Automatic Correction for Handwritten Mathemetical Formula

Detecting lines of mathematical problems then solve it!

We develop two kinds of model for recognizing math operators and numbers.

Low-level model: Adpoting BOW + SVM for image classification

CNN-based model: LeNet trained on MNIST

Pipeline is shown below

To improve the accuracy, we extact the skeleton for each element detected.

• Dataset: CROHME of ICFHR14 and MNIST
• Environment: Tensorflow 2.4, Opencv 4.5 and python 3.7+
