    A content-based 3D neuroradiologic image retrieval system is being developed at the Robotics Institute of CMU. The special characteristics of this system include: directly dealing with multimodal 3D images (MR/CT); image similarity based on anatomical structures of the human brain; and combining both visual and collateral information for indexing and retrieval. A testbed has been implemented for u... View full abstract»

    Current methods for shape-based image retrieval are restricted to images containing 2-D objects. We propose a novel approach to querying images containing 3-D objects, based on a view-based encoding of a finite domain of 3-D parts used to model the 3-D objects appearing in images. To build a query, the user manually identifies the salient parts of the object in a query image. The extracted views o... View full abstract»

    Image databases are now a subject of increasing attention in multimedia, for archiving and retrieval of images in the fields of art, history, medicine and industry, among others. From the psychological point of view, color perception is related to several factors including color features (brightness, chromaticity and saturation), surrounding colors, color spatial organization, observer memory/know...

    A new class of algorithms based on triangle inequality has been proposed for use in content-based image retrieval. These algorithms rely on comparing a set of key images to the database images, and storing the computed distances. Query images are later compared to the keys, and the triangle inequality is used to speedily compute lower bounds on the distance from the query to each of the database i... View full abstract»

    We present our techniques and results on automatic analysis of tennis video to facilitate content-based retrieval. Our approach is based on the generation of an image model for the tennis court-lines. We derive this model by using the knowledge about dimensions and connectivity (form) of a tennis court and typical camera geometry used when capturing a tennis video. We use this model to develop: a ... View full abstract»

    We show how high-level scene properties can be inferred from classification of low-level image features, specifically for the indoor-outdoor scene retrieval problem. We systematically studied the features of: histograms in the Ohta color space; multiresolution, simultaneous autoregressive model parameters; and coefficients of a shift-invariant DCT. We demonstrate that performance is improved by co... View full abstract»

    Digital video is rapidly becoming important for education, entertainment and a host of multimedia applications. With the size of the video collections growing to thousands of hours, technology is needed to effectively browse segments in a short time without losing the content of the video. We propose a method to extract the significant audio and video information and create a skim video which repr... View full abstract»

    Video information processing and retrieval is a key challenge for future multimedia technologies and applications. Commercial videos encode several planes of expression through a rich and dense use of colors, editing effects, viewpoints and rhythms, which are exploited together to attract potential purchasers. In this paper, previous research in the marketing and semiotics fields is translated int... View full abstract»

    In content-based access of image databases, there is a need for a shape formalism that allows a precise description and recognition of a wider class of shape variations that evoke the same overall perceptual similarity in appearance. Such a description not only allows images of a database to be organized into shape categories for efficient indexing, but also makes a wider class of shape-similarity... View full abstract»

    Video OCR is a technique that can greatly help to locate topics of interest in a large digital news video archive via the automatic extraction and reading of captions and annotations. News captions generally provide vital search information about the video being presented, the names of people and places or descriptions of objects. In this paper, two difficult problems of character recognition for ... View full abstract»
