Beautifying handwriting characters based on the optimization of strokes and structure

本文提出了一种基于在线手写输入的字形美化方法.首先给定手写体的笔画和拓扑结构的形式化描述;然后借助拓扑结构和笔画的稳定性计算,采用类似轮盘赌的方; 法从用户手写样本中得到最佳的拓扑结构和笔画集,并分别对输入汉字的空间布局和各个笔画进行美化;最后通过分析书法理论中\笔断意连"的几种常见模式,确; 定需要笔断意连的笔画,实现笔画之间的呼应关系优化,从而得到符合书法审美要求的字形.In this paper, we propose a method for beautifying online handwriting; characters. First, we introduce a formalization description of the; handwritings topological structure and strokes. Then, in order to; beautify the spatial arrangement and strokes of the input character, we; capture the writers stability factors for the topology and strokes of; their handwriting, and select a suitable topological structure and; strokes from users handwritten samples, using the roulette wheel method.; In addition, we analyze certain classical stroke connection types as; described in calligraphy theory, and determine which strokes need to; consider visual effects. Finally, we apply curve fitting to optimize the; stroke relations in order to generate a final result that meets the; calligraphy aesthetics requirements.国家自然科学基
