Temporal error concealment based on grey polynomial interpolation

As networking technologies advance, video transmitted over internet is very common nowadays. However, error-prone channel generally causes packet loss and thus affects the visual quality of reconstructed frames significantly. One popular approach to deal with the problem is error concealment since no burden on bandwidth is loaded. In this paper, an error concealment approach based on grey polynomial interpolation is proposed. The approach utilizes two available frames, before and after the error frame, to conceal the errors due to packet loss. Simulation results through H.264 JM12 indicate that the proposed approach has better performance than error concealment schemes in H.264 and boundary matching algorithm, both in PSNR and visual quality.
