Maybe you could use ndimage.morphology.grey_closing, I cant find a
code example using it, but the idea is similar to the examples
featured in this page:
http://www.mmorph.com/pymorph/morph/morph/mmclose.html

The "close hole" operator is probably closer to what you intended:
http://www.mmorph.com/pymorph/morph/morph/mmclohole.html

I am not sure whether this operator is implemented in the free version
of pymorph, maybe you should give it a try:

Hope this helps.
