Visual search in the real world: Color vision deficiency affects peripheral guidance, but leaves foveal verification largely unaffected

open access: yesFrontiers in Human Neuroscience, 2015
Background: People with color vision deficiencies report numerous limitations in daily life. However, they use basic color terms systematically and in a similar manner as people with people with normal color vision.

Spatial summation of individual cones in human color vision. [PDF]

open access: yes, 2019
The human retina contains three classes of cone photoreceptors each sensitive to different portions of the visual spectrum: long (L), medium (M) and short (S) wavelengths. Color information is computed by downstream neurons that compare relative activity

Wearable Improved Vision System for Color Vision Deficiency Correction

open access: yesIEEE Journal of Translational Engineering in Health and Medicine, 2017
Color vision deficiency (CVD) is an extremely frequent vision impairment that compromises the ability to recognize colors. In order to improve color vision in a subject with CVD, we designed and developed a wearable improved vision system based on an ...

Color Vision in Aniridia

open access: yesInvestigative Opthalmology & Visual Science, 2018
To assess color vision and its association with retinal structure in persons with congenital aniridia.We included 36 persons with congenital aniridia (10-66 years), and 52 healthy, normal trichromatic controls (10-74 years) in the study. Color vision was assessed with Hardy-Rand-Rittler (HRR) pseudo-isochromatic plates (4th ed., 2002); Cambridge Color ...

Color Vision Improvement of Anomalous Trichromats Based on a Wide-Color-Gamut Display

open access: yesIEEE Photonics Journal, 2022
Compared with normal color vision observers (NOs), anomalous trichromats (AT) have anomalous color vision responses owing to differences in cone sensitivity. The wide-color-gamut display provides a promising solution to this problem. Herein, we propose a

Accessibility-based reranking in multimedia search engines [PDF]

open access: yes, 2016
Traditional multimedia search engines retrieve results based mostly on the query submitted by the user, or using a log of previous searches to provide personalized results, while not considering the accessibility of the results for users with vision or ...

Color Vision Deficits

open access: yesCurrent Neurology and Neuroscience Reports, 2021
Color provides important information about the identity of the objects we encounter. After early processing stages in the retinal cones, thalamus, and occipital cortex, retinal signals reach the ventral temporal cortex for high-level color and object processing, which links color perception with top-down expectations and knowledge.
