Abstract
A method for encoding input contour image including a current contour based on a previous contour, the contour encoded previously, is provided. In this method a predicted contour is generated from motion estimating and compensating the previous contour based on the current contour. By indexing the contour pixels on the predicted contour and encoding the indices of the end-points of matched segments, parts where the predicted and the current contours overlap, encoded major vertex information is provided. Unmatched segments, parts on the current contour which are not included on any of the matching segments, are polygonal approximated to find minor vertices and relative location of the minor vertices are encoded to provide encoded minor vertex information. When encoding the minor vertices, modes for encoding the number of minor vertices are selected to minimize the number of bits for encoding the number of minor vertices. By multiplexing the encoded major vertex information and the encoded minor vertex information, the present method supplies encoded contour information.
