基于纹理映射的方法实现书法的“飞白”效果

Realization of half-dry stroke effect in calligraphy based on texture mapping

为了有效地模拟中国书法作品的"飞白"艺术效果,提出了一种基于样图的纹理映射方法。该算法采用形态学的方法对样图进行分割以保留样图的原始风格特征,通过仿射变换将样图的风格传输到目标图中,对得到的目标图进行概貌和细节纹理的划分后在多层次上实现艺术风格的模拟。该方法以书法家的"飞白"体作为样图对Windows操作系统中的行书和草书这两种系统字体进行风格转换,得到了比较理想的效果,表明了本算法的有效性。

To simulate Chinese calligraphy half-dry stroke effect, an algorithm of texture mapping based on the sample image is presented. In the algorithm, the morphology method is used to segment the sample image to retain the original artistic style of it. Calligraphy styles can be transferred automatically from the sample image to the target image by the affine transforms, then the target image is divided into approximation and detail texture, the artistic style is simulated by subdivision of strokes. The half-dry stroke effect from the calligraphers is transferred into Windows system running hand and cursive styles, the experimental result prove the validity of the method.
