// .NAME vtkImageIslandRemoval2D - Removes small clusters in masks.
// .SECTION Description
// vtkImageIslandRemoval2D computes the area of separate islands in
// a mask image. It removes any island that has less than AreaThreshold
// pixels. Output has the same ScalarType as input. It generates
// the whole 2D output image for any output request.
