You are delving into optical character recognition -- OCR. Although good
results have been achieved, the problem is not completely solved despite
decades of work. You have a lot of reading to do. I wish you luck.

You might find software at http://www.simpleocr.com/ interesting.

I doubt that this is a task for Matlab.
