Playing card recognition with webrtc, websockets and opencv

This is a webrtc, websockets and opencv experiment based on an experiment during a athega hackday.

How does it work?

Frames are captured from the web camera via webrtc and sent to the server over websockets. On the server the frames are processed with opencv and a json response is sent back to the client.

Sample json response:

  {
    "cards": {
      0: {
          "color": "hearts"
          "value": "king"
      }
      1: {
          "color": "spades"
          "value": "ace"
      }
    }
  }

Running it

Make sure the dependencies are met.

• OpenCV with python bindings (I'm using the trunk version)
• Tornado
• PIL

Run with python server.py and browse to http://localhost:8888
