| Abstract: | A new efficient method, based on a differential PCM technique, for encoding the leaves of a pruned quadtree is presented. Solutions to the problems of causality maintenance during tree scanning-encoding and of fast neighbour finding are described. The result is a constant wordlength code with a remarkable rate-distortion performance |
