Hi all,
I have a 3d skeleton of which I want to calculate the number of branchpoints. Is it ok to use this code?
bp = bwmorph3(skel, 'branchpoints');
cc = bwconncomp(skel,18);
numberOfBranches = cc.NumObjects; % 1object = 1 branchpoint??
I attach an image of my 3d skeleton and of the branchpoints
Thanks in advance for any help!

Something does not look right. Specifically, the skeleton should be a line, and you do not seem to have any lines, just disconnected points.
Why don't you first detect the skeleton and display it, then manually count your branching points and then you can validate that the result of the branching points obtained with matlab is correct.

I would suggest that you do a maximum intensity projection into 2D, i.e.
data_2D = max(data_3D, [ ] ,3);
and then check the skeleton. In 2D you should have something standard like the ones shown here
Then you know if it is the data or the code that you are using
