Pattern detection is the bedrock of modern vision science. Nearly half a century ago,
psychophysicists advocated a quantitative theoretical framework that connected visual …

One of the major goals of sensory neuroscience is to understand how an organism's
perceptual abilities relate to the underlying physiology. To this end, we derived equations to …

The accuracy with which the brain can infer the value of a stimulus variable depends on both
the amount of stimulus information that is represented in sensory neurons (encoding) and …

The processing of texture patterns has been characterized by a model that first filters the
image to isolate one texture component, then applies a rectifying nonlinearity that converts …

Contrast discrimination determines the threshold contrast required to distinguish between
two suprathreshold visual stimuli. It is typically measured using sine-wave gratings. We first …

Contrast is the most fundamental property of images. Consequently, any comprehensive
model of biological vision must incorporate this attribute and provide a veritable description …

Natural scenes are composed of first-order and second-order information. First-order
information is defined by variations in luminance or chromaticity, while second-order …

Coherent motion detection is greatly enhanced by the synchronous presentation of a static
surround (Linares, Motoyoshi, & Nishida, 2012). To further understand this contextual …

Despite its key role in cognition, the mechanisms underlying working memory remain much
debated. It has often been observed that human performance on memory tasks is severely …
