ABSTRACT:
A method and an apparatus for predictively coding a contour of a video signal. An error between the current contour and the previous contour is obtained through the comparison therebetween. If the obtained error is greater than or equal to a predetermined reference value, the current contour is coded. However, in the case where the obtained error is smaller than the predetermined reference value, only a signal indicative of the reconstruction of the current contour using the previous contour is transmitted to a decoder. Therefore, the transmission of unnecessary information is prevented to enhance the compression coding efficiency.
