Paper Abstract

In video coding it is clearly worthwhile to have a more realistic motion field than what can be obtained by the classical mean absolute difference (MAD) full search method. Applications can be found in very low bitrate coding where the amount of bits to code the motion field is important compared to the total bitrate, in codecs which want to exploit some features of the human visual system (classification for optimal bit allocation, use of motion masking...) or in object based coding where the motion estimation algorithm interacts with the segmentation procedure. Our research started from the well known MAD full search procedure and wanted to obtain reasonable results without adding too much complexity. The improvement is performed inside the algorithm without any need for post processing. After a more thorough description of these improvements, some results will be compared and applications indicated.
