Hi all,
I have tried all the suggestions i got and was not completely satisfied so therefore I went ahead and created a greyscale skeleton transform plugin for imageJ
The code and files can be found at
https://github.com/Karivtan/Grey_skeletonIf anyone wants to try or has suggestions I'll be glad to hear them.
The plugin is based on the following papers
Kundu et al. 1991, A parallel graytone thinning algorithm
Zhang & Suen. 1984, A fast Parallel algorhitm for thinning digital patterns
