Two dimensional discrete Fourier transform units

Homework Statement


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?



Homework Equations





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?
