We propose a method for generating wallpaper-group images that are generated geometric patterns in the lattices and seamlessly joined patterns between the lattices. The proposed method generates wallpaper-group images by an iterative process using contour line and Euclidean distance. Wallpaper-group images that are generated by the proposed method are characterized that can generate various patterns by the number of iterations. Through the experiment to generate grayscale wallpaper-group images in the image of 500 * 500 pixel size of 50 pixel interval, we verify various patterns by the number of iterations. In addition, by generating color wallpaper-group images which are assigned red, green and blue to three grayscale wallpaper-group images respectively, we also verify that the visual effect is improved.
