Tessnet2 Init-Method crashes with certain tessdata path

Question

I\'m using the Tessnet2 assembly (which uses Tesseract) to do OCR. Unfortunately the programm crashes without any exception after I call the init method:

tessne         


        

Answer 1

Try the path:
     @"D:\Test\Tessdata"

Answer 2

The problem is that if you have Tesseract installed there is an environment variable set ( TESSDATA_PREFIX )which contains the path of the tessdata. To use your own path it is necessary to uninstall Tesseract and delete the environment variable.
