Tesseract OCR. Or http://en.wikipedia.org/wiki/Tesseract_%28software%29
There's a GUI for it for Apple Mac OS X.
Hi, I have photographs taken from my iphone of labels that I want to use OCR on...any recommendations? I can't get Adobe Acrobat Pro 9 to work and have tried ScanVue, but it won't do OCR on an existing image.
