    We propose a non-photorealistic rendering method for generating sand picture-like images from photographs. The proposed method is performed in two steps. First, images with flow patterns created from finger tracing are generated with an anisotropic filter. Second, sand-pattern images are generated with a new filter called "sand filter" which incorporates the idea of iris filters. The new filter has a characteristic emphasizing images including low contrast parts. Therefore, it is possible to generate images like sand picture drawings.
