Handwriting-Calculator

A calculator that uses handwritten digits and operators to calculate the result, using contour detection and CNN model prediction.

  • Tensorflow (Keras) is used to create, train and load the neural network model used for predictions.
  • CustomTKinter is used to provide the GUI.
  • OpenCV and Pillow (PIL) are used to read input from the GUI canvas and to obtain contours for individual digits/operators.
  • The individual digits/operators are detected and predicted. The predictions are combined into a string and evaluated to get the result.
