Abstract

In this paper, we analyze the limitation of p-domain based rate-quantization (R-Q) model. We find out that a characteristic-based R-Q model can be derived from p-domain to q-domain. Experimental data show that such a characteristic-based R-Q model can provide a more accurate estimation of the actual bitrate than existing models for both frame-level and macroblock(MB)-level. In addition, a simple analysis of computational complexity of our quantizationfree characteristics extraction framework shows that our model is faster than existing variance and p- domain based R-Q models.
