Abstract :
We propose a motion-compensated error concealment method for HEVC and implement the method in reference software HM. The motion vector from the co-located block will be refined for motion compensation. Based on the reliability of these MVs, blocks will be merged and assigned with new MVs. The experimental results show both a substantial PSNR gain as well as an improvement in visual quality.
