Abstract:
1. A computer apparatus for the purpose of generating an encoded form of video signal data from a plurality of video frames, comprising: a means of identifying corresponding elements of an object between two or more frames in a sequence of video frames of subject video signal data; a means of modeling such correspondences to generate contour models that are used to segment the object from non-object background in the video frame sequence, where the contour models are created by determining contour vertex positions in accumulated error regions of image intensities that are coincident with the object; a means of segmenting and resampling pel data in said video frames associated with said object, said segmenting and resampling means utilizing said contour models; a means of restoring spatial positions of the re-sampled pel data, said restoring means utilizing the contour models; said object being one or more objects; and said re-sampled pel data being an intermediate form of the subject video signal data.
