Generation of Reaction-Diffusion-Pattern-Like Images with Partially Variable Size

We propose a non-photorealistic rendering method to au-tomatically generate reaction-diffusion-pattern-like images from photo-graphic images. The proposed method uses smoothing filter with a cir-cular window, and changes the size of the circular window depending on the position in photographic images. By partially changing the size of the circular window, the size of reaction-diffusion patterns can be changed par-tially. To verify the effectiveness of the proposed method, experiments were conducted to apply the proposed method to various photographic images.
