Detailed Description

parallel 2D binary curvilinear skeleton

Usage: skel_AK2 in.pgm nsteps [inhibit] out.pgm

Description: Parallel 2D binary thinning or curvilinear 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.

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