Abstract: Discusses research efforts to derive objective measures of video quality that emulate human perception. The derivation of these metrics involves the following steps: (1) a set of test scenes in selected and distorted, (2) a set of candidate objective measures are extracted, (3) a panel of viewers rates the quality of the same set of test scenes, (3) a simultaneous statistical analysis of the subjective and objective data sets reveals which portion of the objective data is meaningful, and how the objective data should be combined to create an overall metric that emulates human perception. 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.
