Abstract: Presents an in-depth analysis and discussion of the results from applying the ANSI T1.801.03-1996 objective video quality metrics to subjectively rated MPEG-1 and MPEG-2 video test scenes. The objective metrics presented in ANSI T1.801.03-1996 (American National Standard for Telecommunications - Digital Transport of One-Way Video Signals - Parameters for Objective Performance Assessment) were able to account for 90% of the subjective information that could be captured considering the level of measurement error present in the subjective and objective data sets. By contrast, peak signal to noise ratio (PSNR), a traditional objective metric, was only able to account for 21% of the subjective information.

Keywords: coding; Video; quality; metrics; objective; subjective; correlation; MPEG-2; compression; MPEG; MPEG-1
