GUIDANCE FOR IMAGE PROCESSING WITH ARDUINO

Hello, I want to capture an image, store it. And after every fixed period of time (lets say 1 minute) I would like to capture an image again(will not save this one) and compare it with the previous saved photo and generate result if they match or not. Can this be done with arduino. If yes how? If not in what other ways can I make this work?

WHY DOE YOU SCREAMMMMMM!!!!?????? Please edit the title.

And basically no, image processing isn't something that's easily done on a micro controller.
