Well, the object is independent of centroid or min/max or overlap. isn' it? that just depends on the particular aim of each user. matching nearest neighbors remains a useful object to have...
That's why [#labelling] also outputs a version of the incoming grid in which the "1" regions have all been flood-filled with distinct integers (numbered from 2 upwards ; it can go well beyond 255 if needed).
I am not entirely sure what you mean by this...
best,
J
However, I don't know any easy way to compare two images for overlap (in number of pixels), and I have not tried this yet (nor any other form of tracking of the found regions).
