Detailed Description

parallel 2D or 3D binary skeleton, ultimate, asymmetric

Usage: skel_AMK in.pgm nsteps [inhibit] out.pgm

Description: Parallel 2D or 3D binary ultimate, asymmetric 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.

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

The algorithm used here is indeed a variant of alg. NK2 described in [BC08], which allows for an arbitrary (and even null) constraint set.

Warning: The object must not have any point on the frame of the image.
