Abstract

In this paper, we investigate the frequency sensitivity of the human visual system. The human visual system reacts differently at different frequencies. Based on this observation, we used different quantization steps for different frequency components to explore the possibility of improving coding efficiency while maintaining perceptual video quality. In other words, small quantization steps were used for sensitive frequency components while large quantization steps were used for less sensitive frequency components.
