Beschreibung

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

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

#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;

  }

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

  image.Display (win);

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

  win.SetColored (12);
