<p>A method for scalably inter-contour coding a video signal including a previous and a current frames, wherein each of the previous and the current frames contains a contor, first generates a predicted contour by motion estimating and compensating a previous base layer, widens the predicted contour by a predetermined threshold Dmax(j), generates (j)th primary and secondary vertices, and reconstructs a current base layer, j being 0. Thereafter, the method widens the predicted contour by the predetermined threshold Dmax(j+1), generates (j+1)st primary and secondary vertices, and updates the (j)th primary and secondary vertices. Then, the (j)th primary and secondary vertices are encoded, and encoded primary and secondary vertex information is formatted in a predetermined way. Finally, the value of j is increased by 1, and the process from widening the predicted contour by Dmax(j+1) to formatting the encoded primary and secondary vertex infromation are repeated until j becomes N, N being a positive integer. <IMAGE></p> |
