Detailed Description

template<class TInputImage, class TOutputImage, class TKernel>
class itk::ObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >

Base class for the morphological operations being applied to isolated objects in an image.

This class provides the infrastructure to support of morphological operations being applied to images in which the foreground and background intensities are fixed. This filter operates significantly faster than itkBinaryMorhologicalImageFilters; however itkBinaryMorhologicalImageFilters preserve background pixels based on values of neighboring background pixels - potentially important during erosion.

The "kernel" specified represents a morphology structuring element. The structuring element is a small Neighborhood with values indicating an element is "on" (value > 0) or "off" (value <=0). Morphological operations are defined by placing the structuring element over a pixel, and calculating a nonlinear function (min, max) over the pixels of the image that are under pixels in the structuring element that are "on". The result of this calculation is the value of the pixel in the output image. Under most circumstances, the "center pixel" of the structuring element -- or structuring element pixel over the input pixel under consideration -- is prescribed to be "on". This is not a strict requirement but the subclasses of this filter are not guarenteed to produce the correct result if the "center pixel" is not part of the structuring element.

Subclasses of this class can define their own operations by simply providing their own Evaluate() protected member functions - one that operates using a smart neighborhood operator for edge faces and one that operates using a standard neighboorhood operator..
