Abstract

Error Concealment (EC) algorithms have provided a very useful tool for concealing the errors in digital video streams. The importance of EC methods arises specially in broadcasting and multicasting communications where retransmission of corrupted video sequence is not possible. In this paper, a Motion Vector (MV) space is proposed around each erroneous macroblock (MB) and thus the candidate MV can be refined using a Gaussian window effectively. Gaussian window application in this scenario is analyzed in detail. Finally, simulation results proves the superiority of the proposed method to the conventional approaches.
