SPATIAL FILTERING OF IMAGE

To perform spatial filtering on a 2-D image using MATLAB.

Spatial filtering term is the filtering operations that are performed directly on the pixels
of an image. The process consists simply of moving the filter mask from point to point in an
image. At each point let (x,y), the response of the filter at that point is calculated using a
predefined relationship. The spatial filtering can be mainly of two types, Linear spatial filtering
and Non-linear spatial filtering.
