[Insight-users] why use 3D watershed segmentation is very slow?

[Sergio Vera]

Hi there

The first check is to make sure you are using a release version of ITK
libraries.
Debug versions are several times slower (6-10 times in my experience)
Once this is checked, we can start looking at your parameters.
