  its look like a fft problem...
  i guess you should take 2d fft of an image
  you can do that by fft2 command.
  
  But as i remember, if im not wrong there must be some other commands for spesific applications.

  thanks...
  I've tried taking the FFT using fft2 but that doesn't give me d frequency vs co ordinates plot. is there another step after fft2 to get dat?

  Hi All,
  
  I'm having the same problem. I have an image for which I have transformed using the fft2 method in matlab. Now I want to display this transformed image in spatial frequency coordinate system. How do I it? I mean how do I get the spatial frequency?
  
  Thanks in advance!
