Hi,

In ImageJ, one can select watershedding to break up connected regions of particles.  Are there any examples of using watershed in this capacity in scikit image?   All of the examples I see seem to use watershedding to do segmentation, not to break connected particles in an already-segmented black and white image.  

Also, is there a straightforward way to remove particles on a the edge of an image?  Sorry, googling is failing me, but I know this is possible.

Thanks
