I have a issue with FFT method for translation, rotation and scalling in image registration. Can U explain me how and why i use FFT method to check if e.g rotated image is the same as original image (my project include that i HAVE to use FFT method). I would be very gratefull if someone show me a Matlab code of how it should work properly, because i really dont have any idea how to start this. Thanks for all replies.

Yea but this is goes automatically. I rather wanna to understand why does it happend. I know that i should calculate FFT from eg lena.png and rotated, scalling lena2.png. But what it comes next?
