An Improved Dynamic Daltonization for Color-Blinds

Color-blindness is an inherited condition which leads to the sufferer not being able to distinguish between certain colors. One of the most widely used algorithms for enhancing a color-blind's color perception of images is Daltonization. Non-iterative Daltonization leaves the possibility of modifying imperceptible colors into colors that already exist in an image. Iterative Daltonization method provides better results by overcoming this problem. This paper presents a new iterative Daltonization method for protanopes which uses hue to ensure imperceptible colors are not modified into colors similar to existing perceptible ones. Experimental results show that the proposed method outperforms similar existing methods.
