Equivalent of watershed for cutting connected components of an image of particles?

[Juan Nunez-Iglesias]

You could do a morphology.closing. That's kind of why it's called that. =D




Obviously you don't want to run it on the whole image, but I presume you're doing classification on the regionprops objects, so you could do the closing on each object individually.
