Hello Paola,


I´m sorry to bother again but I wanted to ask you something about the

Yes exactly. The citation is in the website:
http://fiji.sc/Skeletonize3D#Related_work

That behavior is intended. Since it is a thinning algorithm, the extremes
of the objects are eroded.

There's no problem. There are many skeletonization methods. You should find
the one that fits your requirements better. Have a look at this site about
different algorithms:
