Periodic noise is the spatial kind of noise that cannot be eliminated in the spatial domain. To remove this noise we have to work in the frequency domain. So how to remove this periodic noise? Here is the code for removing periodic noise. Since the filter response H(u,v) is not centered we can't use high pass filters such as Ideal, Butterworth, Gaussian. To remove this noise we require a filter who has H(u,v) having two square dots near the center.
