Improving Discrimination in Color Vision Deficiency by Image Re-Coloring [PDF]

open access: goldItalian National Conference on Sensors, 2019
People with color vision deficiency (CVD) cannot observe the colorful world due to the damage of color reception nerves. In this work, we present an image enhancement approach to assist colorblind people to identify the colors they are not able to ...
