GVF Curve-skeleton extraction (Brun and Dreossi, 2010)

Computes the curve-skeleton of a binary 3D volume with the Gradient Vector Flow (GVF) method proposed by Brun and Dreossi (2010)

Computes the curve-skeleton of a binary 3D volume with the algorithm proposed in "F. Brun and D. Dreossi. Efficient curve-skeleton computation for the analysis of biomedical 3D images (2010) Biomedical Sciences Instrumentation, 46, pp. 475-480".

Code is delivered as a MEX C++ file and a wrapper .m function. A demo.m is also included (the demo requires R2018b Image Processing Toolbox only for visualization purposes).

Code has been tested with Microsoft Compiler under Windows and with g++under Linux. It is strongly suggested to compile the MEX file with a compiler supporting OpenMP, i.e. something like:

mex COMPFLAGS="$COMPFLAGS -O2 -openmp" GVFSkel_mex.cpp

otherwise just

mex GVFSkel_mex.cpp

and then run demo.m.
