Contrast sensitivity functions (CSFs) characterize the sensitivity of the human visual system
at different spatial scales, but little is known as to how contrast sensitivity for achromatic and …

Human vision works in a complex way in the mesopic luminance range which is not yet
clearly understood, although several important visual tasks are performed at these …

Inspired by the ModelFest and ColorFest data sets, a contrast sensitivity function was
measured for a wide range of adapting luminance levels. The measurements were …

In order to investigate the mechanisms underlying green/red equiluminance matches in
human observers and their relationship to mechanisms subserving luminance and/or …

Mechanisms of light adaptation have been traditionally explained with reference to
psychophysical experimentation. However, the neural substrata involved in those …

The contrast matching function (CMF) is the reciprocal of test contrast that perceptually
matches the contrast of standard pattern, measured as a function of test spatial frequency …

Little is known about how color signals and cone-and rod-based luminance signals
contribute to perceived contrast in the mesopic range. In this study the perceived contrast of …

Contrast sensitivity (CS), the ability to detect small spatial changes of luminance, is a
fundamental aspect of vision. However, while visual acuity is commonly measured in eye …

The color appearance of a light can be altered by introducing a second, surrounding field.
This phenomenon, called chromatic induction, is attenuated by chromatic variation within a …

The contrast sensitivity function (CSF) is a fundamental visual model explaining our ability to
detect small contrast patterns. CSFs found many applications in engineering, where they …
