Abstract: “Color blindness or color vision deficiency (CVD) refers to the inability to perceive or distinguish certain colors or shades of colors to some degree. This paper presents different methods of correcting images especially for people suffering from dichromacy: protanopia, deuteranopia and tritanopia. Color transformation, color simulation and colormap approximation are the methods that have been applied in this project for helping color blind people to improve color perception when they see things in this world. Experimental results demonstrate the effectiveness of the proposed methodology. A survey has been conducted to colorblind people to test the proposed methodology.The output of the survey shows very promising results, indicating that the proposed method of image correction using colormap approximation method is capable of relaying information in the picture or image tothe color blind people.”
