Abstract: Presents preliminary results on the objective to subjective quality correlation for a set of 5 test scenes passed through three systems (NTSC, VHS, and DS1 MPEG coding). One objective metric that correlates well with subjective quality quantifies the amount of false or extra edges that have been added to the output video. There appears to be some advantages to applying the metric separately to the still and motion portions of the video.
