Signature

morph_hat(Region, StructElement : RegionMorphHat : : )

Description

morph_hatmorph_hatMorphHatMorphHatMorphHatmorph_hat computes the union of the regions that are removed by an openingopeningOpeningOpeningOpeningopening operation with the regions that are added by a closingclosingClosingClosingClosingclosing operation. Hence this is the union of the results of top_hattop_hatTopHatTopHatTopHattop_hat and bottom_hatbottom_hatBottomHatBottomHatBottomHatbottom_hat. The position of StructElementStructElementStructElementStructElementstructElementstruct_element does not influence the result.

Structuring elements (StructElementStructElementStructElementStructElementstructElementstruct_element) can be generated with operators such as gen_circlegen_circleGenCircleGenCircleGenCirclegen_circle, gen_rectangle1gen_rectangle1GenRectangle1GenRectangle1GenRectangle1gen_rectangle1, gen_rectangle2gen_rectangle2GenRectangle2GenRectangle2GenRectangle2gen_rectangle2, gen_ellipsegen_ellipseGenEllipseGenEllipseGenEllipsegen_ellipse, draw_regiondraw_regionDrawRegionDrawRegionDrawRegiondraw_region, gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon, gen_region_pointsgen_region_pointsGenRegionPointsGenRegionPointsGenRegionPointsgen_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.

Parameters

RegionRegionRegionRegionregionregion (input_object) region(-array) → object

Regions to be processed.

StructElementStructElementStructElementStructElementstructElementstruct_element (input_object) region → object

Structuring element (position-invariant).

RegionMorphHatRegionMorphHatRegionMorphHatRegionMorphHatregionMorphHatregion_morph_hat (output_object) region(-array) → object

Union of top hat and bottom hat.

Example (C++ (HALCON 5.0-10.0))

#include "HIOStream.h"
#if !defined(USE_IOSTREAM_H)
using namespace std;
#endif
#include "HalconCpp.h"

main()
{
  cout << "Reproduction of 'dilation_circle ()'" << endl;
  cout << "First = original image " << endl;
  cout << "Red   = after segmentation " << endl;
  cout << "Blue  = after erosion " << endl;

  HByteImage img("monkey");
  HWindow    w;

  HRegion      circ   = HRegion::GenCircle (10, 10, 1.5);
  HRegionArray regs   = (img >= 128).Connection();
  HRegionArray tophat = regs.TopHat (circ);
  HRegionArray bothat = regs.BottomHat (circ);
  HRegionArray unionX = tophat.Union2 (bothat);

                        img.Display (w);      w.Click ();
  w.SetColor ("red");   regs.Display (w);     w.Click ();

  w.SetColor ("green"); bothat.Display (w);   w.Click ();

  return(0);

Result

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

Otherwise, an exception is raised.
