Two-dimensional biocompatible plasmonic contact lenses for color blindness correction

open access: yesScientific Reports, 2022
Color blindness, or color vision deficiency (CVD), is an ocular disease that suppresses the recognition of different colors. Recently, tinted glasses and lenses have been studied as hopeful devices for color blindness correction.

Color Perception: A Correction [PDF]

open access: yesScience, 1893
I hasten to send this note of correction to my paper on ""Distance and Color Perception by Infants"" in Science , April 28—an error brought to my attention by a friend. In Tables I. and II. of that article (p. 231) I have taken the proportion of ""acceptances"" to the entire number of cases (the ratio A/N) after ...

Saliency-based image correction for colorblind patients

open access: yesComputational Visual Media, 2020
Improper functioning, or lack, of human cone cells leads to vision defects, making it impossible for affected persons to distinguish certain colors. Colorblind persons have color perception, but their ability to capture color information differs from ...

Sand-Dust Degraded Image Enhancement Algorithm Based on Histogram Equalization and MSRCR [PDF]

open access: yesJisuanji gongcheng, 2022
To solve the problems of severe image color offset and low contrast in dusty conditions, a sand-dust degraded image enhancement algorithm based on histogram equalization and Multi-Scale Retinex with Color Restoration (MSRCR) is proposed, which primarily ...
