用马尔可夫随机场理论生成草书“飞白”纹理

Generating half-dry stroke texture for cursive style calligraphy with Markov random field

针对中国书法"飞白"效果独特而复杂的纹理特征,提出了一种非交互式的书法模拟算法。该算法利用马尔可夫随机场理论和纹理映射技术,从书法家的"飞白"作品中采集一些典型的单字作为样图,以草书系统字体作为目标图,在已确定的目标图的笔道中分层映射样图纹理,从而达到生成草书"飞白"纹理的目的。实验结果表明,该算法能产生与原作品风格趋近于一致的书法汉字效果,实现了用计算机自动生成中国书法作品"飞白"效果的功能。

Half-dry stroke has a special effect in Chinese calligraphy. To simulate the special and complex texture, an algorithm employing the non-interactive means is presented. Markov random field and mapping technology are used in the algorithm. Based on the sample image collected from hand-written artworks and object images drawed from system cursive style, the selected sample image texture is mapped to the strokes in the object image delaminatly. Finally, the half-dry stroke texture is generated. Experimental results demonstrate the method can produce the similar style of the former calligraphy characters. Furthermore, it also proves that computer can simulate the half-dry stroke effect automatically.
