Signature
Description
morph_hatmorph_hatMorphHatMorphHatmorph_hat computes the union of the regions that are
removed by an openingopeningOpeningOpeningopening operation with the regions that are
added by a closingclosingClosingClosingclosing operation. Hence this is the union
of the results of top_hattop_hatTopHatTopHattop_hat and bottom_hatbottom_hatBottomHatBottomHatbottom_hat.
The position of StructElementStructElementStructElementstructElementstruct_element does not influence the
result.
Structuring elements (StructElementStructElementStructElementstructElementstruct_element) can be generated
with operators such as gen_circlegen_circleGenCircleGenCirclegen_circle, gen_rectangle1gen_rectangle1GenRectangle1GenRectangle1gen_rectangle1,
gen_rectangle2gen_rectangle2GenRectangle2GenRectangle2gen_rectangle2, gen_ellipsegen_ellipseGenEllipseGenEllipsegen_ellipse,
draw_regiondraw_regionDrawRegionDrawRegiondraw_region, gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygongen_region_polygon,
gen_region_pointsgen_region_pointsGenRegionPointsGenRegionPointsgen_region_points, etc.
Attention
The individual regions are processed separately.
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.

Result
morph_hatmorph_hatMorphHatMorphHatmorph_hat 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.
