摘要
本文介绍了立体视频编码方法。并对其关键技术-视差补偿预测技术进行深入研究。本文所提出的基于视差分割的视差补偿预测算法是建立在可变尺寸块匹配算法的基础上,充分利用视差信息实现对目标图像帧的有效分割,并采用相适应的视差向量编码方案。与传统算法相比,在相同预测精度下,明显降低了视差信息编码开销。
The paper introduces the method of stereo video coding, and researches disparity compensation prediction technique. The paper presents the disparity-based segmentation algorithm, which is based on variable size block matching. The algorithm can fully utilize the disparity information of a frame to segment it efficiently, and adopts a corresponding scheme of encoding disparity vectors. The algorithm can evidently reduce the coding overhead for disparity information with the same prediction precision.
