Shen Lan-sun · Dianzi xuebao · 2004
In this paper, we proposed a fast block matching motion estimation algorithm based on temporal and spatial motion correlation among adjacent blocks for H. 264/AVC coding standard. This algorithm well exploits the correlation between video sequence motion activity and macro-block coding pattern and motion vector statistic characteristics, so it significantly reduces the search complexity of motion estimation. Experimental results show that the algorithm provides PSNR 0.06 dB gain compared to DS and is closer to that of FS with speedup ratios of 77.96 % and 32.19 % on average compared to FS and DS respectively.
