OCR Engine for mathematical expression to latex translation using CNN with AI approach
In this project, includes source code of a neural network for single character recognition and code for train network using keras api. For translation of image to latex form, few steps are required
- Preprocess of whole image
- Seperate single character using contour
- Recognize characters using CNN model
- Translate to Latex with information of their position
Additionally, for application using this engine, we made "Calcuator for Comfort".
