Abstract
Methods and systems for encoding a video signal representative of a plurality of image frames which include a starting frame and at least one subsequent frame, include a step of identifying at least one object in the image frames. A plurality of feature points of the at least one object are located in the image frames. A mathematical transformation which maps locations of the feature points in the starting frame to locations in each subsequent frame is determined. The bit plane representation of the starting frame and the mathematical transformation are encoded and multiplexed to form a bit stream. Methods and systems for decoding the bit stream perform a step of transforming the bit plane representation of the starting frame in accordance with the mathematical transformation to form a bit plane representation for each subsequent frame.
