Detailed Description

homotopic thinning based on critical kernels

Usage: 3dskelck in.pgm mode niter [inhibit] out.pgm

Description:

Homotopic thinning of a 3d Khalimsky image. The maximum number of steps is given by niter. If the value given for niter equals -1, the thinning is continued until stability.

The parameter mode specifies the algorithm used for thinning. Possible choices are:

• 0: ultimate crucial thinning, symmetrical

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

Warning:

Input must be a complex with no point on the image border.
