THE VISIBILITY OF NON-UNIFORM TARGET-BACKGROUND COMPLEXES

Abstract

Experimental studies are reported which involved measuring detection thresholds for targets pre sented against pictoral backgrounds of complexly variable luminance. These studies had three principle objectives. The first was to determine the extent to which it is meaningful to assign a value of ''effective contrast'' to represent the visibility of a target in a target- background complex in which target and background may be of nonuniform luminance. The second objective was to develop a practical device for determining the value of effective contrast of a given target background complex. The final objective involved a study of the luminance characteristics of target-background complexes affecting their visibility.
