[Insight-users] Multiple seeds in FuzzyConnectedNess

[Luis Ibanez]

Hi Vincent,

Question 1:

The method SetObjectsSeed() for multiple seeds is only
available in the class VectorFuzzyConnectednessImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1VectorFuzzyConnectednessImageFilter.html

not in the SimpleFuzzyConnectednessScalarImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1SimpleFuzzyConnectednessScalarImageFilter.html

If you will, please feel free to add this as a
"feature request" in the Bug tracker.

Question 2:

The class SimpleFuzzyConnectednessScalarImageFilter does not
derives from the VectorFuzzyConnectednessImageFilter. Instead
it derives from the SimpleFuzzyConnectednessImageFilterBase, that
in turn derives from the ImageToImageFilter class.

The VectorFuzzyConnectednessImageFilter derives from ImageToImageFilter
and does not have any classes deriving from it.

You can easily verify this by looking at the corresponding
headers in

             Insight/Code/Algorithms



It is unclear why the class diagram is not being generated
by Doxygen for the SimpleFuzzyConnectednessScalarImageFilter.
There is an open bug logged regarding this issue, Bug #447:
