Dilation and erosion are image processing functions used to "grow" and
"shrink" objects and boundaries.  They are part of a group of image
operators based on the theory of mathematical morphology.  Overall,
they are very extremely useful for shape/size analysis on images.

Yes, they should certainly be part of any image processing toolbox for
Python.  Here is a link for a commercial math. morphology toolbox for
matlab: http://www.mmorph.com
