Smooth the filter using a Gaussian window: Log-magnitude plot of the frequency spectrum of the filters: … WebGaussian Smoothing. Common Names: 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 …
