Patent ID: 7158680

Claim:
A digital processor apparatus for generating an encoded form of video signal data from a plurality of video frames, comprising: means for detecting an object in a video frame sequence; means for tracking said object through two or more frames of the video frame sequence; means for identifying corresponding elements of said object between two or more video frames; modeling means for modeling such correspondences and generating a correspondence model; means for resampling pel data corresponding to the object in said video frames, said resampling means utilizing said correspondence model; segmentation means for segmenting said pel data corresponding to said object from other pel data in said video frame sequence, resulting in segmented object pel data; decomposition means for decomposing said segmented object pel data, said decomposition means applying Principal Component Analysis, and said segmentation means including a temporal integration, and said modeling means (i) analyzing the correspondence model using a robust sampling consensus for the solution of an affine motion model, and (ii) analyzing the corresponding elements using a sampling population based on finite differences generated from block-based motion estimation between two or more video frames in said sequence.
