Show HN: Visual Sudoku Solver in the Browser (With OpenCV and TensorFlow)

Hello!

I recently wanted to learn a bit about computer vision. Initially, I wanted to build something which could solve a jigsaw puzzle, but figured I should start with something (much) simpler, so I've built this instead.

This is a visual Sudoku solver which runs in the browser. It works by using OpenCV to identify and process the Sudoku grid, passing this to a simple ML model to identify the digits, and then solving the puzzle with a backtracking algorithm. The ML model was trained on

Show HN: Mailik – Effortlessly Receive Form Responses in Your Inbox
