A psychophysical approach to image quality

Abstract

Whether an image is produced on a CRT display, a printer, or a photographic plate, that image can be described as a two-dimensional modulation of luminance and color across space. A psychophysical approach to image quality is one which considers the detectability and discriminability of these images in terms of the spatial, temporal, and color-sensitive mechanisms of perception. The aim is to develop a technology-independent method for characterizing and predicting image quality. © 1985 SPIE.
