VisionMath

AI-Powered simple mathematical expression solver

Details

Details on the general process can be found in the PDF presentation and on the JupyterNotebook PDF.

Description

VisionMath takes a handwritten mathematical operation and uses AI to recognize the characters.
Afterward, it builds the operation and returns the corresponding value.

Dependencies

VisionMath was made on Python 3.11 and the packages it requires are:

• OpenCV
• Numpy
• Matplotlib
• Keras
• Scipy

Keras Model

VisionMath uses a Tensorflow Keras model formed by:

1. Flatten Layer (input_shape = (28,28))
2. Dense Layer (units = 128, activation = relu)
3. Dense Layer (units = 128, activation = relu)
4. Dense Layer (units = 13, activation = softmax)
