An overview study of various re-coloring and wavelength adjustment algorithm for color vision deficient individuals

Color Blindness which can be also referred as Color Vision Deficiency (CVD) is one of the biggest scaling defect in humans which is still under the research for its accurate detection and cure measures & strategies. Color Blindness is the decreased ability to sight the distinctive colors instantly under normal lighting conditions. There are approximately 250 million individuals who suffer from Color Blindness. So it is need of an hour to understand all the important aspects of the Problem CVD and take the necessary measures to help the People who are knowingly or unknowingly suffering from CVD. In this paper we are going to put light on how exactly color blindness is genetically transferred to children, types in color vision deficiency i.e. Anomalous Trichromacy (protanomaly, deuteranomaly, tritanomaly), Monochromacy and how exactly person sees the normal image under respective CVD and finally put light on few algorithms and strategies which with the help of re-coloring and wavelength shifting actually help the color vision deficient to view and sight all the colors of the actual image distinctively.
