Thread Subject:
adjacent vs overlapping blobs

Subject: adjacent vs overlapping blobs

I would like to differentiate between two adjacent,
circular blobs and those that are overlapping.

Using the example in the help file for bwdist I see that
if the blobs overlap there tends to be a line connecting
the centers.
When blobs are just touching, but not overlapping (try
changing the 1.4 in the line to 1)
radius = dist/2 * 1.4;
Here, there is no line between the centers.
Is there any way to algorithmically determine if such a
line exists?

Thanks!
Daphne
