Comparison of motion vector coding techniques

This paper deals with the comparison in different motion vector coding methods suitable for motion compensated image communication systems. Both waveform and description coding techniques are presented and applied to a dense motion field. Only lossless compression is considered, and a reduction factor between 3:1 and 9:1 of the raw bit rate of the motion vectors can be reached. Although some of these techniques have already been used for the coding of motion information it would be greatly interesting to compare them in the same conditions, with intent to apply them to professional motion compensated applications as opposed to the particular case of motion compensated picture coding.
