Paper Abstract

This paper describes experiments to examine the role of color contrast in target identification and signal detection. Current models quantify the image quality of the achromatic visual channel. However, a chromatic map is also created in the visual cortex. The chromatic map has lower spatial resolution than the achromatic channel. The chromatic and achromatic channels are somehow combined in the visual cortex to provide a full-resolution, colored scene. Adding color to the current target acquisition model requires answering two primary questions. First, does color contribute to feature discrimination? Second, what are the spatial and sensitivity characteristics of color perception? This paper describes experiments to determine color contribution to object identification.
