Augmented Reality In The Browser - This blog showcases the progress of my idea to create an augmented reality Sudoku solver using technology that enables us to solve puzzles in our browser rather than with dedicated apps. I have developed an AR Sudoku solver with a simple image processing pipeline. It identifies and extracts Sudoku puzzles from pictures, recognizes each cell's numbers, solves the puzzle, and renders the solution on top of the original image. This process is accomplished by converting the image to greyscale, conducting thresholding, OCR-processing, and puzzle-solving. I've also done parallel image location and extraction. It's a technical journey that's achieved some high-quality, low-drift results, visible in the video included. The full codebase is accessible on Github. Enjoy the joy of leveraging technology to efficiently solve Sudoku puzzles!

Updating Sudoku Grab - Currently, I am revitalizing Sudoku Grab, my first app ever, published in 2009. The plan involves updating the code, upgrading to ARC, simplifying the menu system, accommodating iOS7, and supporting 4-inch display sizes. Future updates may include iCloud syncing features for universal access to puzzles. This endeavor also gives me an excuse to switch to an iPhone5s!

Version 2 of SudokuGrab released - We've updated SudokuGrab with some major enhancements including iCloud syncing for your puzzles and support for iPads. There are a few bugs we're aware of and we're actively working to fix them in the coming weeks, with a new version already submitted to the app store.

How does it all work? - In this blog, I explain the process behind my Sudoku Grab app, a solution that uses basic image processing techniques to recognize Sudoku puzzles. This is done by locating the puzzle in an image, turning it back into a square form, segmenting it to find potential numbers, and lastly, recognizing those numbers. This involves simple thresholding techniques, blob extraction algorithm, perspective transform, and a Neural Network for Optical Character Recognition (OCR) to recognize digits from the photograph. I conclude by mentioning the potential for multiple enhancements to this process.

25000 copies downloaded! - I'm thrilled to announce that Sudoku Grab has reached 25000 downloads! As a token of gratitude, the app will be available for free until the 25th June. A huge thank you to everyone who has purchased the app and for all the valuable feedback.
