An Intra-Rate Estimation Method for H.264 Rate Control

The paper presented a novel intra-rate estimation method for H.264/AVC rate control. This method establishes the intra-frame rate-quantization (R-Q) estimation model by using gradient-based picture complexity measure. By this R-Q model, the quantization parameters can be accurately obtained. Simulation results show that by using this scheme, better rate control for Intra-frames.
