morph_skiz — Thinning of a region.
morph_skiz is obsolete and is only provided for
reasons of backward compatibility.
morph_skiz(Region : RegionSkiz : Iterations1, Iterations2 : )
morph_skiz first performs a sequential thinning
(thinning_seq) of the input region with the element 'l'
of the Golay alphabet. The number of iterations is determined by
the parameter Iterations1. Then a sequential thinning of
the resulting region with the element 'e' of the Golay alphabet is
carried out. The number of iterations for this step is determined
by the parameter Iterations2. The skiz operation serves
to compute a kind of skeleton of the input regions, and to prune the
branches of the resulting skeleton. If the skiz operation is
applied to the complement of the region, the region and the
resulting skeleton are separated.
If very large values or 'maximal' are passed for
Iterations1 or Iterations2, the processing
stops if no more changes occur.
Region (input_object) region(-array) → object
Regions to be thinned.

Let F be the area of the input region. Then the runtime complexity for one region is
morph_skiz returns 2 (
H_MSG_TRUE)
if all parameters are correct.
The behavior in case of empty or no input region can be set via:
empty region:
set_system('empty_region_result',<RegionResult>)
Otherwise, an exception is raised.
