Abstract: Wyner-Ziv video coding is a typical distributed video coding.For generating more accurate side information,this paper presents a way of bidirectional prediction of side information based on motion estimation,constructs a motion compensation framework and improves its algorithm.Matlab simulation results illustrate that the rate-distortion performances of the proposed method work well,characterized by 0.1~9.0 dB higher than H.264 Intra coding and 0.01~0.90 dB higher than the discover software based on Turbo code.

摘要: Wyner-Ziv视频编码是一种典型的分布式视频编码。为了产生较为精确的边信息,提出了一种基于运动估计双向预测边信息的方法,构造了运动补偿内插框架以及改进了算法。Matlab仿真结果表明,改进方法的率失真性能比H.264帧内编码高出0.1~9.0 dB,比基于Turbo码的Discover软件高出0.01~0.90 dB。
