Contrast and Phase Combination in Binocular Vision [PDF]
PLoS ONE, 2010 How the visual system combines information from the two eyes to form a unitary binocular representation of the external world is a fundamental question in vision science that has been the focus of many psychophysical and physiological investigations.

A Biomimetic Model of Adaptive Contrast Vision Enhancement from Mantis Shrimp. [PDF]
Sensors (Basel), 2020 Mantis shrimp have complex visual sensors, and thus, they have both color vision and polarization vision, and are adept at using polarization information for visual tasks, such as finding prey. In addition, mantis shrimp, almost unique among animals, can

Von Bezold assimilation effect reverses in stereoscopic conditions [PDF]
, 2004 Lightness contrast and lightness assimilation are opposite phenomena: in contrast, grey targets appear darker when bordering bright surfaces (inducers) rather than dark ones; in assimilation, the opposite occurs.

Neural Mechanisms for Drosophila Contrast Vision [PDF]
Neuron, 2015 Spatial contrast, the difference in adjacent luminance values, provides information about objects, textures, and motion and supports diverse visual behaviors. Contrast computation is therefore an essential element of visual processing. The underlying mechanisms, however, are poorly understood.

Higher order color mechanisms : Evidence from noise-masking experiments in cone contrast space [PDF]
, 2013 This study addresses a fundamental question concerning the number of cortical, i.e., higher order mechanisms in color vision. The initial subcortical stages in color vision can be described by three cone mechanisms, S, M, L, and three pairs of second ...

A spatial contrast retina with on-chip calibration for neuromorphic spike-based AER vision systems [PDF]
, 2007 We present a 32 32 pixels contrast retina microchip that provides its output as an address event representation (AER) stream. Spatial contrast is computed as the ratio between pixel photocurrent and a local average between neighboring pixels obtained ...
