Summary:
In this paper, we propose a new error concealment algorithm that can effectively reconstruct the lost frame caused by transmission errors in the wireless environment. The proposed algorithm employs the bilateral motion estimation scheme where the received motion vectors (MVs) in the neighboring frames are weighted and utilized to construct the MV field for the concealed frame. Experimental results show that the proposed algorithm outperforms other techniques in term of both peak signal-to-noise ratio (PSNR) performance and subjective visual quality.
