Temporal Error Concealment Using Recursive Boundary Matching Method

In this paper, we proposed a temporal error concealment (EC) using recursive boundary matching method. The proposed recursive boundary matching method improves the spatial correlation of the macroblocks (MBs) by reusing the pixels of the concealed MB and control weighting factor of the concealed MB recursively. And proposed algorithm has both forward concealment and backward concealment to prevent error propagation. Experimental results show that proposed algorithm gives better results than the conventional algorithms from a subjective and an objective viewpoint.
