The 2D Fourier Transform

Applying the Fourier Transform over images using TensorFlow. – Jun 9, 2021

Similarly to my previous post, I decided to publish here an assignment that was submitted to a Computer Vision class. Its goal is to apply the Discrete Fourier Transform over images using Python programming language and assess its results. Firstly, I implement low, high and band-pass circular filters in the frequency domain for 2D signals. Secondly, I present two examples: (a) a visualization of the frequency spectrum the when the original signal is rotated; and (b) an image compression strategy based on Fourier Transform.
