From image .png to 'skeleton' structure

[Giorgia]

Hello!
I’m trying to get the ‘skeleton’ of the image I’m importing.
The problem is that I’m stuck and can’t get a line that intersects the points in question. I’m trying to solve it with the Pufferfish plugin, but I can’t find the right component.

I would like to get something like this (following photo, blue line)…Could you help me?
Thank you!

Ok here a little code that uses 95 % of code from TAW. This code is doing thinning of an image https://homepages.inf.ed.ac.uk/rbf/HIPR2/thin.htm [image] [image] You must have a good black and white image. If not … [image] image_thinner_LEGACY.gh (7.2 KB)

Thank you Laurent!
I have a problem: am trying to install the Fennec plugin, but all I get is the icon shown in the photo. I placed the .gha file in C:\Program Files\Rhino 7\Plug-ins\Grasshopper\Components and the .ghpy files in C:\Users\gprosperi\AppData\Roaming\Grasshopper\Libraries\Fennec.
I have 7.28.23058 version installed.
