Sudoku Solver

Welcome to this Visual Sudoku Solver

This app lets you solve Sudoku puzzles by simply pointing your camera at them. It's a project I built to learn and experiment with computer vision and machine learning.

How to use

1. Point your camera at the Sudoku puzzle.
2. Make sure the whole grid is visible in the camera frame.
3. Hold still for a few seconds while the app works its magic and fills in the missing numbers.

Tips for best results

• Lighting
  Try to use even lighting. Avoid shadows or glare that might mess with the grid detection.
• Angle
  Hold your camera directly above the puzzle. Avoid tilting or weird angles.
• Focus
  Make sure the puzzle is in focus and the numbers are clear.

Known issues

I built this mainly for my own learning, so it's definitely not perfect. Some more common issues are:

• Sometimes, the app has trouble recognizing the grid, especially if the lighting is uneven or the puzzle isn't clear.
• It might occasionally misread parts of the grid, leading to some errors.

If you'd like to learn more about how I built this, I documented a lot of the progress in python notebooks which are available on Github.
