Kohei Inoue, Kenji Hara, kiichi urahama, Applying Color Schemes to Color Images with Unilateral Filter, Journal of the Institute of Industrial Applications Engineers, vol. 4, no. 3, pp. 118-121, 2016.07, We propose a method for applying a color scheme to a color image with a unilateral filter (UF) which outputs at each pixel of an image the weighted average of neighboring colors in RGB color space. The proposed UF is a generalization of range filter which is a special case of bilateral filter. Experimental results show that the proposed method can change the colors of given images into other colors specified by given color schemes. The effectiveness of the proposed color scheme application is objectively evaluated for some color images. We also apply UF to color image enhancement such as saturation and contrast enhancement..
