Visual perception is essential to marketing practice and theory. Based on literature in
marketing and related fields, this article develops a conceptual framework comprising five …

The problem of color constancy may be solved if we can recover the physical properties of
illuminants and surfaces from photosensor responses. We consider this problem within the …

A principle of perceptual organization, called uniform connectedness (UC), is described, and
a theoretical approach to perceptual organization is proposed in which this principle plays a …

To understand the computations performed by the input layers of cortical structures, it is
essential to determine the relationship between sensory-evoked synaptic input and the …

A review of the field of lightness perception from Helmholtz to the present shows the most
adequate theories of lightness perception to be the intrinsic image models. Nevertheless …

How the human visual system determines the lightness of a surface, that is, its whiteness,
blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even …

Perceptual anti-individualism-sometimes called externalism about perception-is very old,
stemming as it does from Aristotle. In the history of philosophy it has been the dominant …

Color constancy is our ability to perceive constant surface colors despite changes in
illumination. Although color constancy has been studied extensively, its mechanisms are still …

Visual perception is fundamentally ambiguous because an infinite number of three-
dimensional scenes are consistent with our retinal images. To circumvent these ambiguities …

Most empirical work on color constancy is based on simple laboratory models of natural
viewing conditions. These typically consist of spots seen against uniform backgrounds or …
