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.
Refer to the link below for any clarifications.
