In the segment editor, is it possible to apply grow from seeds not only to the master volume, but directly onto a thresholded segment?
You can export the segment to a labelmap volume and use that as master volume.
What is your use case? What problem would you like to solve?
I’m looking at a fractured humerus and I would like to generate a workflow that semi-automatically recognizes the different fracture pieces and separates them as distinct segments. They are visually very island-like but they still have connections to the larger bone in many cases, which makes the ‘Grow from seeds’ functionality fail for me
That question is already discussed in this topic, let’s just continue the discussion there.
