Abstract
Much of the work on visual quality assessment has been devoted to gray-level images; metrics taking into account color information and the temporal component are still relatively rare. This paper presents a quality metric for color video which is based on a recent contrast gain control model of the human visual system. It is used to assess the quality of MPEG-coded sequences and exhibits a behavior that is consistent with subjective ratings
