计算机辅助数学图形转换为触觉图形的系统对视障人士学习数学和科学有一定的帮助。为了开发这样的系统，需要对数学图形识别技术进行研究。人们很自然地认为：(1)一个数学图形包括用来解释直线或曲线的字符和数学公式，这些直线或曲线是函数或关系的图形表达式；(2)图形有时使用折线绘制。在此假设下，本文讨论了(1)将数学图形分离为字符成分和图形成分，(2)提取每个字符串和数学公式的方法。
Abstract A computer-aided system for transformation of mathematical figures into tactile graphics is useful for the visually impaired when they learn mathematics and science. To develop such a system, a study of mathematical figure recognition techniques is needed. It is natural to assume that (1) a mathematical figure includes characters and mathematical formulas to explain lines or curves that are graphical expressions of functions or relations, and (2) graphs are sometimes drawn using broken lines. Under these assumptions, this paper discusses methods of (1) separating a mathematical figure into the character components and the graph components, and (2) extracting each character string and mathematical formula.
