morph_skeletonmorph_skeletonmorph_skeletonMorphSkeletonMorphSkeleton (Operator)

Name

morph_skeletonmorph_skeletonmorph_skeletonMorphSkeletonMorphSkeleton — Compute the morphological skeleton of a region.

Signature

Description

morph_skeletonmorph_skeletonmorph_skeletonMorphSkeletonMorphSkeleton 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.

Parallelization

• 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

Result

morph_skeletonmorph_skeletonmorph_skeletonMorphSkeletonMorphSkeleton 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>)

• empty region: set_system('empty_region_result',<RegionResult>)

Otherwise, an exception is raised.
