Windows 7 OCR API

Question

I have been reviewing replacements for the Office 2007 MODI OCR (OneNote\'s 2010 solution has lesser quality/results than 2007 :-( ). I notice that Windows 7 contains an OCR lib

Answer 1

Try TessNet, using the suggestions I made to the Poster in this post (enlarge image, use separate process):
c# OCR can't recognize digits (tesseract 2)

Answer 2

1. Tessnet OCR is a good solution, but pretty old (last release from 2009). There are couple of very good free OCR solutions available for .NET:
2. Asprise C# OCR SDK. Very good and fast one.
3. Microsoft Research Project Hawaii Web-based (cloud) OCR solution with full docs and samples (discontinued 2013)
4. Bing OCR Web based (cloud) OCR replacement for above. (discontinued March 2014)

Answer 3

I was exploring the windows 7 dlls and I found 3 libraries that might be useful: thocr.psp.dll ,xocr3.psp.dll, and ximage3b.dll. In this website and other similar websites I found out that ximage3b is a Windows system ocr engine. I have been looking for documentation online but I have not been succesful, but hey! at least I know that it's there, I will give you guys an update if I find out how to use it with C#/C/C++.
