Perceived object colour and material help us to select and interact with objects. Because
there is no simple mapping between the pattern of an object's image on the retina and its …

Vision researchers are interested in mapping complex physical stimuli to perceptual
dimensions. Such a mapping can be constructed using multidimensional psychophysical …

The human visual system is able to rapidly and accurately infer the material properties of
objects and surfaces in the world. Yet an inverse optics approach—estimating the bi …

Psychophysical approaches that allow us to estimate how perceived stimulus intensity is
linked to physical intensity are import tools for studying nonlinear transformations of visual …

While much attention has been given to understanding biases in gloss perception (eg,
changes in perceived reflectance as a function of lighting, shape, viewpoint, and other …

Visual material perception is often studied with physically well-defined stimuli that lack
ecological variety. Yet, even the visual variety found in our natural environment is limited …

In this article, we address the problem of measuring and analyzing sensation, the subjective
magnitude of one's experience. We do this in the context of the method of triads: The …

Recent advances in computational models in vision science have considerably furthered our
understanding of human visual perception. At the same time, rapid advances in …

A central question in psychophysical research is how perceptual differences between stimuli
translate into physical differences and vice versa. Characterizing such a psychophysical …

One central problem in perception research is to understand how internal experiences are
linked to physical variables. Most commonly, this relationship is measured using the method …
