Abstract
<p class="0abstract">Color blind is a type of Color Vision Deficiency, which is the inability that a person could not realize the differences between some colors. There are three types of color blindness: Monochromacy, Dichromacy, and Anomalous Trichromacy. Color blind cannot be cured. Today, technology gets up with solutions to help people with color blindness to see the image and distinguish between the different colors using some algorithms. This paper presents a smartphone based experimental comparison of color correction algorithms for Dichromacy color-blind viewers. This comparison includes LMS Daltonization algorithm, Color-blind Filter Service (CBFS) algorithm, LAB color corrector algorithm, and the shifting color algorithm. The description of the smartphone based implementation details and parameters settings of these algorithms is presented. An application interface is implemented to enable the user to choose the algorithm that gives the most appropriate results. The results of these algorithms are compared to see their strength and weakness.</p>
Highlights
Color blindness affects approximately 1 in 12 men and 1 in 200 women in the world
The LMS algorithm only changes color of confused areas with no change in the brightness, while almost all colors of the image are changed by the Color-blind Filter Service (CBFS) algorithm
Unlike the CBFS proceeded images, in the LMS processed images, different colors are converted to different colors after processing
Summary
Color blindness affects approximately 1 in 12 men and 1 in 200 women in the world. Most people with color blindness have an ability to see things as clearly as other people but they unable to see red, green or blue light clearly. There are extremely rare cases where people are unable to see any color at all [1], [2]. For the most people with color vision deficiency, the condition is genetic and has been inherited from their mother. There are some diseases causing color blindness such as diabetes and multiple sclerosis or acquiring the condition over time due to the aging process, medication and so on [1], [2]
