'l', 'd', 'c', 'f', 'h', 'k'.
In order to compute the skeleton of a region, usually the elements
'l' and 'm' are used. Only the “foreground elements” (even
rotation numbers) are used. The elements 'i' and 'e' result in
unchanged output regions. The elements 'l', 'm' and 'f2' are
identical for the foreground. The Golay elements, together with all
possible rotations, are described with the operator
golay_elements golay_elements GolayElements GolayElements GolayElements golay_elements
Execution Information
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.

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