Optimizing algorithm for categorizing pictures of Magic the Gathering Cards by type?

I'm making a piece of software that is able to recognize Magic the Gathering Cards from a picture or the actual camera. The codebase scans for rectangular shapes (cards) in an image and calculates 64bit perceptual hashes for them, which get compared…
