Abstract :
In the video coding standard H.264/AVC, various coding tools have been proposed to improve the efficiency of motion compensation (MC). In this paper, the overlapped block motion estimation and compensation (OBME/MC) is applied to the framework of H.264/AVC encoder to further increase the coding performance. Our main contribution is to adapt the overlapped weighting factors to the coding mode of neighboring blocks, thus allowing efficient integration of OBMC with variable block size motion compensation in H.264. The result shows that integration of OBMC will provide PSNR gain up to 0.21dB when the encoding bit-rate is high
