A New Scheme Of Layered Coding Of Stereoscopic Video
A new scheme of layered coding of stereoscopic video based on the correlation of motion vector fields (MV fields) is proposed in this paper, in which the bit streams robustness is improved to error channel and the coding efficiency is not reduced evidently. In our proposed scheme, the stereoscopic video is classified into one base layer and two enhancement layers. First, left-view video is encoded as Base Layer to ensure the basic quality of two-dimensional video. Then, the disparity vectors(DVs) of right-view video are encoded as Enhancement Layer 1.To lower bit rates further and reduce the network load, the strong correlation of the motion vectors(MVs) for two views video sequence are tested. Based on the correlation of MVs between views, the MVs of right-view are transmitted as Enhancement Layer 2 only if the correlation between left and right view is less than some threshold. Experimental results are demonstrated to testify the efficiency of our proposed scheme.
