| Abstract:Aiming at the recognition and calculation of handwritten mathematical formulas, a character training method based on convolutional neural network is proposed. Computer vision is used to preprocess pictures of mathematical formulas, and convolutional neural network is used to perform two-dimensional matrix transformation, and the corresponding character symbols are obtained, and the recognition results are calculated by suffix expressions. The character model is trained by Softmax function, and the recognition and calculation results of several types of mathematical formulas are counted and analyzed. The experimental results show that the correct rate can be effectively improved by training characters, and the method can provide a reference for the recognition and calculation of complex handwritten mathematical formulas. |
