ABSTRACT:
Video data is compressed with nonkey frames encoded with reference to segmentation of reference frames, where the encoded video data includes kinetic information relating segments of a reference frame to pixels of a nonkey frame and the kinetic information includes translations of segments and at least one of a z-order, a deformation and a lighting change. The segmentation performed during encoding can be included in whole or part in the compressed video data. If used, z-ordering could be relative or absolute, based on changes of occlusion of segments by other segments between the frames, based on content of other frames or based on z-order indications in the video data being compressed. Other kinetic information might include segment changes between frames such as rotation, dilation, affine transformations, nonlinear transformations defined by a set of deformation parameters, linear lighting offsets in one, two or three color planes, and/or residue information.
