A hybrid error concealment for intra frame in stereoscopic video

A hybrid error concealment method is proposed for slice losses in intra frames of view plus depth stereoscopic video. GOPs are offset between the view and depth sequences to guarantee the frame in the other sequence corresponding to the intra-frame is not intra mode. For lost regions near the edges in the frame, the MV is recovered from the corresponding depth frame. For other regions where the corresponding MVs in the depth frame are not available, the MV is recovered from co-located MB and its neighboring MBs in previous frame. If the boundary match distortion of these MV candidates is higher than a threshold, motion estimation (ME) will be re-executed for the neighboring MBs of the lost region. Experimental results show that the proposed method is more effective than existing methods.
