识别手写汉字的基元模糊关系法

Fundamental Units' Fuzzy Relations Approach for Handwritten Chinese Character Recognition

手写汉字中笔划、部件及其位置关系均产生较大变化,这种变化是引起手写汉字特征不稳定的主要因素。为了减小上述不利影响,使手写汉字特征的描述趋于稳定,文章给出了一种基于汉字基元之间的模糊关系识别手写汉字的方法,用汉字基元之间的模糊关系来描述汉字的结构,其优点:一是对汉字基元之间相对位置的变化有较强的适应性,二是不需要对一个汉字中的各个基元在二维平面内进行复杂地排序,汉字的结构可以简化为一个基元模糊关系的集合。

The strokes,components and their position are changed in handwritten Chinese characters,which is the main reason of what makes the features of handwritten Chinese characters unstable.To decrease its unfavorable influence and make the description of the characters' features stable,a handwritten Chinese character recognition method is presented which is based on the Fuzzy relation of Chinese character's fundamental unit in this paper.There are two advantages us-ing fuzzy relations of Chinese character's fundamental unit to describe its structure.One is that it has strong adaptabiliby to relative positions of Chinese character's fundamental units.Another is that it doesn't need to make complex sorting in two dimensional space of Chinese character's each fundamental unit,and the structure of a Chinese character can be simplified as a set of fundamental units' fuzzy relations.
