[Insight-users] Fuzzy implementation

[Luis Ibanez]

Hi Alex,


You are probably looking at the class

            SimpleFuzzyConnectednessImageFilterBase

that is the base class for the FuzzyConnectedness filters.

This class defines most of the API and delegates some of
the specific implementation to is subclasses.


The hierarchy looks like:


    itk::ImageToImageFilter
       |
       +---itk::SimpleFuzzyConnectednessImageFilterBase
       |       |
       |       +--- itk::SimpleFuzzyConnectednessRGBImageFilter
       |       |
       |       +--- itk::SimpleFuzzyConnectednessScalarImageFilter
       |
       +--- itk::VectorFuzzyConnectednessImageFilter



The method FuzzyAffinity() is virtual and it is intended to be
overriden by implementatinos in the derived classes.


You will find implementations of the FuzzyAffinity() method in
the following files:


	itkSimpleFuzzyConnectednessRGBImageFilter.txx
	itkSimpleFuzzyConnectednessScalarImageFilter.txx
	itkVectorFuzzyConnectednessImageFilter.txx



Regards,


    Luis
