Error concealment algorithm using inter-view correlation for multi-view video

Abstract

Abstract This paper proposes an error concealment algorithm for whole frame loss for multi-view video decoding. In our proposal, the relationship between motion vectors and disparity vectors is exploited first. Based on the parallelogram-like motion relationship, the motion vectors of error frames can be indirectly derived by projecting the disparity vectors from the counterpart view. In addition, to further improve the concealing results, a joint sum of the absolute difference (SAD) minimization approach is also proposed to find the block for the purpose of concealing the current error block by jointly considering motion vectors and disparity vectors. Experimental results show that our proposed algorithm provides better video quality than previous work and reduces error propagation.
