基于方向提升小波变换的多描述视频编码
Multiple Description Video Coding Based on Directional Lifting Wavelet Transform
摘要
Abstract
A multiple description scalable video coding based on directional lifting wavelet transform is proposed, it can enhance the error-resilient and network-adaptive ability of video coding. It divides each frame into two subframes to form two subsequences by using quincunx down-sampling, each subsequence is coded by a scalable 3D wavelet video coder to form one description. To improve coding efficiencies of the subframes, directional lifting wavelet transform is used to perform spatial decomposition. A five mode directional lifting is introduced to improve coding efficiency. Experimental results prove the validity of the proposed algorithm.关键词
