2D Frequency Plot?

I need some help with displaying the frequency components of an image in
the x and y directions. I know how to display the results from the 1D
case

Fk = k x fs / N

where k is the bin number, fs is the sampling number and N is the number
of points in FFT.

I would like to perform a 2D fft on an image and then have a mesh plot
in terms of the x frequency and y frequency. If anyone can help send me
an email.

Thanks,
Joe
