Abstract

Abstract: Woodcut printing is a painting, in which knife and wood block are used instead of pen and paper. Yunnan out-of-print woodcut is an extension of the woodcut printing. By working with a single block and multiple printings, Yunnan out-of-print woodcut can produce special effects of color overlap. Following the working process of it, an automatic method was studied based on nicks to synthesize a virtual Yunnan out-of-print woodcut. Image was sliced out by using color clustering. A global orientation field was got which reflected the gradient information. Real nicks guided by streamlines was placed based on orientation field. The image rendering was finished by using stylized edges which were got from XDOG. Because nicks from real woodcuts were used, the complicated calculations and modeling could be avoided. The rendering is simple and efficient, while the simulated result looks good.
