Optical Character Recognition

OCR is the ability to scan a document (or grab a PDF file) and run an OCR program on it and it will generate, based on optical recognition and approximation, an editable text file. For an idea about OCR see http://www.students.cs.uu.nl/people/mjkammer/Work/intro_2_OCR.html

Current Status of Arabic OCR software

I (MuhammadAlkarouri) know of no actually working Arabic OCR software that is open source. Any additions are certainly welcome.
