提出了一种基于复杂度的率失真联合优化算法, 该算法在H.264/AVC视频编码标准中率失真优化算法的基础上考虑了视频编码算法复杂度因素, 以求达到对视频编码复杂度和率失真性能联合优化的效果, 并通过引入复杂度控制因子对编码复杂度进行控制调节。实验结果表明, 该算法可以在保证率失真性能降低很小的情况下降低视频编码的复杂度, 在率失真和复杂度之间取得了很好的均衡效果。

A complexity based joint rate-distortion optimization algorithm is presented, which taking the complexity factor of video coding into account based on the rate-distortion optimization algorithm in H.264/AVC video coding standard.Thus a better effect can be obtained on the tradeoff between rate-distortion performance and video coding complexity.Besides that, this framework introduces a complexity control factor to control the extent of complexity.Tests show that the proposed framework can reduce the complexity without much sacrifice in coding efficiency.
