C++ OpenCV “Cannot find or open PDB file” and "(opencv_world310.dll) in Project2.exe: Access violation reading location

Question

I'm new at programing and I get stuck in my visual studio using C++ and openCV, because when I run some code the program give output : Cannot find or open PDB file and (opencv_world310.dll) in Project2.exe: 0xC0000005: Access violation reading location 0x00000000056AE000. I don't know what should i do, i try some solution on Internet but cant solve my problem in whole week :(

This is my code:

#include "opencv2/opencv.hpp"

using namespace cv;
using namespace std;

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

    // Read image
    Mat im = imread("cow.jpg");
    Mat imout, imout_gray;

    // Edge preserving filter with two different flags.
    edgePreservingFilter(im, imout, RECURS_FILTER);
    imwrite("edge-preserving-recursive-filter.jpg", imout);

    edgePreservingFilter(im, imout, NORMCONV_FILTER);
    imwrite("edge-preserving-normalized-convolution-filter.jpg", imout);

    // Detail enhance filter
    detailEnhance(im, imout);
    imwrite("detail-enhance.jpg", imout);

    // Pencil sketch filter
    pencilSketch(im, imout_gray, imout);
    imwrite("pencil-sketch.jpg", imout_gray);

    // Stylization filter
    stylization(im, imout);
    imwrite("stylization.jpg", imout);
}

and this is my output:

The program '[8724] Project2.exe' has exited with code 0 (0x0).

Please can anyone help me to solve this one? :(

Thanks^^

PDB Files are used for debugging. You can load them by doing :

>Debug/Options/Symboles and now check "Microsoft Symbols Servers"

Try to open your image "cow.jpg" first and show it with: imshow("myWindows",im); to see if your image is correctly loaded and comments other lines.

Remember to include opencv dependencies in :

Project Properties/Linker/Input/Supplementary Dependencies

Add the paths (depends to your installation)

C:\\OpenCV_31\\opencv\\build\\x64\\vc14\\lib\\opencv_world310.lib C:\\OpenCV_31\\opencv\\build\\x64\\vc14\\lib\\opencv_world310d.lib
