Dear ImageJ users and developers

I have actively searched for a tool that classifies a binary skeleton according to Strahler (used in hidrology). I would like to estimate the number of branches for each order of a branching structure (gorgonian coral). Does anyone have a clue on how can I do it?
I have managed to estimate the number of terminal branches using Gabriel Landini's plugins:

skeleton -> connectivity -> three duplicates -> dup1 threshold 2:2 (terminal branches) -> dup2 threshold 3:3 (segments of branches or branches) -> dup3 threshold 4:4 (bifurcations) -> testim Process:Image Calculator im1=dup1 Operation OR im2=dup2 -> morhology plugin BinaryReconstruct mask=testim seed=dup1

this works for the order 1 branches but I haven´t figured out how to manage to separate the other orders. My scripting skills are very limited.

Any ideas are welcome

Thanks for your time

Joao
