The state-of-the-art JVT-G012 rate control algorithm of H.264 is improved from two aspects. First, the quadratic ratedistortion (R-D) model is modified based on both empirical observations and theoretical analysis. Second, based on the existing physiological and psychological research findings of human vision, the rate control algorithm is optimized by incorporating the main characteristics of the human visual system (HVS) such as contrast sensitivity, multichannel theory, and masking effect… CONTINUE READING
