Let's say I have an original image and it goes through a random affine transformation, what is the best way to figure out how much affine transformation was applied?

I already have a method of determining if the new image is closely related to the original one by doing a SURF comparison and FLANN KNN matches, just looking for a way to do find that affine transformation matrix.
