ADAPTIVE PREDICT BASED ON FADING COMPENSATION FOR LIFTING-BAED MOTION COMPENSATED TEMPORAL FILTERING

By Li Song, Hongkai Xiong, Jizhen Xu, Feng Wu and Hui Su

Abstract

Lifting implementation of the discrete wavelet transform applied along motion trajectories has recently gained a lot of attention in video community as strong candidates to incoming scalable video coders. In this paper, we generalize the coding scheme for classical lifting-based motion compensation temporal filtering and permit codec to adaptively choose between original reference frames and new fading-compensated reference frames to predict residuals while maintaining the invertibility of the inter-frame transform. Experimental results show that the proposed algorithm not only significantly improves subjective visual quality of the temporal low-pass frames but also have the 0.15~0.3db gain in PSNR performance compared with the normal (5, 3) lifting schemes. � 1
