OpenCV Demos

Character Recognition

Environment Setup

• Download & Install OpenCV 3.0.0
  
• Download & Install EmguCV, the OpenCV wrapper libs for .NET, from here.
  
• Set a system-wide variable pointing to the EmguCV install dir, for example
  
  EMGU_ROOT=C:\bin\Emgu
  
  You can do this via System Preferences/Advanced Settings
  
  
• Expand the variable PATH, which is in the same settings window, with
  
  %EMGU_ROOT%\bin\x64
  
  This entry is needed because the app will automatically search for cvextern.dll located in this directory.
  
  
• Open the solution file and start the app (Notice: this is an x64 app)
  
• Load one of the available images from the Assets folder (these are simple invoice documents)
  
• Click on Analyze and wait for the OCR-task to complete.
  

Example

There's a second app which is currently in development. No real OCR there, only a few tests with loading images and (de)serializing them.
