Toru Hiraoka, Masaharu Hirota, Kohei Inoue, Kiichi Urahama, Generating cell-like color images by inverse iris filter, ICIC Express Letters, 11, 2, 399-404, 2017.02, In recent years, non-photorealistic rendering has gathered interest as a technique of computer graphics. As a field of non-photorealistic rendering, researches have been studied actively to generate patterns such as labyrinth and stripe. We propose a non-photorealistic rendering method for generating cell-like color images that are overlaid with cell patterns in photographic color images. Our method generates cell-like color images by an iterative process using an inverse iris filter. To validate the effectiveness of our method, we conduct experiments on a color image of Lena by changing the parameters of the inverse iris filter visually. As an additional experiment, we apply our method to several photographic color images..

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..
