초록

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