parallel 3D binary skeleton DirectionalSkeletonizer Usage: skelpar3d in.pgm algorithm nsteps [inhibit] out.pgm
Description: Parallel 3D binary thinning or skeleton. The parameter nsteps gives, if positive, the number of parallel thinning steps to be processed. If the value given for nsteps equals -1, the thinning is continued until stability.
The parameter algorithm is a numerical code indicating which method will be used for the thinning. The possible choices are:
- 0: Palagyi (curvilinear, 6-subiterations directional, 1998)
- 1: Palagyi (curvilinear, sequential, 2006)
- 2: Palagyi (surface, parallel directional, 2002)
- 3: Palagyi (surface, fully parallel, 2008)

If the parameter inhibit is given and is a binary image name, then the points of this image will be left unchanged.
