Weighted prediction methods for improved motion compensation
Image Processing(2009)
摘要
Weighted prediction in the H.264/MPEG-4 AVC video coding standard is a conding tool used primarily for improving coding efficiency during illumination changes, such as fading transition. 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.
