Abstract: Recently, it has become increasingly important to devise video quality/distortion measurement algorithms that help to evaluate, compare and improve video coding techniques, and hence to provide effective digital quality video services. This paper introduces a practical model for objective visual distortion measurement of compressed videos. The model is established by making use of both spatial and temporal human visual system (HVS) features, which include spatial frequency sensitivity, luminance masking, texture masking, temporal frequency sensitivity, and short-term memory effect. A ‘Video Compare’ software is developed to demonstrate the system.
