Before anything else, I'd like to thank the random Samaritan on the internet who was kind enough to provide a detailed article on the build-up of the project. It was immensely helpful. Shoutout to McGill School of Computer Science for providing the Sudoku algorithm.
The GitHub repository hosts an Image-based Sudoku Solver project, combining Computer Vision and Machine Learning. Leveraging OpenCV for image processing and TensorFlow for ML integration, the solver captures real-time video frames to recognize and solve Sudoku puzzles. The repository includes code for contour detection, perspective transformation, and grid recognition, showcasing a comprehensive solution. A pre-trained neural network facilitates accurate digit recognition, making the solver adept at handling diverse puzzles. The project is well-documented, offering insights into its implementation and potential extensions. The integration of Tkinter for a user-friendly interface adds to its accessibility and usability.
This program serves as a way to calculate the solution to any 9x9 sudoku puzzle via webcam. It identifies the puzzle through the webcam, processes it uses OpenCV, runs against a neural network to predict the digits, and runs an efficient sudoku solver to determine the answer. It then displays the answer on the same frame if it is solvable.
PuzzlVision is an innovative project that combines computer vision and machine learning to create an image-based Sudoku solver. The system captures real-time video frames, processes Sudoku grids, and employs a pre-trained neural network for accurate digit recognition, ultimately solving Sudoku puzzles.
