Looking for C++ OCR library

Question

I am looking for an OCR library (commercial or free) that I can use of my C++ project.

My project is mobile-based, so the library cannot depend on .Net or any framework like that.

Can you recommend any?

Answer 1

If open source is acceptable, you might look at gocr which provides a library... Looking at my own link I see reports that libgocr is dead. I don't know what to make of that.

Sorry.

Answer 2

Tesseract OCR - it's an open source (Apache license) OCR engine.

Answer 3

I know some projects for your request:

Cuneiform ( http://www.cuneiform.ru/eng/index.html ) - best recognition in opensource world

Answer 4

If you're ok with calling an external server for doing OCR, try WiseTrend - http://www.wisetrend.com/wisetrend_ocr_cloud.shtml - it's a REST API for OCR, based on the ABBYY engine (great recognition quality specifically for low-quality images taken with mobile cameras)
