摘要： 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.

摘要： The present invention provides methods for extracting an image region segment from a video image, a system for extracting an image region segment, a program for extracting an image region segment, a method for distributing an extracted video image, and a method for generating content. Motion compensation data is calculated using sequential video images captured by a video camera, and the sequential video images are employed to prepare an estimation of the video camera operation. Based on the estimated camera operation, the center position (xc, yc) of an area that is aimed at in a video image is estimated under predetermined conditions (rules), an image feature is designated in the vicinity of the center position of the target area, and an image segment is specified that includes this image feature.

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： Polyhedral data is compared with limited information while keeping accuracy. A comparison of two polyhedrons is accomplished as follows. (1) A squared-sum of the difference of primary moment functions and a squared-sum of the difference of secondary moment functions are separately sought at sample points of polyhedron Ma, Mb, normalize them and compute the sum of both, or seek sum functions of the primary moment functions and the secondary moment functions to compute the squared-sum of the difference of the sum functions, the primary moment function all the sample points of polyhedral data that occupy central symmetry directions are blended in the same sign, which is the different sign in the case of the secondary moment function, the functions having variables representing points on a surface of a sphere of which center is the center of gravity of the polyhedron and a value which is an axial moment value, the axis defined as a line through the points and the center, and (2) in the case that the value of the sum is a certain threshold or less, it is determined that the polyhedrons are similar in shape.
