针对立体视频序列的时间空间冗余和交叉冗余,提出一种快速编码算法.应用立体-运动约束模型在视差域和运动域进行联合迭代搜索,根据每次迭代后的模型误差设置自适应修正窗口来保证预测矢量精度,视差矢量和运动矢量可以快速同步获得.实验结果表明,该算法在保证高率失真性能的同时,可以大幅度降低编码复杂度.
For the purpose of exploiting the intra-view and inter-view dependencies of stereo video,a fast motion and disparity estimation is proposed in this paper.The key idea is to perform iterative search in both the motion and disparity fields based on the stereo-motion consistency constraint model,and adaptively refine the window size according to the model errors after each iteration to ensure the vector accuracy.In this way,both the motion and disparity vectors can be obtained quickly.The experimental results demonstrate that the proposed algorithm can reduce coding time dramatically at the cost of a negligible quality decreasing.
