Abstract :
The coding efficiency improvement of stereoscopic video system is a hot research topic in the 3D video coding areas. To better exploit the redundancy between the two channels of stereoscopic video, a stereoscopic video coding scheme for Audio Video Coding Standard (AVS) is proposed in the paper. The superior coding performance of the proposed scheme benefits from an enhanced block prediction algorithm, which includes an improvement of AVS direct mode and motion vector prediction, as well as adaptively combining the prediction results of motion compensation and disparity compensation. The experimental results demonstrate that the proposed scheme and algorithm greatly outperforms the reference software of AVS.
