Spatiotemporal adaptive quantization for an efficient video rate control
Author(s): Si-Woong Lee; Wook-Joong Kim; Kyuheon Kim

Paper Abstract

A new algorithm for the rate control of videos considering the sensitivity of the human visual system (HVS) is presented. The method adopts the three-step structure of MPEG-2 Test Model 5 (TM5) rate control, while a new measure for the macroblock (MB) activity based on spatiotemporal sensitivity is introduced. Experimental results show that the proposed activity measure outperforms the spatial activity of TM5 in picture quality.
