摘要
本文针对隔行扫描图像,提出了一种基于“场子宏块匹配法”和“4:1抽样子块匹配法”的快速位移估值算法,将总的运算量缩减到穷举搜索法的1/32数量级,而重建图像的主观质量下降甚少。
New motion estimation algorithms for interlaced pictures coding are proposed in this paper, named with the Field Submacroblock Matching Method and the 4:1 Subsampled Block Matching Method. The computation complexity of the proposed algorithm has reduced to 1/32 of that using the full search method,with little descent in the reconstructed pictures.
