Strokes and Shades for Oriental Stylization

Abstract

In oriental paintings, artists have developed a unique style that exploits the effects of the dispersion of the ink, composed of soot and glue, onto absorbent paper. These artists produce these effects purposely by manipulating the ink concentration, stroke speed and brush angle. We describe these artistic styles of oriental painting and show how we render a single image in the oriental painting style. Our work is to take a single image as input and produce an oriental brushwork-like image automatically as a result. This nonphotorealistic rendering do not have richness of physical painting system such as 3-D brushes but reproduce artistic style of paintings to an image with a speed. In recent years, oriental brushwork rendering have been applied for 3-D objects e.g. Non-photorealistic rendering in Chinese painting of animals by Yeh and Ouhyoung 2002 and stereo images e.g. Humanistic oriental art created using automated computer pocessing and non-photorealistic rendering by Cheok et al. 2007 that require geometric details and depth information, but our method proposes a system that reproduce the styles and effects of oriental paintings from single 2-D image by using a set of image processing techniques. Figure 1 shows an input image and the reproduced oriental paintings. We focus on reproducing the stroke drawing and artistic shades that are essential in conventional oriental paintings.
