Depth-assisted error concealment for intra frame slices in 3D video

We propose a depth-assisted error concealment method for slice loss in intra frames of 2D+depth video sequence. Intra frames in the 2D view sequence are offset from intra frames in the depth sequence to guarantee the corresponding frame in the other sequence is not also intra mode. Then for a slice loss in an intra frame in the 2D view sequence, the motion information is extracted from the depth sequence to conceal the slice loss using boundary matching. Experimental results show that the proposed method provides improved performance over existing methods both for PSNR results and computational complexity at the decoder.
