Paper Abstract

The H.264/AVC standard utilizes temporal prediction tools to obtain a good coding performance by reducing temporal redundancy between frames. However, because H.264/AVC does not efficiently encode video sequences that have a local illumination change, the coding performance of H.264/AVC is dropped when the local illumination changes occur in video. We propose an adaptive motion compensation method using neighboring pixels and motion vector refinement to efficiently encode the local illumination changes. By using the proposed method, we achieve a bit savings up to 6.86% with peak signal-to-noise-ratio gain compared to H.264/AVC.
