Camera Integration

One of the coolest features is the ability to capture and instantly solve sudoku puzzles from newspapers, magazines, etc.

ML and AR

Camera integration requires state of the art image processing and machine learning to detect the puzzle, determine the puzzle orientation, fix for skew and noise, identify the grid, identify the digits, solve the puzzle and display the results. All of this is achieved through custom, native C++ code running on the device in real-time.
