ISO 20462-2:2005 defines a standard psychophysical experimental method for subjective image quality assessment of soft copy and hard copy still picture images.
Abstract
Overview
ISO 20462-2:2005 - "Photography - Psychophysical experimental methods for estimating image quality - Part 2: Triplet comparison method" specifies a standardized, for assessing still-image quality of both soft‑copy (displays) and hard‑copy (prints) images. The method is designed to provide of perceived image differences in units tied to just noticeable differences (JNDs), while keeping observer stress low and enabling evaluation of relatively large sample sets.
