parallel 3D binary surface, asymetric skeleton based on thin 2D isthmuses
Usage: skel_ASK3b in.pgm nsteps isthmus_persistence [inhibit] out.pgm
Description: Parallel 3D binary thinning or surface, asymetric skeleton based on thin 2D isthmuses. 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.
When a point x is detected as a 2D isthmus, a counter p(x) is associated to this point and initialized with value 1. This counter is incremented a each iteration as long as x is still an isthmus. At each iteration, the isthmuses x such that p(x) >= isthmus_persistence are stored as a constraint set (see also inhibit parameter).
If the parameter inhibit is given and is a binary image name, then the points of this image will be left unchanged.
