See attached photos for reference.
I tried watershedding, it breaks apart the main body and doesn't even touch the part I want disconnected!
morphology is no good, the holes in the main body easily break in two before the edges I want disconnected come off.
imfill doesn't solve this, it fills the hole between the two trouble areas as well as the holes in the main body.
I have thousands of similar photos, so I need to come up with something robust.
I'd appreciate any help I could get!
