[Insight-users] Grayscale Morphology

[Neal R. Harvey]

Can anyone direct me to some documents that describe how to use ITK's 
grayscale morphological operators?
I am assuming that itk::GrayscaleFunctionErodeImageFilter and 
GrayscaleFunctionDilateImageFilter and the operators I
am after. I want to perform morphological operations with greyscale 
(function) structuring elements that I have defined myself.
For example, I would like to implement a grayscale hit-or-miss filter 
that uses, for its "hit" and "miss" structuring elements,
examples of target and background extracted from images. I can't find a 
complete document that describes how to do this.
I was able to find an incomplete 4-page document entitled "Consolidated 
Morphology"
(http://www.insight-journal.org/browse/publication/124) but this was far 
from complete and didn't provide all the necessary information
that I would need to proceed.

Thanks and regards

Harve
