Color naming and categorization in inherited color vision deficiencies
Visual Neuroscience, 2006Dichromatic subjects can name colors accurately, even though they cannot discriminate among red-green hues (Jameson & Hurvich, 1978). This result is attributed to a normative language system that dichromatic observers developed by learning subtle visual cues to compensate for their impoverished color system.

Seamless visual sharing with color vision deficiencies
ACM Transactions on Graphics, 2016Approximately 250 million people suffer from color vision deficiency (CVD). They can hardly share the same visual content with normal-vision audiences. In this paper, we propose the first system that allows CVD and normal-vision audiences to share the same visual content simultaneously.

The Genetics of Color Vision and Congenital Color Deficiencies
2016Primates are unique among mammals in possessing trichromacy. In Old World primates, it is based on three cone classes in the retina, each expressing a different class of visual pigment. These pigment classes are each orthologues of pigments present throughout the vertebrate kingdom, the short wavelength-sensitive (SWS1, SWS2, LWS and MWS) pigment and ...

Accessibility for individuals with color vision deficiency
ACM SIGACCESS Accessibility and Computing, 2011Individuals with Color Vision Deficiency (CVD) are often unable to distinguish between colors that individuals without CVD can distinguish. Recoloring tools exist that modify the colors in an image so they are more easily distinguishable for those with CVD.

Texture Recognition for Users with Color Vision Deficiencies
2015In this study, we designed a new type of primary color recognition assistive system for this user group, adding (1) directly perceived labels (the label group), (2) shape and color related dots (the dot group), or (3) distinctive vein lines (the vein group) to help with the recognition of primary colors red, green, and blue.

Visual contents adaptation for color vision deficiency
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004In this paper, we propose methods to adapt colors on the visual content for people with color vision deficiency. The proposed adaptation consists of two parts: adaptations for dichromat and anomalous trichromat. The adaptation for dichromats aims to give them better color information, while the adaptation for anomalous trichromats aims to give them ...

Molecular genetics of colour vision deficiencies
Clinical and Experimental Optometry, 2004The normal X-chromosome-linked color-vision gene array is composed of a single long-wave-sensitive (L-) pigment gene followed by one or more middle-wave-sensitive (M-) pigment genes. The expression of these genes to form L- or M-cones is controlled by the proximal promoter and by the locus control region.

Recoloring Image For Color Vision Deficiency By GANS
2019 IEEE International Conference on Image Processing (ICIP), 2019Compared to normal people who can recognize all colors in 3-D color space, people with Color Vision Deficiency (CVD) just could recognize colors in 2-D color space or only in 1-D color space. Therefore, color version deficient people cannot distinguish some colors under certain circumstances.

Recognition of simulated cyanosis by color-vision-normal and color-vision-deficient subjects
Journal of the Optical Society of America A, 2014There are anecdotal reports that the recognition of cyanosis is difficult for some color-deficient observers. The chromaticity changes of blood with oxygenation in vitro lie close to the dichromatic confusion lines. The chromaticity changes of lips and nail beds measured in vivo are also generally aligned in the same way.

Visual Acuity and Color Vision Deficiency in Amblyopia
European Journal of Ophthalmology, 2000Purpose To investigate color vision and its relation with the type of amblyopia and visual acuity of amblyopic eyes. Methods In this prospective study, 67 amblyopic eyes of 64 patients, aged from 4 to 13 years (mean 6.8 ± 2.1) and 26 ...
