plateaus

Herror ::plateaus ( Hobject Image, Hobject *Plateaus ) HRegionArray HImage::Plateaus ( void ) const HRegionArray HImageArray::Plateaus ( void ) const

Detect all gray value plateaus.

::plateaus extracts all points with a gray value greater or equal to the gray value of its neighbors (8-connectivity). Each maximum is returned as a separate region.

Parameters

`Image` (input_object)	image(-array) `->` Hobject: HImage(Array) ( byte / int1 / int2 / int4 / real )
Image to be processed.

`Plateaus` (output_object)	region-array `->` Hobject : HRegionArray*
Extracted plateaus as regions (one region for each plateau).

Example

#include  <iostream.h>
#include  "HalconCpp.h"

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);
  maxi.Display (win);
  win.Click ();

  return (0);
}
