Abstract

The new MPEG-H/H.265 High Ef ciency Video Coding(HEVC) standard greatly promotes the video compression ef ciency and also creates new opportunities and challenges in perceptual video coding. To measure the perceptual quality, Mean Opinion Score (MOS) is obtained by averaging human scores in subjective test. But its value cannot necessarily represent exact difference between the human opinions. To solve this problem, interval MOS (iMOS) method, which employs the distribution information of human scores to measure the difference between MOS values with deviations, is introduced. Furthermore, the feasibility of using iMOS to evaluate compressed video quality is confirmed by experiments.
