So I’m not finding a way to identify objects that are simply the binary mask of other objects from which the outlines have been subtracted.
I’ve found quite sourprising that I can’t find objects that are completly white in a completly black background. All objects are separated by the completly black boundaries. In same places there are few objects and in others quite a lot ot them. That may be turning the smoothing a litle bit crazy but I set it to 0 or 1 and had no luck. I tried every possible thresholding but didn’t help much.
