Two-Dimensional Fourier Transform

Fourier transform can be generalized to higher dimensions. For example, many signals $f(x,y)$ are functions of 2D space defined over an x-y plane. Two-dimensional Fourier transform also has four different forms depending on whether the 2D signal is periodic and discrete.
