Morphological techniques

Hi guys, I've been fiddling around with the library for some time now. And, its really brilliant to have efficient implementations of a bunch of algorithms in 1 place and seeing just a simple function call take care of the task. I am really excited about being a part of this community and have been pretty fascinated by morphological techniques in particular. I would really want to contribute something in this direction. Can someone please point me to possible bugs or algorithms in this field that need implementations ? Thanks, Chintak
