摘要：
A subjective quality test was undertaken to quantify the amount by which the perceived quality of full-face digital video (such as a newsreader) varies with the spatial location of degradation. It was found that perceived error was greatest for degradation occurring around the eyes and mouth. Traditional digital video assessment techniques, such as peak signal-to-noise ratio, rate all errors equally, irrespective of spatial location and thus do not give a meaningful measure of perceived quality.
