ABSTRACT:
Introducing a further prediction stage, namely a prediction of the motion vectors or the prediction error of the first prediction stage, does indeed at first increase the encoding or compression effort and, correspondingly, also the decoding or decompression effort, but the prediction proposed here leads to a significant improvement of the compression gain in relation to the effort in most graphics model sequences due to the uniformity of the motion.
