Daltonization is a procedure of color adaptation in an image to improve the color perception for a color-blind viewer. This paper presents a fast daltonization algorithm for protanopes who cannot distinguish the color between red and green. In the proposed algorithm, the protanope-unperceptible (PU) colors are identified in an image and then converted into new protanope-perceptible (PP) colors by a fast daltonization method that utilizes the color clustering to rapidly measure the color similarity. Experimental results indicate that the proposed algorithm performs better than the conventional method in terms of both color perceptibility and computational complexity.
