摘要：To improve the performance of rate control algorithm for H.264/AVC and keep a good quality for video, a new rate control algorithm is proposed based on the just noticeable distortion (JND). Firstly, the motion characteristics of inter-frames were used to measure the frame complexity as to allocate the target bits rationally in frame level. Secondly, just noticeable distortion for measuring visual sensitivity of macro-block was introduced, and the bits allocation of macro-block is based on the JND value. The experimental results show that the proposed algorithm can control the bit-rate more accurately and improve the subjective quality of the visual sensitive areas without any rate-distortion performance decline compared with JVT-G012 algorithm.
