In other words, it will transform an image from its spatial domain to its frequency domain. The idea is that any function may be approximated exactly with the sum of infinite sinus and cosines functions. The Fourier Transform is a way how to do this.

Websampled (X x Y in space, 1/MX x 1/NY in frequency) • In the CFT, if one function has compact support (i.e. it is space- or frequency-limited), the other must have ∞ support • Therefore, aliasing will occur with the DFT, either in space or frequency. If we want the DFT to closely approximate the CFT, • The Fast Fourier Transform (FFT)
