Abstract
HEVC is the new video coding standard developed in a joint effort (JCT-VC) by ISO MPEG and ITU-T VCEG. As other state-of-the-art block-based inter-prediction codec, it is very sensitive to illumination variations in-between frames. To cope with this limitation, the weighted prediction (WP) tool has been proposed. A comparison of the performance of WP in HEVC and MPEG-4 AVC/H.264 is carried out. The efficiency of WP is very dependent on the quality of the estimated WP parameters. The different stages of state-of-art WP parameters estimators are discussed and a new algorithm is proposed. It is based on histogram matching with global motion compensation. Several options are evaluated and comparison is made with other existing methods.
