Detailed Description

Filters that operate on pixel neighborhoods.

vtkImageSpatialAlgorithm is a super class for filters that operate on an input neighborhood for each output pixel. It handles even sized neighborhoods, but their can be a half pixel shift associated with processing. This superclass has some logic for handling boundaries. It can split regions into boundary and non-boundary pieces and call different execute methods.
