Review of Psychophysically-Based Image Quality Metrics.

摘要

There have been many advances in imaging technologies resulting in a variety of techniques for generation, coding for transmission, image processing, decoding, and display of information. In addition to the development of techniques, investigators have recognized the need for quantitative measures of image distortion and/or image quality corresponding to observer performance and observer impressions of the images. The purpose of this report is to review current psychophysically based measures of image quality for possible application to compressed or transmitted sensory imagery. This report briefly reviews human vision models, image quality metrics, empirical modelling approaches to image quality, discusses current research needs and provides recommendations for immediate application to compressed digital images.
