We provide two exemples, on Highpass spatial and other Lowpass spatial filter in AboutPressCopyrightContact Non-linear spatial filtering With linear filtering the value at each grid position, G, is altered using a simple kernel as a weights matrix. With non-linear filtering kernels are not generally used. Instead the value at Gis determined by some procedure other than weighted averaging. In order to produce a clean Gaussian beam, a spatial filter is used to remove the unwanted multiple-order energy peaks and pass only the central maximum of the diffraction pattern (see illustration). Also, when a laser beam passes through a system, dust in the air or on optical components can disrupt the beam and create scattered light.

From Turvey & Pettorelli, 2014). 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. In this video we provide an animation of image processing spatial filtering.

Fundamentals of Spatial Filtering • Types of Spatial Filtering • 1) Point to point (pixel to pixel) operation (discussed so far) • 2) Mask based (Neighborhood) operations i) Operation with 3x3 filter (E.g. Mean, max, min, etc) ii) Correlation or Convolution • Linear vs Non-Linear Filter If the operation performed on the image pixels is linear, then the filter is called a linear spatial
