[Insight-users] How to know what parameters of a filter need to be set?

[Roman Grothausmann]

Dear mailing list members,


Although I like and value ITK very much there's a problem I've 
encountered a few times now: How do I find out what parameters of a 
filter have to be set?
An example: I need some kind of closing filter. So I search in 
http://www.itk.org/Doxygen/html/classes.html for close/closing and find 
quite a few filters.
Not knowing which one's the right for my case I try to find more 
information than the "Detailed Description" of each filter. If there's 
no description in the  ItkSoftwareGuide and/or the insight-journal I've 
no clue where to look else except the source which is very hard to 
understand quickly.
Looking at the Detailed Description of 
ClosingByReconstructionImageFilter only PreserveIntensities is mentioned.
Although mentioned there I couldn't find any filter called 
ErosionByReconstruction, only ReconstructionByErosionImageFilter. Is 
that the same?
I know Dilation needs a structuring element. So I have to choose its 
shape and its size, but the list of "Public Member Functions" of 
ClosingByReconstructionImageFilter is huge.
How do I know which are the important ones that need to be specified?

Any help is very much appreciated
Roman
