DISPLAY AWARENESS IN SUBJECTIVE AND OBJECTIVEVIDEO QUALITY EVALUATION

摘要

Most of studies on video quality assessment are focusedrnon the impact of coding distortion or transmission error.rnIn this paper, display is considered. Regarding technology,rnsome subjective experiments suggest that there are differencesrnin term of quality between LCD and CRT. CRT providesrna better quality when viewing HD video content whilernit is LCD when viewing still colour images. One explanationrnof this behaviour is explained through the LCD motion blur.rnFrom a motion blur perception model, an efficient metric ofrnthe quality loss due to this effect on LCD is proposed. Finally,rnthe results of subjective experiments using SD video contentrnare consistent with a motion-blur-based model and point outrnthat the effect of display technology is linked with the videornresolution.
