C/C++/Objective-C text recognition library


Question

Does anyone know of any free/open-source text recognition libraries in C/C++/Objective-C? Basically something that can scan an image, and read out all of the plain text.

Accepted Answer

The most famous one is Tesseract OCR developed initially by Motorola and later become open source. It is also promoted by Google.

There are a few more, perhaps not as famous as Tesseract: http://en.wikipedia.org/wiki/OCRopus http://jocr.sourceforge.net/

Here is an interesting article on how to extract numbers from picture.

The author collects large number of samples to train his neural networks algorithm and I believe doing the image processing with OpenCV.
