morph_skeletonmorph_skeletonMorphSkeletonMorphSkeletonmorph_skeleton (Operator)
Name
morph_skeletonmorph_skeletonMorphSkeletonMorphSkeletonmorph_skeleton — Compute the morphological skeleton of a region.
Warning
morph_skeletonmorph_skeletonMorphSkeletonMorphSkeletonmorph_skeleton is obsolete and is only provided for
reasons of backward compatibility.
Signature
def morph_skeleton(region: HObject) -> HObject
Description
morph_skeletonmorph_skeletonMorphSkeletonMorphSkeletonmorph_skeleton computes the skeleton of the input
regions (RegionRegionRegionregionregion) using morphological transformations.
The computation yields a disconnected skeleton (gaps in the
diagonals) having a width of one or two pixels. The calculation
uses the Golay element 'h', i.e., an 8-neighborhood. This is
equivalent to the maximum-norm.
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.
Parameters
RegionRegionRegionregionregion (input_object) region(-array) → objectHRegionHObjectHObjectHobject
Regions to be processed.

Resulting morphological skeleton.
Result
morph_skeletonmorph_skeletonMorphSkeletonMorphSkeletonmorph_skeleton returns 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>)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>)set_system("empty_region_result",<RegionResult>)
Otherwise, an exception is raised.
