How to Inverse Fourier Transform this?

Hey Everyone,

I have the fourier transform of an image using this code:

af = fft2(noisyImage);
saf = fftshift(af);
Img_FT = mat2gray(log(1+abs(saf)));

How do I inverse this Fourier Transform of Img_FT in this situation.

I assume you want to find Inverse Fourier transform of an image.

You may try this line of code

imagesc(ifft2(Img_FT));

ifft2 is used to return 2D inverse Fast Fourier transform of a matrix.
