FFT transforms for images [message #11509]

Hi,

I'd like to do some processing using a FFT transform. Basically all I
want to do is calculate the FFT
of an image, histogram equalize the power spectrum and then inverse the
FFT, producing what is in
effect an attentuated version of my image. I assume the built-in FFT
routine in 1D... does anybody have
any suggestions short of writing a 2D FFT.

thanks,

Michael
