Have a look at wiki[1] - I tried to keep there list of known implementation of tesseract-ocr.
There is also interesting paper from Poznań Supercomputing and Networking Center[2], where they document their experience with tesseract and its training.

Hello,

in our project, we would like to decide about using Tesseract for it or not. I would like to ask somebody who is successfully using Tesseract (or Ocropus combination) in any project. What kind of document are you using it on? Is your project successful? Do you think your project is successful in the view of your client?

Thanks for anybody who is willing to share some info.

Jakub

I was recently playing around with Wolfram Research's Mathematica [1].
While trying to figure out if it was possible to see the source for
some of their new Image Processing functions (sadly no I think, since
everything in Mathematica\9.0\SystemFiles\Kernel\SystemResources\Windows\ImageProcessing\
seems to be .mx rather than .m files), I stumbled upon the following:

C:\Program Files\Wolfram
Research\Mathematica\9.0\SystemFiles\Converters\Binaries\Windows-x86-64\tesseract.exe

C:\Program Files\Wolfram
Research\Mathematica\9.0\SystemFiles\Libraries\Windows\leptonlib.dll

and

C:\Program Files\Wolfram
Research\Mathematica\9.0\SystemFiles\Converters\Tesseract\tessdata\

(which contains 7 traineddata files)

Googling, I see that the TextRecognize function [2] is indeed
implemented using tesseract [3][4][5].

OT but fascinating for its use of various Mathematica and OpenCV image
processing operations see [6]. (One day I should try my own solution
using just leptonica).
