QGis Image Classification Tutorial: 2.3- The spatial filters The spatial filters represent another method of digital processing used for the enhancement of an image. These filters are designed to bring out or remove specific features of an image based on their spatial frequency. The spatial frequency is related to the concept of texture.

Issues with Spatial Autocorrelation in GIS. In general, spatial autocorrelation has a lot of utility for GIS users as it provides an indication of clear spatial correlation for given data.

Filters in spatial domain: Spatial filters used different masks (kemels, templates or windows). There is a one-to-one correspondence between linear spatial filters and filters in frequency domains. Spatial filters can be used for linear and nonlinear filtering.
Filtering classified output. Available with Spatial Analyst license. This filtering process removes isolated pixels, or noise, from the classification output.
Spatial Filtering means playing with pixel and its neighborhood pixels. A filter mask is moved in an image from point to point. At each point of an image, the response of the mask is calculated by the pre-defined relationship. There are lots of filters available in image processing but knowing every filter and its specialty is really important.
