Special Issue of the IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE on Digital libraries: Representation and Retrieval Papers are solicited for a special issue of the IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE which will address the subject of Digital libraries: Representation and Retrieval. The Guest Editors for the special issue will be Rosalind W. Picard and Alex P. Pentland, both of the M.I.T. Media Laboratory, USA. With the rapid increase in worldwide networks, people will soon have access to massive libraries of digital text, sound, image, video and other special-purpose data. The biggest obstacle to this ``information glut'' is that the technology for organizing, querying, and retrieving data from these multimedia libraries is still in its infancy. Research in pattern analysis and machine intelligence is needed to provide tools for accessing the content of these databases. The papers in this special issue will describing novel and significant tools and techniques that facilitate access to the content of large data collections. Manuscripts will not be accepted if they have been previously published, or if they describe algorithms that have not been carefully evaluated on large databases. Possible topics for papers submitted to the special issue include, but are not limited to: * Robust recognition and retrieval of classes of information, such as ``find all photos containing trees'' or ``all places where there is laughter.'' * Search on compressed representations, and new representations that facilitate efficient semantic or perceptual searching. * Intelligent searching through huge amounts of text or data, e.g. for DNA matching or drug design. * Automatic annotation to generate descriptions of data, especially based on combinations of visual, acoustic, and motion (temporal) features. * Recognition of video content invariant to viewing conditions, e.g., ``Find all other shots of this scene.'' * Computational measures of perceptual similarity: especially texture, shape, color, that have been evaluated on a large set of data, e.g., ``computer, are there any other drum patterns that sound like this?'' or ``find fabrics which look most like this one.'' * Segmentation of video/soundtrack/image as applied to database search and retrieval. * Automatic extraction of video keyframes, or analogous summarizing information in non-visual media. All papers will be reviewed by the guidelines of the transactions. Please submit four copies of your paper to: Prof. Rosalind W.
