MOTION ESTIMATION AND COMPENSATION PROCESS AND DEVICE


In the motion estimation and compensation process for video frames, blocks O of pixels are considered. A number k of bit planes in a block O in a video frame F are compared with blocks OR in reference frames (FR). The best matching block (ORM) is determined in the reference frames (FR). Subsequently, a weight value (WX IJ) is calculated for the best matching block (ORM) based on the ratio of valid pixels therein. The residual pixel values (VX IJ) extracted from the best matching block (ORM) and corresponding weight values (WX IJ) are stored in a pixel prediction array (120). The pixel array is used for motion compensation of at least the luminance component of valid pixels. Invalid pixels are reconstructed from surrounding pixel values.
