Abstract
Vision is particularly important among the senses that humans perceive, and among them, the sense of color is called color vision. Since color blindness is characterized by color vision, color discrimination may be difficult and may interfere with daily life. Therefore, image color conversion is performed to facilitate color discrimination. However, since general color conversion does not preserve the hue of an image, the resulting image is unnatural for people with general color vision. In this research, brightness correction is performed on the equi-hue plane in the RGB space. Saturation is corrected according to the position of the pixel on the constant hue plane. This enables natural color conversion considering the color distance between pixels while preserving the hue of the image. We verify the effectiveness of the proposed method through various experiments.
