摘要: 木刻版画是一种以刀为笔,以板为纸的绘画艺术,云南绝版套刻是它的一种延伸。通过在同一块木板上的多次套印而产生色彩重叠的效果。结合云南绝版套刻的创作过程,我们提出一种自动化的基于刻痕的云南绝版套刻的数字模拟合成方法。通过颜色聚类将图像分割,求出一个平滑的反应图像梯度变化的向量场,根据向量场自动生成均匀分布的流线图,再在流线图上放置刻痕,结合XDOG方法生成的风格化边缘完成图像的绘制。由于使用了取自于真实木刻画中的刻痕,避免了复杂的建模与计算,绘制过程简单快速,无需复杂的人机交互,模拟结果较好。

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.

Key words: Yunnan out-of-print woodcuts, woodcuts, orientation field, XDOG
