Best approach for identifying Set cards

I have some basic experience with OpenCV after reading a few books. I want to write a program that identifies cards from the game Set from an image like this (and eventually from live video):

Set cards

I'm wondering what the best approach would be.

  • Should I train nine objects (three different shapes with three different shadings) and find those in the image?
  • Should I use edge detection and try to identify the shapes that way?
  • Is there some other approach I should use?
