Abstract
In a digital video motion estimation compression and decompression system, pixel block-matching is accomplished by comparing pixels in target block regions of high gradients of luminance or hue. A few pixels from low-gradient regions are also preferably used. A mask defining these pixel locations in the target block is created, and the block comparisons with other blocks are based only on the relative values associated with the pixels in these locations. Major computational time savings are accomplished with negligible degradation of image quality.
