Region labeling algorithm that will tolerate gaps?

The Matlab 5.0 image processing toolbox comes with a nice
connected-components labeling program called 'bwlabel'. I'm looking for
something that is like that, except that I would like it to tolerate gaps.
For example, in a binary image like this:

###########
#ooo##oooo#
#ooo##oooo#
#ooooooooo#
#ooo##oooo#
#ooo##oooo#
###########

I would like the two clumps of o's to be labeled as two separate regions,
rather than one region separated by a thin line. I'm guessing there might be
a way of doing this by setting some sort of minimum threshold on what the
labeling algorithm considers to be a connection.

Does anyone by any chance have such a thing already? Or can someone point me
to literature that discusses how this could be implemented?
