Abstract: |
A coding structure for group of blocks is prepared as defining M pixel X N pixel to be group of blocks containing original group of blocks and derived group of blocks, setting original group of blocks to be continuous group of blocks with M pixel ¡ÁN pixel, setting up derived group of blocks by carrying out vertical 1/2 sampling on original group of blocks, obtaining M pixel ¡Á N pixel group of blocks after rearrangement .The adaptive-sectional prediction coding method based on said structure for group of blocks is also disclosed . |
