Periodic noise removing filter

Goal

In this tutorial you will learn:

  • how to remove periodic noise in the Fourier domain

Theory

Removes periodic noise, background and interferences in the Fourier domain. Useful for latent fingerprints, capture artifacts and electromagnetic interferences in videos

Result

Below you can see the real world image with periodic noise Original image with periodic noise

Below you can see the restoration result. Filterred image

You can also find a quick video demonstration YouTube
