Abstract
A method, system and computer program product for assessing quality of images or videos. A quality assessment of an image or video to be processed is performed using a no-reference reference quality assessment algorithm. A quality measurement, such as a score, reflecting the quality of the image or video, is generated from the no-reference reference quality assessment algorithm. The image or video is then processed and a quality assessment of the processed image or video is performed using a reference quality assessment algorithm that is conditional on the quality measurement provided by the no-reference quality assessment algorithm. In this manner, a more accurate quality measurement of the image or video is provided by the reference quality assessment algorithm.
