Face recognition in images and video with Python
A bit unrelated but I'm in a need for some sort of cat deterrent that will spray water at all cats except mine. Also it would be nice if humans were exempted as well.I haven't done the legwork myself yet, but would this be an appropriate project to check out for this? 
(As for identifying my cat I've been thinking about alternative solutions such as rfid necklace or something but it is quickly getting past 'quick hack').
