摘要
提出一种面向立体视频的比特分配与码率控制算法以提高立体视频的编码效率和码流可靠性。算法对传统二次率失真模型进行了改进,并结合人眼的立体视觉特性,提出了新的码率控制策略。实验结果显示,改进后的率失真新模型具有更高的准确性,提出的算法能根据编码参数进行有效的比特分配和码率控制。
A new bit-allocation and rate-control algorithm for stereo video coding was proposed to improve its coding efficiency and stream reliability. The conventional quadric rate-distortion model was improved and a new one was introduced by incorporating the human visual system （HVS） characteristics. Experimental results show that the improved new rate-distortion model is more precise than the conventional one and the proposed new algorithm can efficiently implement bit allocation and rate control according to coding parameters.
