2D Frequency Plot?
Posted:

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
