Removing noise from an image using the Fourier Transform of that image

I am trying to remove noise from an image. The image itself has a specific pattern but there is a lot of noise on it. I am trying extract the pattern.

I have the target image. I am posting the result from taking the fourier transform of both of the images. I would aprreciate if you could help and guide me with solving this problem

fft2 of the input image:

fft2 of the target image:
