I'm currently trying to become familiar with OpenCV 2.4.2 but even the easiest programs just don't want to work :(

My small code:

int main(int argc, const char *argv[]) {

vector<Mat> faces;
vector<int> labels;

//Lade Bilder in Gesichts-Vector
faces.push_back(imread("path/person0_0.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0);
faces.push_back(imread("path/person0_1.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0);
faces.push_back(imread("path/person0_2.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0);
faces.push_back(imread("path/person0_3.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0);

//Erstelle einen FaceRecognizer
Ptr<FaceRecognizer> faceRec = createFisherFaceRecognizer();
//"trainiere" die Gesichter in den FaceRecognizer
faceRec->train(faces, labels);

return 0;


Eveything works until this line: faceRec->train(faces, labels);

Error Message: Error - RtlWerpReportException failed with status code :-1073741823. Will try to launch the process directly

I already looked into the API and found a example about face recognition. The example has exactly the same syntax as I have but it doesn't work. Has anybody an idea what's wrong with my code?

Greetings Mister004

Does the sample coming with OpenCV work for you? And is there any chance you paste the full program, with your includes? A quick Google Search shows, that a RtlWerpReportException almost always occurs with Qt. Are you including or using Qt?

If it isn't connected to Qt, then to reproduce I need to know:

  • Operating System, 32/64 bit?
  • Which compiler are you using?
  • Have you built OpenCV with Qt enabled?

Ok first thanks for the answer!

  1. No it does not
  2. I use Qt
  3. Operating system: Windows 7 64bit

Includes: include "opencv2/core/core.hpp" include "opencv2/contrib/contrib.hpp" include "opencv2/highgui/highgui.hpp"

using namespace cv; using namespace std;

The rest is the same as above
