Abstract

In H.264/AVC, rate distortion (R-D) model plays an important role in rate control and mode decision for efficient video compression. In general, R-D model includes rate quantization (R-Q) model and distortion quantization (D-Q) model. We have already had a study on frame-level D-Q model in the past, it is meaningful for frame level rate control optimization. However, basic unit level R-D model is crucial for precise rate control and efficient mode decision. Therefore, it is necessary to make in-depth analysis on D-Q model at MB level. In this paper, we test several existing D-Q models and give fair comparison on these models, and have an in-depth study on D-Q modeling from accuracy, complexity and applications. Finally, we have shown advantages and disadvantages of these models. This work is meaningful for efficient video coding algorithm optimization in the future.
