Subjective constancy, or perceptual constancy, is a phenomenon in which our perception of an object or quality remains constant even when our sensory experience of the object varies. Although the physical properties of the object may be unchanged, our perceptual system uses various mechanisms to adjust to the stimulus, allowing us to perceive it as stable and constant.
Of particular importance in visual perception are Wallach''s ratio principle and illumination invariance, which have been described through functional equations and explored in terms of discrimination probabilities with a psychophysical representation.
While the ratio principle was found to be important for chromatic stimuli, [Bäuml, 1993], [Bäuml,1994] also revealed small asymmetries in each opponent channel’s perceived lightness concerning their opponent hues. This suggests that the ratio principle might not be entirely symmetrical and could have some exceptions in certain chromatic perception conditions.
Our hypothesis is that, while the ratio principle is somewhat important for the perception of chromatic colors, color constancy is more likely to play a role here. This conjecture is supported by [Kraft and Brainard, 1999]. Accordingly, one of the main objectives of this PhD topic is to investigate models related to various constancies under certain psychophysical representations.
