Patent ID: 7050503

Claim:
An encoding system, wherein an encoder encodes uncompressed video data to form compressed video data and a decoder decodes the compressed video data to form at least an approximation of the uncompressed video data, and wherein the video data comprises a sequence of a plurality of image frames comprising key frames and nonkey frames, the encoding system comprising: an encoder comprising: a) a segmenter that generates a segmentation of a reference frame, wherein a reference frame is a frame having content that is used in encoding a nonkey frame and wherein the segmentation is an assignment of some or all of the pixels of the reference frame to segments based on at least one of pixel color values of the pixels and location of the pixels in the reference frame; b) a kinetic information generator that generates kinetic information that relates regions of a nonkey frame to segments of the reference frame as indicated by the segmentation generated by the segmenter; c) a residue coder that codes for differences between a frame representing differences between content of the nonkey frame and a frame resulting from an application of the kinetic information and segmentation of the reference frame, wherein the residue is coded as coefficients of basis functions; and d) a compressed video data outputter that outputs compressed video data including at least compressed key frames, the kinetic information and residue data; and a decoder that regenerates a nonkey frame from the compressed video data using kinetic information about the nonkey frame from the compressed video data, segmentation of the reference frame and residue data about the nonkey frame.
