Abstract :
In this paper, an improve rate control algorithm for H.264 is proposed which takes image complexity and motion information into consideration to predict the Mean Absolute Difference (MAD). The changes of MAD are adopted to represent the image complexity, and compute the target bit of the current basic unit. Experimental results show that compared with the algorithms of JVT-G012, the bitrate of proposed algorithm is closer to the target bit, and the average of peak signal to noise ratio (PSNR) is improved 0.2183dB.
