针对H.264的码率控制算法的不足,利用视频中各图像的运动活动性实现了帧级比特分配,实现结果与JVT-G012提案相比,本文方法在精确控制码率的同时,图像的视觉质量也得到了提高。
Aiming at the shortage of H.264 rate control algorithm, the frame-level bit allocation is realized by using the motion activity of each image in the video. Compared with the proposed JVT-G012 scheme, this method can control bit- Visual quality has also been improved.
