skeleton in 3D

Distance transform oriented code for 3d skeletonization.

Description

Implements parameter controlled skeleton -ization of 3d objects.

The core of the 10 lines code implements a simple method based on distance transform (rather than thinning based methods).

The method is sensitive to the value of the user defined Thinness Parameter (TP).

An alternative approach to 3D skeletonization that use the gradient and divergence of the distance transform is also given

Respected sir,
I kindly request u to mail me a mini dsp project with source code for the completion of my degree .kindly obligue.
tanking you

[Luigi Rosa]

Very useful routine

Dear Gianni Schena;
Do you have code of skeletonization for 3D bronche data sets-extract the central line- ?

[huss chawa]

ok

[EL OIRRAK ahmd]

good work but i d'ont

Needs an update/improvement. The comments could be vastly improved. Better, more descriptive variable names should be chosen. The links in the description no longer work.

The code rejects fspecial3 function and I cant proceed from here.

[Ben]

Both reference links are died. How about this program?? :(

Anyone know the idea on how to tune the parameter?

[David]

the performance highly correlated to the tuning parameters, and also there is no mechanism applied to check the connectivity of the centrelines.
