摘要
为了开发一款在Android平板电脑上运行的手写数学公式识别的软件,首先采用特征值多级分类方法对手写字符进行识别;然后提出一种使用三叉结点结构存储数学公式的算法,将手写数学公式转换成一棵三叉树;最后利用三叉树的先序算法将三叉树转换成MathML语言即可在Web浏览器上显示。
In order to develop handwritten mathematical formula recognition software for Android pad,we first adopt the eigenvalue multistage classification method in handwritten characters recognition,and then propose an algorithm of storing the mathematical formula with ternary node structure,which converts the handwritten mathematical formula to a ternary-tree. Finally,we utilise the preorder traversal algorithm of ternary-tree to transform the ternary-tree to MathML and thus he handwritten formula can be displayed on Web browser.
