Visibility improvement of undiscriminatable colors by modification of yellow-blue components for protanopia and deuteranopia

Needless to say, the color information plays an important role in the human visual information processing system. However, the color is not be always perceived equally by all the people. There are some people with color vision deficiency, such as dichromacy. They feel the difficulty to recognize and distinguish certain color combinations. In this paper, a visibility improvement method realizing the barrier-free color vision is proposed especially for the protanopia and deuteranopia. The effectiveness of the proposed method is verified by some experiments.
