Comparative study of the MTFA, ICS, and SQRI image quality metrics for visual display systems
Robert J. Beaton, Willard W. Farley · Defense Technical Information Center (DTIC) · 1991
This effort was a review of and analytic comparison between several of the most widely reported display image quality metrics: Modulation Transfer Function Area (MTFA), Integrated Contrast Sensitivity (ICS) metric, and the Square-Root Integral (SQRI) metric. Differences were found with regard to weightings applied to the psychovisual data which underline each metric. The SQRI metric was found to be sensitive to many variations in display viewing but was also found to exhibit large computational errors which were difficult to bring into control. The MTFA and ICS metrics were found to be somewhat less sensitive to display viewing parameters but also to exhibit greater computational robustness.
