摘要： Meta data about content is converted into characteristic values. Each characteristic value is associated with one or more content segments of content. The content can be audio, video, or other data or combinations of data. Importance levels for content segments are determined from content scores. Content scores are generally an indication of how one person would rate a particular characteristic value. The content scores may be estimated by using previously determined scores of similar content segments. The similarity is preferably determined by a particular metric. A user may also supply his or her own content scores for content segments. The user profile content scores can be combined with the determined content scores or completely supplant these scores. Based on the importance levels for content scores for content segments, content segments may be packaged into a content digest that a user may view.

摘要： The invention provides a method for classifying the motion of an object such as a human being in a moving picture. A template is prepared in advance, which includes the Gabor wavelet expansion coefficients of an object image in a plurality of frames of a video image sequence representing each of a plurality of different reference motions of an object in a moving picture. Then, processing is performed to obtain the Gabor wavelet expansion coefficients of an object image in a plurality of frames of a video image sequence representing an unknown motion of the object. Matching factors are calculated based on the expansion coefficients for the unknown motion and the expansion coefficients for the reference motions in the template, and finally the unknown motion is classified based on the matching factors.

摘要： The invention provide methods and apparatus for effectively identifying the occlusion of objects, such as persons, having a high degree of freedom. In an example embodiment, after initialization, an image is input, and an image region is extracted from image data. The distance is employed that is obtained when the shape of a two-dimensional histogram in the color space is transformed into the feature space. A graph is formed by using, the regions between the frames. A confidence factor is provided and image features are provided as weights to the edges that connect the nodes. Processing is performed, and the confidence factor is examined. A connection judged less possible to be a path is removed. When there is only one available connection for the occlusion point, this connection is selected.
