Abstract

Wavelet transform is a popular tool for image and video coding. It has several advantages in multiresolution analysis and subband decomposition of images. Motion estimation and motion compensation methods are widely used to reduce temporal redundancy in video sequences. Although there have been several attempts to compensate for the motion in the wavelet domain, their performances are limited due to the shift-variant problem. In this paper, we propose a new motion compensation method in the wavelet domain to overcome the shift-variant problem. Experimental results show that the proposed method outperforms the previous motion compensation methods in the wavelet domain as well as the full search algorithm in the spatial domain.
