In this paper, we propose an adaptive intra-frame rate-quantization (R-Q) model for H.264/AVC video coding. The proposed model aims at estimating accurate output bit rate according to the quantization parameters (QP) for intra-coded frames in low bit rate networks such as video sensor networks. By taking frame complexity measure into consideration, the parameters of the proposed model can be adaptively adjusted to the visual contents. In addition, the method of Kalman filtering is used to estimate the model parameters for real-time video encoding applications. It is shown by experimental results that the proposed model predicts the output bit rate accurately and thus achieves better mismatch performance than that of the existing method.
