METHOD OF PARTIAL BLOCK MATCHING FOR FAST MOTION ESTIMATION

摘要

PURPOSE: A method for matching partial block, capable of achieving fast motion estimation is provided to maintain not only reducing the complexity but also restoring the restored image of picture quality the same. CONSTITUTION: A histogram is obtained from each pixel values of current macro block(S410). A pixel which will be participating in a partial block matching is selected(S420). The selected pixel which will participate in a partial block matching is matched as pixel-to-pixel in the current macro block and a candidate macro block(S430). The pixel which will participate in the partial block matching is adaptively determined according to the histogram characteristic of pixel of the current macro block.
