I'm looking to integrate OCR and ICR recognition functionality into a business app we're building to scan forms and other such documents. I've searched for hours and come up with Abbyy, IRIS and another few companies that market their SDKs with 4 figure prices. Do you know of any OCR/ICR engines that are free or affordable?
