Abstract

In this letter, we present an adaptive intraframe rate-quantization (R-Q) model for H.264/AVC video coding. The proposed method aims at selecting accurate quantization parameters (QP) for intra-coded frames according to the target bit rate. By taking gradient-based frame complexity measure into consideration, the model parameters can be adaptively updated. Experimental results show that when employing our proposed R-Q model, the intraframe target bits mismatch ratio can be reduced by up to 75% as compared to the traditional Cauchy-density-based model. Hence, this is extremely useful for H.264/AVC rate control applications.
