Lightness perception is the perception of achromatic surface colors: black, white, and
shades of grey. Lightness has long been a central research topic in experimental …

Background Previous studies have suggested that processing of visual contrast information
could be altered in major depressive disorder. To clarify the changes at different levels of the …

Visual illusions teach us that what we see is not always what is represented in the physical
world. Their special nature make them a fascinating tool to test and validate any new vision …

Illusions are often considered to be a misperception of the physical world. We present a
different framework for illusions: in non-illusory conditions, healthy brains construct a single …

Lightness perception is the ability to perceive black, white, and gray surface colors in a wide
range of lighting conditions and contexts. This ability is fundamental for any biological or …

Human vision relies on mechanisms that respond to luminance edges in space and time.
Most edge models use orientation-selective mechanisms on multiple spatial scales and …

The perception and evaluation of art might be governed by both stimulus-driven aspects and
expectations of the observer. By framing actual artwork and actual scientific depictions as …

A key question in perception research is how stimulus variations translate into perceptual
magnitudes, that is, the perceptual encoding process. As experimenters, we cannot probe …

The visual system is highly sensitive to spatial context for encoding luminance patterns.
Context sensitivity inspired the proposal of many neural mechanisms for explaining the …

Murray recently introduced a novel computational lightness model, Markov illuminance and
reflectance (MIR). MIR is a promising new approach that simulates human lightness …
