Gaussian Smoothing
Brief Description
The Gaussian smoothing operator is a 2-D convolution operator that is used to blur' images and remove detail and noise. In this sense it is similar to the mean filter, but it uses a different kernel that represents the shape of a Gaussian ( bell-shaped') hump. This kernel has some special properties which are detailed below.
