Zernike moments will compare size invariant, rotational invariant, and if memory serves, mirror invariant and give you a fuzzy value to determine if they match.
We used to reduce the image first, cut it to 1/4 or 1/10 or whatever pixels make sense based off original sizes. You don't have to check 10+ million pixels in a high res image -- often a few hundred or a couple thousand will tell you enough and its much, much faster.
These 2 things solved this type of problem for us, but the z-moments are significant amount of coding.
