Paper Abstract

Research has been conducted in Perkin-Elmer's laboratories over a several year period in an attempt to assess existing summary measures of image quality and to evolve new measures. A properly validated image quality measure would allow prediction of quality from an information content viewpoint that may be used in the synthesis, design, or evaluation of electro-optical sampled image systems. To further this goal, a set of psychovisual ranking experiments are presented and described in this paper. These experiments are intended to determine the influence of the sampling process, optical transfer function (OTF) shape, and OTF anisotropy on subjective image quality of sampled image systems. A description is given of the methods of experimentation employed, the procedure for providing a series of sensitometrically calibrated standards and test images for rank-ordering experiments, and the results of the tests that were performed. In addition, this paper summarizes an analysis of experimenter rankings to determine the degree of agreement (coefficient of concordance) among observers.
