An Efficient Multi-Hypothesis Temporal Error Concealment Method for H.264

Abstract:

An efficient multi-hypothesis Temporal Error Concealment (TEC) method is proposed in this paper. Two compensated MarcoBlocks (MB) are obtained by two basic TEC approaches. Process of noise Motion Vector (MV) removal is introduced to get compensated MB more accurately. The lost MB is then concealed by weighted combination of the two MBs in which the weight is adjusted adaptively by calculating standard deviation of candidate MV set. Experimental results demonstrate that the proposed method can overcome shortcoming of fixed weight and provide better performance.
