ABSTRACT:
A method encodes a contour image of an object expressed in a video signal. First, a centroid for the contour of the object is detected by averaging pixel positions on the contour. A set of primary vertices on the contour are determined based on the centroid. Subsequently, a set of secondary vertices on the contour are determined based on the set of primary vertices. The set of primary vertices, the set of secondary vertices and the centroid are encoded to provide a digitally coded contour signal.
