Auto-regressive model based error concealment scheme for stereoscopic video coding

Stereoscopic video is an important manner for 3-D video applications, and robust stereoscopic video transmission has posed a technical challenge for stereoscopic video coding. In this paper, an auto-regressive (AR) model based error concealment scheme is proposed for stereoscopic video coding to address the challenging problem. The proposed error concealment scheme includes a temporal AR model for independent view, and a temporal-interview AR model for inter-view predicted view. First, appropriate motions and disparities for lost blocks are derived. Then, the proposed AR model coefficients are computed according to the spatial neighboring pixels and their temporal-correlated and interview-correlated pixels indicated by the selected prediction directions. Finally, applying the AR model, each pixel of the lost block is interpolated as a weighted summation of pixels in the reference frame along the selected prediction directions. Simulation results show that the performance of the propos...
