morph_hatmorph_hatMorphHatMorphHatmorph_hat (Operator)

Name

morph_hatmorph_hatMorphHatMorphHatmorph_hat — Vereinigen von bottom_hatbottom_hatBottomHatBottomHatBottomHatbottom_hat und top_hattop_hatTopHatTopHatTopHattop_hat.

Warnung

morph_hatmorph_hatMorphHatMorphHatMorphHatmorph_hat ist veraltet und wird nur aus Gründen der Rückwärtskompatibilität zur Verfügung gestellt.

Signatur

morph_hat(Region, StructElement : RegionMorphHat : : )

Beschreibung

morph_hatmorph_hatMorphHatMorphHatMorphHatmorph_hat vereinigt die Flächen, die bei der openingopeningOpeningOpeningOpeningopening-Operation wegfallen mit den Flächen, die bei der closingclosingClosingClosingClosingclosing-Operation hinzukommen. Dies entspricht also der Vereinigung von top_hattop_hatTopHatTopHatTopHattop_hat und bottom_hatbottom_hatBottomHatBottomHatBottomHatbottom_hat. Die Position von StructElementStructElementStructElementStructElementstructElementstruct_element ist ohne Bedeutung.

Das strukturierende Element (StructElementStructElementStructElementStructElementstructElementstruct_element) kann mit Operatoren wie 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. erzeugt werden.

Achtung

Die Regionen werden einzeln bearbeitet.

Ausführungsinformationen

Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
Automatisch parallelisiert auf Tupelebene.

Strukturierendes Element (lageinvariant).

RegionMorphHatRegionMorphHatRegionMorphHatRegionMorphHatregionMorphHatregion_morph_hat (output_object) region(-array) → object

Vereinigung von Top-Hat und Bottom-Hat.

Beispiel (C++)

#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 ();

Ergebnis

Bei korrekter Parametrisierung liefert die Funktion morph_hatmorph_hatMorphHatMorphHatMorphHatmorph_hat den Wert 2 (H_MSG_TRUE). Das Funktionsverhalten für die beiden Fälle leere und keine Eingaberegion lässt sich wie folgt kontrollieren:

Andernfalls wird eine Fehlerbehandlung durchgeführt.
