Whenever an image has a sudden jump in frequency at some place like in salt and pepper noise, gaussian smoothing is used to blur the image by using the Gaussian Function.

It helps you to reduce the sudden spikes in an image but simultaneously cause loss of information.

Basically it is like an averaging filter whose kernel is formed by gaussian function.
