摘要:Various methods have been proposed for motion compensation for moving pictures. Each method has advantages and disadvantages regarding performance, but they have not necessarily been discussed under fair conditions. In this paper, we investigate four representative motion compensation methods : block matching, motion compensation using affine transformation, warping prediction, and global motion compensation. We evaluated the performance of these methods by applying MPEG-2 for the input of common natural video sequences. We show that motion compensation methods which have been proposed to improve the performance are not superior to the conventional block matching when they are used in conjunction with MPEG-2.
