Method of compensating for the effect of undersirable attributes on the measurement of desirable attributes for objective image quality

摘要

A method and apparatus for compensating for the effect of improperly characterizing first image attribute as enhancing a second image attribute during objective image quality measurement of the second image attribute in a video. The method and apparatus determines (10) a quantitative relationship between an objective image quality metric for the first image attribute and an objective image quality metric for the second image attribute; and uses the determined quantitative relationship to compensate (40) the objective image quality metric of the second image attribute for the effects of the first image attribute. Also, a video processing system for automated optimization of video image quality. The system includes a video processing device, which utilizes the present invention, for generating an objective image quality metric. The objective image quality metric is utilized by a video optimization device to adjust parameters of a video enhancement device of the system, which enhances digitized versions of videos.
