WebThe Gaussian smoothing operator is a 2-D convolution operatorthat 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 kernelthat represents the shape of a Gaussian (`bell-shaped') hump. This kernel has some special properties which are detailed below. How It Works WebGaussian filters are frequently applied in image processing, e.g. for bluring low-pass filtering noise suppression construction of Gaussian pyramids for scaling Moreover, derivatives of the Gaussian filter can be applied to perform noise reduction and edge detection in one step.
