A Novel Wavelet-Domain Motion Estimation Algorithm

摘要

摘要: 离散小波变换中的位移可变性严重影响了小波域运动估计的精度。为了克服位移可变性，该文采用了一种新的双通道高通滤波方法，提出了一种新型小波域运动估计算法。仿真实验结果表明这种新算法比现有其他同类算法具有更好的性能和更低的计算复杂度。

Abstract: The shift-variant property of discrete wavelet transform makes wavelet-domain motion estimation inaccurate. In order to overcome the shift-variant property, a 2-channel high-pass filtering method and a wavelet-domain motion estimation algorithm are presented. The experiment results demonstrate validity of the new method, and indicate the new wavelet-domain motion estimation has comparable performance and low calculated complexity. Therefore, this is likely appealing for the wavelet video coding applications.
