Detailed Description

homotopic skeleton of a 2d or 3d binary image with dynamic detection of end points

Usage: skelend in.pgm connex [n] out.pgm

Description: Homotopic skeletonization by iterative removal of simple, non-end points. Breadth-first strategy. During the first n iterations (default 0), the end points are removed as well. If n = -1, the end points are always removed.

Types supported: byte 2d, byte 3d

Category: topobin

Warning:

This operator is very sensitive to small contour irregularities. See skelcurv for a more robust operator. Useful for reducing quasi-curvilinear objects.
