Determinants of Perceived Skin-Color Discrimination in Latin America
, 2014
"... Discrimination on the basis of skin color persists as a serious social and political problem in many of the world's nations. Although numerous consequences of such discrimination have been enumerated, considerably less is known regarding the bases of perceived discrimination. In this study, in ..."

An Engineering Model for Color Discriminability as a Function of Size
"... This work describes a first step towards the creation of an engineering model for color discriminability as a function of size. Our approach is to non-uniformly scale CIELAB using data from crowd-sourced experiments, such as those run on Amazon Turk. In such experiments, the inevitable variations in ..."

Color Discrimination in the Tufted Capuchin Monkey, Sapajus spp
"... The present study evaluated the efficacy of an adapted version of the Mollon-Reffin test for the behavioral investigation of color vision in capuchin monkeys. Ten tufted capuchin monkeys (Sapajus spp., formerly referred to as Cebus apella) had their DNA analyzed and were characterized as the followi ..."

horizontally oriented and parallel to each other. The observed phenotypic differentiation confirmed the efficacy of the Mollon-Reffin test paradigm as a useful tool for evaluating color discrimination in nonhuman primates. Especially noteworthy was the demonstration of behavioral segregation between
Effects of high-color-discrimination capability spectra on color-deficient vision
, 2013
"... Light sources with three spectral bands in specific spectral positions are known to have high-color-discrimination capability. W. A. Thornton hypothesized that they may also enhance color discrimination for color-deficient observers. This hypothesis was tested here by comparing the Rösch–MacAdam col ..."

Effects of chromatic adaptation on color discrimination and color appearance,’’ Vision Res
, 1979
"... Abstract-Color discrimination and color appearance were examined at a number of chromaticities along an equal luminance line running from red to green as a function of adaptation to several lights along the same line. Like K. J. W. Craik's results for brightness discrimination [ J. Physiol. 92, ..."

Evaluating Color Descriptors for Object and Scene Recognition
, 2010
"... Image category recognition is important to access visual information on the level of objects and scene types. So far, intensity-based descriptors have been widely used for feature extraction at salient points. To increase illumination invariance and discriminative power, color descriptors have been ..."

Relating color discrimination to photopigment genes in deutan observers
, 1997
"... Deutan observers are a heterogeneous group, varying nearly continuously from deuteranomalous trichromats with fine chromatic discrimination in the red:green range to deuteranopes who have none. We sought to relate chromatic discriminative ability among deutans measured psychophysically (phenotypes) ..."

Color Discrimination Involves Ventral and Dorsal Stream Visual Areas
"... We used positron emission tomography (PET) and functional mag-netic resonance imaging (fMRI) in human subjects to investigate whether the ventral and dorsal visual stream cooperate when active judgements about color have to be made. Color was used as the attribute, because it is processed primarily ..."

in the ventral stream. The centrally positioned stimuli were equiluminant shades of brown. The successive color discrimination task was contrasted to a dimming detection task, in which retinal input was identical but with double the number of motor responses. The stimulus presentation rate was parametrically
Do common mechanisms of adaptation mediate color discrimination and appearance? Uniform backgrounds
- JOSA A
, 2005
"... Color vision is useful for detecting surface boundaries and identifying objects. Are the signals used to perform these two functions processed by common mechanisms, or has the visual system optimized its processing separately for each task? We measured the effect of mean chromaticity and luminance o ..."

on color discriminability and on color appearance under well-matched stimulus conditions. In the discrimination experiments, a pedestal spot was presented in one interval and a pedestal + test in a second. Observers indicated which interval contained the test. In the appearance experiments, observers
