Name

plateausplateausPlateausPlateaus — Detect all gray value plateaus.

Signature

plateaus(Image : Plateaus : : )

Herror plateaus(const Hobject Image, Hobject* Plateaus)

Herror T_plateaus(const Hobject Image, Hobject* Plateaus)

void Plateaus(const HObject& Image, HObject* Plateaus)

HRegion HImage::Plateaus() const

static void HOperatorSet.Plateaus(HObject image, out HObject plateaus)

HRegion HImage.Plateaus()

Description

plateausplateausPlateausPlateausPlateaus extracts all points from ImageImageImageImageimage with a gray value greater or equal to the gray value of its neighbors (8-neighborhood) and returns them in PlateausPlateausPlateausPlateausplateaus. Each maximum is returned as a separate region.

Example (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;
    return (-1);
  }

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

  image.Display (win);

  HImage       cres = image.CornerResponse (5, 0.04);
  HRegionArray maxi = cres.Plateaus ();

  win.SetColored (12);
