Abstract(ENG)

This paper presents non-photorealistic rendering methods of hedcut-style effects by using reaction-diffusion model. Reaction-diffusion model is a mathematical model proposed by Turing to describe the biological formation of natural patterns but we adapted this model as a tonal depiction method of stipples and curve patterns. According to the input image brightness, this model generates stipple patterns of black or white dots for near-black or near-white image area while it produces curve patterns for middle gray image area. Our method uses simple pre-processing step to compensate brightness and contrast of input image. We compare previous method and hand-made hedcut artwork with our results. Our works can be applied in game application and stylized rendering area.
