Detailed Description

parallel grayscale homotopic thinning

Usage: hthinpar in.pgm {imcond.pgm|null} connex niter out.pgm

Description: Parallel grayscale homotopic thinning (refs. [BEC97, CBB01]). The parameter connex gives the connectivity used for the minima; possible choices are 4, 8 in 2D and 6, 26 in 3D. Let F be the function corresponding to the input image in.pgm. Let G be the function corresponding to the input image imcond.pgm, or the null function if the keyword null is used.

If niter is set to -1, then the operator iterates until stability.
