Dear Hanna:

There is a Particle Counter plugin that might help.
http://rsb.info.nih.gov/ij/plugins/track/objects.html

but it goes a bit slow and doesn't do surfaces, so I'm working on making it a bit more 3D. Watch this space!
Or, check it out at github

Subject: 3D shape descriptors

Dear all,

I am new to image j. I need to somehow characterize shape of particles
segmented from 3D image stacks. Unfortunately I can't find any suitable
plugin and I don't have a knowledge to write one myself. I would be very
grateful if someone could suggest me any plugin or a way to calculate shape
descriptors such as roundness or circularity for image stacks.

Best regards,
Hanna
