| 摘 要： | 文章根据笔写数学公式中字符或符号间空间关系的特点,提出了一种识别方法。首先,对数学公式中的字符和符号进行分类,对每一类提出了相应的正上和正下关系识别方法,然后应用模糊识别的方法对常见关系进行识别。因为根号的特殊性,它被作为一种特殊情况加以处理。实验表明,识别的正确率可达到93.4%。

| Abstract: | A method for recognizing the spatial relationship between symbols or characters in mathematical expressions is proposed according to their characteristic.First,the symbols or characters are classified,the corresponding method for recognizing the above and below relationship is presented.Then a fuzzy method is applied to the familiar relationship. The root is handled alone due to its particularity.The experiment shows that the precision rate is 93.4%. |
