Homework Help: Two dimensional discrete Fourier transform units

  1. Jun 3, 2013 #1
    1. The problem statement, all variables and given/known data
    I have am doing a two dimensional discrete Fourier transform on an image (using MATLAB). What are the units associated with each pixel of the image in the frequency domain?

    2. Relevant equations

    3. The attempt at a solution
    I thought that the frequency should be (+/-number of pixels away from the DC component)/(pixel width, in meters). This would give units of 1/length, which would make sense. Is this correct?
