Chen,
You can find most, if not all, of the morphological operations
provided by ITK here:
http://www.itk.org/Doxygen36/html/group__MathematicalMorphologyImageFilters.html
You might also want to check out InsightJournal, as I believe it had a
number of papers related to image morphology.
hope this helps
