Sudoku Camera is an experimental project combining webcam sudoku C++ code from the Webcam Sudoku project and android camera Java code from the android docs and the android-ocr project. This works after a fashion, but not well enough to be released as a useable app.
The source files from the Webcam Sudoku project, although allegedly open source, do not contain any licence information. They have been tidied using Artistic Style, and the over wide comments tidied using Emacs.
