Abstract

We present a method for enhancing the color recognition ability of dichromats. Whereas trichromats (usual people) recognize all colors in a 3-D color space, dichromats only recognize colors on a degenerate 2-D space in it. Our method compensates for the lost information along the degenerate direction in the color space with the amount of noise in the image. Dichromats recognize the lost color information as noisy textures, while the original color information for trichromats is preserved. Our method is applicable not only to artificial figures such as graphs but also to natural photographs. We show the effectiveness of our method by experiments.
