摘要

An accurate macroblock (MB) layer rate control scheme based on Sobel edge operator for H.264/AVC is proposed. Utilizing the Sobel edge operator, the prediction accuracy of both mean absolute difference (MAD) and header bits can be improved. Meanwhile, a more suitable Rate Quantization (R-Q) model history data point selection method is also developed to enhance the accuracy of R-Q model. Extensive simulations show that the scheme can control bit rates accurately with the average peak signal-to-noise ratio (PSNR) up to 0.8dB when compared with the conventional H.264/AVC rate control algorithms.
