摘要
针对在小波域内作运动估计的局限,提出了一种冗余小波域内的运动估计,通过块匹配来搜索精确的运动矢量和相位矢量,得到更小能量的残差帧,有效地提高了编码器的效率。
To overcome the limitations of the motion estimation in the wavelet domain, we propose a kind of motion estimation in the redundant wavelet domain, which search the actual motion vector and phase vector through the block matching algorithm to get the residual frame of less energy. This motion estimation in the redundant wavelet domain can result into the improvement of coding efficiency.
