Answer 2

That's a difficult question.

You should research computer vision.

I would think the method would be something like:

• Find edges (just image processsing)
• Trace shapes (not sure how to go about doing that)
• Pass to neural network for classification.

Of course, designing and training the network is not exactly a simple operation..
