lowlandslowlandsLowlandsLowlandslowlands (Operator)

Name

lowlandslowlandsLowlandsLowlandslowlands — Detektieren aller Grauwert-Tiefebenen.

Signatur

lowlands(Image : Lowlands : : )

Beschreibung

lowlandslowlandsLowlandsLowlandslowlands wählt alle Punkte aus ImageImageImageimageimage aus, deren Grauwert nicht größer als der Grauwert ihrer Nachbarn (8er-Nachbarschaft) ist, und gibt sie in LowlandsLowlandsLowlandslowlandslowlands zurück. Jede Tiefebene ergibt eine eigene Region.

Ausführungsinformationen

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

Parameter

ImageImageImageimageimage (input_object) singlechannelimage(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real)

Zu verarbeitendes Bild.

LowlandsLowlandsLowlandslowlandslowlands (output_object) region-array → object

Gefundenen Tiefebenen als Regionen (für jede Tiefebene eine Region).

Beispiel (C++)

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

int main (int argc, char *argv[])
{
  if (argc != 2)
  {
    cout << "Usage : " << argv[0] << " <name of image>" << endl;
    return (-1);
  }

  HImage   image (argv[1]);
  HWindow  win;

  image.Display (win);

  HImage       cres = image.CornerResponse (5, 0.04);
  HRegionArray mins = cres.Lowlands ();

  win.SetColored (12);
  mins.Display (win);
  win.Click ();

  return (0);
}
