openCV facial recognition with Qt

[travis Haycock]

I have been able to get the webcam to activate but so far have not been able to get the facial recognition even after searching and looking at documentation in context of integration with other IDE's ; Visual Basic, I cannot successfully obtain the facial recognition portion ; here is my code:

   #include "mainwindow.h"
#include <QApplication>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/videoio/videoio.hpp>
#include<opencv2/objdetect/objdetect.hpp>
#include<opencv2/imgproc/imgproc.hpp>
#include<vector>
#include <iostream>
#include<stdio.h>
using namespace cv;
using namespace std;



class openCam{

public:

 void initiateCamera(){



         VideoCapture capture(0);
         if (!capture.isOpened()){
           std::cout << "Could not open VideoCapture" << std::endl;
 }

             Mat imgRead;

             for (;;){
               // capture a frame
               capture >> imgRead;
               imshow("Cam Interface", imgRead);
               // close if key pressed
               if(waitKey(27) > 0)
                   break;
             }

             capture.release();
             destroyAllWindows();


  }

};


// ************************************************************** MAIN

int main(int argc, char *argv[]){
    QApplication a(argc, argv);
    MainWindow w;
 // cam code
try{
  openCam cam;
   cam.initiateCamera();

}catch(Exception ex){
cout << "Unable to initiate camera" << std::endl;
    }


 w.show();
return a.exec();
}
