摘　　要：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 handwriting＇s 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.

关 键 词：手写体 字形美化 笔断意连 在线 书法
