Abstract

Color is a perceptual attribute that allows organisms to identify and to locate environmental patterns of equal brightnesses and constitutes an additional dimension in object identification, in addition to the detection of several other object dimensions in relation with the visual scene. Color therefore serves an important role in animal and human interaction with the environment. By supplying ways to evaluate aspects of human vision, including color vision, visual psychophysics focusses on the quantitative study of the relation between physical events of sensory stimulation and the resulting behavioral response. The objective of this paper is to demonstrate several efficient techniques in the evaluation of the chromatic human vision through adaptive psychophysical methods.
