%PROGRAMFILES%\Common Files\microsoft shared\OCR\7.0\xocr3.psp。 DLL

- Tessnet OCR是一个很好的解决方案,但是(从2009年最后一个版本)很老。有几个非常优秀的免费OCR解决方案,可用于.NET:
- 的 Asprise C#OCR SDK 。非常好,速度快的。

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 library once you install the optional tiff filter
The OCR component gets installed to
%programfiles%\Common Files\microsoft shared\OCR\7.0\xocr3.psp.dll
but I don't see any API for it?
Does anyone see how this can be interfaced preferably in C#?
ANSWER: Found the soluation, once the optional tiff ifilter win7 feature is installed, i can then get a textoutput of a screenshot using the code/exe on http://www.codeproject.com/KB/cs/IFilter.aspx. Also if add the same [HKEY_CLASSES_ROOT.tiff\PersistentHandler] for .png and .jpg then OCR also works for jpg and png's.
- 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:
- Asprise C# OCR SDK. Very good and fast one.
- Microsoft Research Project Hawaii
Web-based (cloud) OCR solution with full docs and samples(discontinued 2013) - Bing OCR
Web based (cloud) OCR replacement for above.(discontinued March 2014)
