Efficient Motion Vector Interpolation for Error Concealment of H.264/AVC

Abstract

In video communications the compressed video stream is very likely to be corrupted by channel errors. In order to combat these channel errors, many methods have been proposed. In this paper, a new method for motion vectors (MVs) interpolation with the help of MV extrapolation (MVE), is presented to conceal the corrupted frame of H.264/AVC. In our proposed method, the MVs of lost blocks can be obtained after interpolation with the extrapolated MVs. Experimental results show that this method is able to provide better performance than existing algorithms in terms of PSNR.
