Introduction to Filters

The SPIP Filter Module provides a comprehensive set of predefined spatial filters and tools for designing dedicated filters. You can use the various filters for getting nice presentations and robust measurements by noise reduction or to emphasize certain textures.

 

The filtering techniques implemented in the SPIP program are divided into these four groups:

 

The filters described here are all spatial filters while Fourier filtering (Frequency domain filtering) is part of the Fourier module and is described in the Fourier section.

 

For information on how to use the filter module the following sections are included:
