public class SoSigmaFilterProcessing
extends SoImageVizEngine

SoSigmaFilterProcessing engine The SoSigmaFilterProcessing3d engine computes a local mean, around the central voxel.

For an introduction to image filters, see section Images Filters.

This engine computes a local mean, around the central voxel, of neighbor's voxel values. Voxel values far from the central voxel intensity are excluded using a user threshold . Only voxels verifying the following formula are kept for computation:

A user population threshold allows switching between the above formula and a classical neighbor mean formula. This allows avoiding considering low populated neighborhoods for computation.
