    Hi,
    can someone please tell me how to get the spatial frequency of the image in MATLAB. I want to be able to plot the frequency against the x or y co ordinates of the image matrix.
    Please help.

    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!
