Abstract
Regarding motion compensation for moving pictures, various methods have been proposed so far. In these proposals, merits and demerits regarding performance are discussed for each method, but they are not necessarily discussed under fare conditions. In this paper, we investigate these 4 methods as representative motion compensation methods, "block matching", "motion compensation using affine transformation, ""warping prediction"and"global motion compensation". Then we evaluated the performance of those methods, applying the typical coding method, MPEG-2,for the input of common test sequences. As a result, 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.
