2、tion became more and more concerned.With he use of multimedia teaching,There is a urgent need to replace the traditional keyboard input for handwriting input in order to enhance the efficiency

3、 of classroom teaching.However,because own such characteristics of handwritten mathematical formulas as some math symbols are more similar to each other,and some of the more complex mathematical formula exist

4、s up/down position, identification of handwritten mathematical formula would be relatively difficult. A handwritten mathematical formula recognition system should be divided into two major on the wh
