I would like to ask for suggestions on how to obtain the thickness of the edges in a given input image

Sample image:

Suggestions on how to proceed will be really helpful.

In the end, I would like to obtain the centerline skeleton and find the thickness (/radius measure similar to maximal inscribed sphere radius for 3D) of each edge/branch.

Have you tried to use [VMTK](https://github.com/vmtk/vmtk) for this? SlicerVMTK’s centerline extraction module may give you this information directly.

If VMTK does not work on your data then you can do what is described in this post: [How to analyze the thickness of the model](https://discourse.slicer.org/t/how-to-analyze-the-thickness-of-the-model/2735)

@lassoan Thanks for the response. Yes, I could successfully obtain the thickness using Fiji. I will  
check VMTK, I wasn’t sure about how the thickness is computed for 2D in VMTK .
