sign up for library workshops; use electronic mail to receive citations and abstracts from computer literature searches; use an electronic bulletin board to scan the library's new acquisitions lists, library hours, services, and policies; and use bibliographic retrieval software to search the library's locally mounted databases. Remote access to library services and electronic resources, which is available twenty-four hours a day, could potentially save users time and the institution money. Remote access, however, is intended to supplement, not to supplant or discourage, in-house library use. PMID:1998820

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

SciTech Connect

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

NSDL National Science Digital Library

Created by the University of Hawai'i System Libraries, this site contains three collections of digitized images. The first features images of Hawaiian language newspapers published from 1834 to 1948. They include stories, photos, advertisements, letters to the editor, and other content. The quality of images varies. The second collection comes from the Hawai'i War Records Depository (HWRD), and in addition to the photos, this section also provides information on the holdings of the HWRD, contact information, and a link to an online catalog. The third, and largest, collection includes approximately 8,000 images from the Trust Territory of the Pacific Islands (TTPI) archives. The photos are browsed by "reel" number and are offered as large thumbnails with links to full-size JPEG or TIFF images. The photos may also be keyword searched using an internal search engine. Links to further information about the four separate, self-governing districts that once composed the TTPI are also provided.

Recent health sciences library building projects.  

PubMed Central

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

The New Zealand Digital Library  

NSDL National Science Digital Library

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

Searching early bone metastasis on plain radiography by using digital imaging processing  

NASA Astrophysics Data System (ADS)

Some authors mention that it is not possible to detect early bone metastasis on plain radiography. In this work we use digital imaging processing to analyze three radiographs taken from a patient with bone metastasis discomfort on the right shoulder. The time period among the first and second radiography was approximately one month and between the first and the third one year. This procedure is a first approach in order to know if in this particular case it was possible to detect an early bone metastasis. The obtained results suggest that by carrying out a digital processing is possible to detect the metastasis since the radiography contains the information although visually it is not possible to observe it.

Piercing the Glare: A Direct Imaging Search for Planets in the Sirius System  

NASA Astrophysics Data System (ADS)

Astrometric monitoring of the Sirius binary system over the past century has yielded several predictions for an unseen third system component, the most recent one suggesting a lsim50 M Jup object in a ~6.3 year orbit around Sirius A. Here we present two epochs of high-contrast imaging observations performed with Subaru IRCS and AO188 in the 4.05 ?m narrowband Br ? filter. These data surpass previous observations by an order of magnitude in detectable companion mass, allowing us to probe the relevant separation range down to the planetary-mass regime (6-12 M Jup at 1'', 2-4 M Jup at 2'', and 1.6 M Jup beyond 4''). We complement these data with one epoch of M-band observations from MMT/AO Clio, which reach comparable performance. No data set reveals any companion candidates above the 5? level, allowing us to refute the existence of Sirius C as suggested by the previous astrometric analysis. Furthermore, our Br ? photometry of Sirius B confirms the lack of an infrared excess beyond the white dwarf's blackbody spectrum. Based on data collected at Subaru Telescope, which is operated by the National Astronomical Observatory of Japan, and at the MMT Observatory, a joint facility of the University of Arizona and the Smithsonian Institution.

A Fabry-Perot Imaging Search for Lyman-alpha Emission in Quasar Absorbers at z 2.4  

NASA Astrophysics Data System (ADS)

We have carried out a deep narrow-band imaging survey of six fields with heavy-element quasar absorption lines, using the Goddard Fabry Perot system at the Apache Point Observatory 3.5-meter telescope. The aim of these observations was to search for redshifted Ly-alpha emission from the galaxies underlying the absorbers at z = 2.3-2.5 and their companion galaxies. A few compact sources were discovered, but no significant diffuse Ly-alpha emitters were detected. Our observations suggest that the star formation rates in most of the absorbers in our sample are less than 1-2 Mo/yr, or that the Lyman-alpha flux is extinguished by dust within the absorber galaxies. We compare our results with those compiled from the literature and with predictions based on models of cosmic chemical evolution. VPK, DGT, and JM acknowledge support from NSF grant AST-0206197 and from the Univ. of South Carolina Research Foundation.

KEOPS: Kiloparsec Explorer for Optical Planet Search, a direct-imaging optical array at Dome C of Antarctica  

NASA Astrophysics Data System (ADS)

Recent site seeing testing campaigns conducted by our team from University of Nice1 show that Dome C represents the best site on Earth for astronomical high angular resolution (HAR) observations at optical and IR wavelengths. The dramatic gain over relevant HAR parameters r0, L0, ?0 and ?0, added to very low temperatures during the polar winter nights (-70°C), the dry atmosphere and the possibility of continuous observations during several nights make Dome C the ideal site for deploying a kilometric optical interferometer before the 2015 horizon. Here we describe the concept of Kiloparsec Explorer for Optical Planet Search (KEOPS) that is studied by our group at LUAN. KEOPS is an interferometric array of 36 off-axis telescopes, each 1.5m in diameter. Its kilometric baselines open sub-mas snap-shot imaging possibilities to detect and characterize extra-solar planetary systems, especially exo-Earths out to 300 parsecs from the visible to the thermal IR. KEOPS can be considered as a DARWIN/TPF challenger but at a much lower cost.

New Zealand Digital Library: Humanity Development Library 2.0  

NSDL National Science Digital Library

The mission of the Humanity Development Library is to make practical information from many sources available at the lowest possible cost to the user. Originally created as a set of CD-ROMs and now on the Web, the library provides a gateway to the publications of a whole host of international human development and educational organizations, from the Asian Cultural Centre for UNESCO (ACCU) to the World Bank. Greenstone software, developed for the New Zealand Digital Library, allows keyword searching across the 1,200+ texts in the library. Users can also browse by subject, title, or organization. The library is available as part of the New Zealand Digital Library, includes full texts and cover art of publications such as CERES, a periodical from the Food and Agriculture Organization of the United Nations, and AIDS Prevention Through Health Promotion, a 1991 book from the World Health Organization. The "Detach" feature of the software allows users to read selected publications in a separate browser window

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.
