Title
A novel rate control algorithm for H.264/AVC based on human visual system
Abstract
To improve performance of rate control algorithm for H.264/AVC, and keep a better control accuracy of the output of the compressed video stream, a novel rate control algorithm based on human visual system (HVS) is proposed in this paper. The proposed rate control algorithm consists of two layers: frame level and basic unit (BU) level. In frame level, changed scene is first detected and frame difference ratio is utilized to represent the motion complexity of the frame, and then target bit for frame level are allocated by considering the two factors. In BU level, by analyzing motion information, texture characteristics and the location of the frames, visual sensitivity of a macroblock is first measured, and the bit is allocated for the macroblock based on the sensitivity factor. Experimental results show that the proposed method can provide an improved visual quality and higher PSNR while almost the same control accuracy, compared with traditional rate control method.
