Multiview Video Coding Scheme Based on Disparity Estimation Algorithm

多视点视频编码是立体视频的关键技术,视差估计是目前多视点视频编码中常用的方法之一。探讨了多视点视频编码中的视差估计算法原理,对当前应用视差估计算法的几种典型预测结构进行了深入分析,提出一种结合分级B图与视点相关性的多视点编码方案,该方案在H.264/AVC的编码模型JM下实现。实验表明,该方案在兼顾随机访问性能的同时,实现了较高的编码效率,尤其适合视点间相关性较高的运动图像序列。

Multiview video coding is a key technology of stereo video,and disparity estimation is the most popular algorithm of current multiview video coding schemes. The theory of disparity estimation algorithm is first investigated, and several typical coding techniques are analyzed in detail. Then a novel multiview coding scheme is proposed which is based on hierarchical B pictures and correlation property of viewpoints. Experimental results show that the proposed scheme is efficient.
