Paper Abstract

The experiment described in this paper was designed to evaluate, in a statistically valid manner, the relative image quality of nine digital images (algorithms) and two film images (laser print and duplicate positive). Three important (and basically different) modes of presenting imagery were compared: a duplicate positive film, a laser film print of a digital image, and a CRT display of the digital images. Imagery was selected in coordination with the Army to assure the tactical relevance of the questions and imagery chosen. Five operational interpreters, having from two to five years experience, took part in the experiment as image quality evaluators. For any particular image question, there were eleven (two film and nine digital) versions of the image on which to judge relative image quality. Each interpreter examined all eleven versions in a pairwise (i.e., two-at-a-time) fashion and specified both the version preferred and the strength of the preference. The interpreter was asked to evaluate the imagery relative to a particular question. For example, a question might be in which image could the interpreter most easily see the wheels on a vehicle. In addition to target-specific questions, there were also general questions on the overall interpretability of scenes.
