Abstract :
The purpose of this technical demonstration is to show how the compressed video quality can be improved by taking the characteristics of human visual system into account in the rate distortion optimization and rate control processes of a video encoder. Both the R-D performance of the video encoder and the picture quality can be evaluated subjectively by the viewers in this demonstration to witness that perceptual video coding is indeed a promising direction for next generation video coding.
