Thanks for the awnser ! What driver do you used to have ? Updated from Nvidia Geforce Xperience ? I just reinstaled windows 10 and it's not happening now but may if i install the lastest driver it crashes. I wont just in case. Thanks a lot ^^

Hi everybody ! :)

I'm having several problems to run my OpenCV based projects on my computer. I'm using OpenCV 3.1.0 with Visual Studio 2015 so i'm using vc14 .lib and .dll. The official web page of OpenCV says that 3.1.0 has Visual Studio 14 2015 support so i don't think that this is the problem.

The code i'm runing is this :

enter code here
#include<stdio.h>
#include<math.h>
#include<opencv\cv.h>
#include<opencv\highgui.h>
#include<opencv2\objdetect\objdetect.hpp>
#include<opencv2\highgui\highgui.hpp>
#include<opencv2\imgproc\imgproc.hpp>
#include<vector>

using namespace cv;
using namespace std;

int main()
{
       CascadeClassifier face_cascade, eye_cascade;
   if (!face_cascade.load("haarcascade_frontalface_alt.xml")) {
    printf("Error loading cascade file for face");
    return 1;
}
if (!eye_cascade.load("haarcascade_eye.xml")) {
    printf("Error loading cascade file for eye");
    return 1;
}
VideoCapture capture(0); //-1, 0, 1 device id
if (!capture.isOpened())
{
    printf("error to initialize camera");
    return 1;
}
Mat cap_img, gray_img;
vector<Rect> faces, eyes;
while (1)
{
    capture >> cap_img;
    waitKey(10);
    cvtColor(cap_img, gray_img, CV_BGR2GRAY);
    cv::equalizeHist(gray_img, gray_img);
    face_cascade.detectMultiScale(gray_img, faces, 1.1, 10, CV_HAAR_SCALE_IMAGE | CV_HAAR_DO_CANNY_PRUNING, cvSize(0, 0), cvSize(300, 300));
    for (int i = 0; i < faces.size(); i++)
    {
        Point pt1(faces[i].x + faces[i].width, faces[i].y + faces[i].height);
        Point pt2(faces[i].x, faces[i].y);
        Mat faceROI = gray_img(faces[i]);
        eye_cascade.detectMultiScale(faceROI, eyes, 1.1, 2, 0 | CV_HAAR_SCALE_IMAGE, Size(30, 30));
        for (size_t j = 0; j< eyes.size(); j++)
        {
            //Point center(faces[i].x+eyes[j].x+eyes[j].width*0.5, faces[i].y+eyes[j].y+eyes[j].height*0.5);
            Point center(faces[i].x + eyes[j].x + eyes[j].width*0.5, faces[i].y + eyes[j].y + eyes[j].height*0.5);
            int radius = cvRound((eyes[j].width + eyes[j].height)*0.25);
            circle(cap_img, center, radius, Scalar(255, 0, 0), 2, 8, 0);
        }
        rectangle(cap_img, pt1, pt2, cvScalar(0, 255, 0), 2, 8, 0);
    }
    imshow("Result", cap_img);
    waitKey(3);
    char c = waitKey(3);
    if (c == 27)
        break;
}
return 0;
}

It's just an example that i found on the internet.

Please i really want to learn about OpenCV but i can't run anything :(

I'm using Windows 8.1

Thank everybody :) I wish i could help in the future!
