Optical character recognition on the iPhone

Question

Is it possible on an iPhone app to take a picture and extract an string from the picture? We'd like to make our app to look for a serial number on a database (very long number) without the user having to type it.

Is there any Cocoa/Objective-C API for this or any C/C++ library that can be used in an iPhone app?

Thanks in advance!

Answer 1

You can have a look at the tesseract-ocr project. It's not actually made to use on an iPhone but I believe others have made great use of it on the iPhone.

Here is a demo that makes use of the tesseract ocr engine.
