// .NAME vtkImageSpatialFilter - Filters that operate on pixel neighborhoods.
|
|
// .SECTION Description
|
|
// vtkImageSpatialFilter 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.
