The proposed algorithm based on mathematical models of the motion compensated prediction errors. Unlike conventional quarter-pixel accuracy hierarchical motion estimation algorithm, proposed algorithm can avoid fractional-pixel interpolation and subsequent fractional-pixel search after integer-pixel accuracy motion estimation.
该算法基于运动补偿预测误差模型,与传统的1/4像素的分层运动估计算法不同,仅通过一步计算就能直接得到1/4像素精度的运动矢量,而且完全避免了运算量很大的分数像素内插运算和整像素搜索完成后的分数像素搜索。
