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.
