<p>A contour encoding method codes a current contour in a current frame based on a predicted current contour which is selected among previously reconstructed contours within a previous frame. Once the predicted current contour which is most similar to the current contour is detected, the method matches the predicted current contour with the current contour and widens the predicted current contour to thereby detect non-matching sections and matching sections between the current contour and the predicted current contour. Subsequently, the portions of the current contour which correspond to the non-matching sections are encoded through a polygonal approximation technique. The result of the approximation technique and information for the predicted current contour are multiplexed and then transmitted as encoded contour data. <IMAGE></p> |
