Color vision deficiencies (CVDs), more commonly known as color blindness, are often caused by genetics and affect the cones on the retina. Approximately 4.5% of the world’s population (8% of males) has some form of CVD. Since it is hard for people with CVD to distinguish between certain colors, there might be a severe loss of information when presenting them with images as, e.g., reds and greens may be indistinguishable.
We propose a novel, real-time algorithm for recoloring images to improve the experience for a color vision deficient observer. The output is temporally stable and preserves luminance, the most important visual cue. It runs in 0.2 ms per frame on a GPU.
