Detailed Description

Class that tracks in an image a edge defined by a Nurbs.

The advantage of this class is that it enables to track an edge whose equation is not known in advance. At each iteration, the Nurbs corresponding to the edge is computed.

It is possible to have a direct access to the nurbs. It is indeed a public parameter.

The code below shows how to use this class.

#include <visp3/core/vpImage.h>
#include <visp3/core/vpImagePoint.h>
#include <visp3/me/vpMeNurbs.h>
int main()
{
  vpImage<unsigned char> I(240, 320);
  // Fill the image with a black rectangle
  I = 0;
  for (int i = 100; i < 180; i ++) {
    for (int j = 0; j < 320; j ++) {
      I[i][j] = 255;
    }
  }
  // Set the moving-edges tracker parameters
  vpMe me;
  me.setRange(25);
  me.setPointsToTrack(20);
  me.setThreshold(15000);
  me.setSampleStep(10);
  // Initialize the moving-edges tracker parameters
  vpMeNurbs meNurbs;
  meNurbs.setNbControlPoints(4);
  meNurbs.setMe(&me);
  // Initialize the location of the edge to track (here a horizontal line
  std::list<vpImagePoint> ipList; //List of points belonginig to the edge
  ipList.push_back(vpImagePoint(110,119));
  ipList.push_back(vpImagePoint(140,119));
  ipList.push_back(vpImagePoint(160,119));
  ipList.push_back(vpImagePoint(170,119));
  meNurbs.initTracking(I, ipList);
  while ( 1 )
  {
    // ... Here the code to read or grab the next image.
    // Track the line.
    meNurbs.track(I);
  }
  return 0;
}

Note: It is possible to display the nurbs as an overlay. For that you must use the display function of the class vpMeNurbs.; In case of an edge which is not smooth, it can be interesting to use the canny detection to find the extremities. In this case, use the method setEnableCannyDetection to enable it. Warning : This function requires OpenCV.

void vpMeTracker::display ( const vpImage< unsigned char > & I )

virtualinherited

Display the moving edge sites with a color corresponding to their state.

If green : The vpMeSite is a good point.
If blue : The point is removed because of the vpMeSite tracking phase (constrast problem).
If purple : The point is removed because of the vpMeSite tracking phase (threshold problem).
If red : The point is removed because of the robust method in the virtual visual servoing (M-Estimator problem).
If cyan : The point is removed because it's too close to another.
Yellow otherwise

Parameters

I	: The image.
