13.2: The Fast Fourier Transform (FFT) - Engineering LibreTexts

WebJan 8, 2013 · Explanation. The Fourier Transform will decompose an image into its sinus and cosines components. 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.
