removing the values responsible on the scale, rotation, translation of an image in a DFT matrix

Hello everyone

I have coded a 2 dimensional DFT function that output a dft matrix of complex numbers.

I would like to know how can i remove the values responsible on the scaling, translation, and rotation of an image, so that when i have 2 images for example:

Image1

Image2 = Image1 rotated by 90degree

once we compare the DFT matrix of both images, we find that they're equal.
