Although luminance and color are thought to be processed independently at early stages of
visual processing, there is evidence that they interact at later stages. For example, chromatic …

The human visual system is remarkably good at decomposing local and global deformations
in the flow of visual information into different perceptual layers, a critical ability for daily tasks …

Second-order visual filters decode spatial modulations of contrast, orientation, and spatial
frequency. Using these mechanisms, we obtain the information necessary for figure …

The primary objective of this thesis was to explore the sensitivity of perception of shape-from-
shading. Concurrently, age-related perceptual and cognitive function were also investigated …

A medida de sensibilidade ao contraste (SC) de primeira ordem é frequentemente utilizada
para avaliação da percepção espacial. Nosso objetivo foi desenvolver e validar um teste de …

Дается краткий исторический обзор исследований зрительных механизмов второго
порядка. Указывается на существующий в настоящее время интерес исследователей к …

Modulations in light intensity across a visual image could be caused by a flat object with
varying pigmentation, such as wallpaper, or differential light reflection from a three …

The combination of functional magnetic resonance imaging (fMRI) and multivariate pattern
analysis (MVPA) is a powerful method for investigating brain function, with multiple MVPA …

In this thesis, I investigated how human vision processes colour and luminance information
to enable perception of our environment. I first tested how colour can alter the perception of …
