Weighted prediction methods for improved motion compensation

Weighted prediction in the H.264/MPEG-4 AVC video coding standard is a coding tool used primarily for improving coding efficiency during illumination changes, such as fading transitions. In this paper, we extend the usage of weighted prediction within the context of motion compensation in H.264, to further improve coding efficiency even for scenes with constant illumination characteristics. This is done by better exploiting coding tools already available in H.264 such as reference list reordering and multiple reference prediction.
