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.

And that's it, that's our DFT implementation. We can save it in a file, let's call dft.py. And so, this is the script that we'll run that. In order to see if it works well, we need to put an input signal. So before the code of the DFT, let's start using a particular signal. code for cryotherapy wart
