Removing periodic noise from an image using notch filter

This program denoise an image corrupted by periodic noise using a band reject filter(notch filter).

One of the applications of band reject filtering is for noise removal in applications where the general location of the noise component in the frequency domain is approximately known.This program denoise an image corrupted by periodic noise that can be approximated as two-dimensional sinusoidal functions using a band reject filters.You can adjust the radius of the filter mask to apply it for a different image.
