A color compensation vision system for color-blind people

DOI

Description

In this paper, we propose a color compensation vision system for color-blind people. About 8% of males and less than 1% of females have faulty color perception from birth. The degree to which a person may possess abnormal color vision ranges from slight difficulty in recognizing shades of color to total loss of color vision. Most types of defective color blindness can be classified into two categories: green color defective and red color defective. The population with the blue color defective type is less than 1%. Thus we mainly focus on a color vision compensation system that enables color-blind people to see the colors of green and red. In order to compensate image color for color-blind people, the image in RGB color space is converted to HLS color space which enables the defective color range to be easily avoided. The validity of the proposed method is confirmed by the developed camera and display color compensation system.
