Abstract
The discrete wavelet transform (DWT) has several advantages in multi-resolution analysis and subband decomposition, which has been successfully used in image compression. In this paper, we will extend the usage of DWT to video compression and focus on motion estimation (ME) and motion compensation (MC) in wavelet domain. The ME used in this paper is Low-Band-Shift Motion Estimation (LBSME) [1] and a novel MC in wavelet domain is proposed. With this novel method, ME/MC in wavelet domain now is comparable with ME/MC in spatial domain and the performance is superior to other ME/MC methods in wavelet domain.
