Subjective Image Quality Assessment—Theory and Practice
Jonathan B. Phillips, Henrik Eliasson · 2017
Chapter 5 defines the subjective methodologies that relate directly to obtaining meaningful subjective evaluation for still and video image quality. A review of key psychophysical techniques such as category scaling, paired comparisons, acceptability ratings, and mean opinion score will emphasize the strengths and weaknesses of each methodology. The review will also explore the similarities and differences between still and video subjective evaluation techniques. Particular focus will be on the anchor scale method and how that can be used to quantify overall image quality in just noticeable differences for still images.
