I'm trying to run this code in VS13 that uses command line argument I'm following this method but its nt working.

Solution Explorer Properties Debugging Command Arguments "D:/Images/image1.jpeg" "D:/Images/image2.jpeg"

Code:

#include <opencv2\core\core.hpp>
#include <opencv2\highgui\highgui.hpp>
#include <stdio.h>
#include <iostream>


using namespace std;
using namespace cv;

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

Mat img;
Mat img2;

img = imread(argv[1], CV_LOAD_IMAGE_COLOR);
img2 = imread(argv[2], CV_LOAD_IMAGE_COLOR);

if (img.empty() || img2.empty)
{
    cout << "Error: Image cannot be loaded!" << endl;
    system("pause");
    return -1;
}

namedWindow("Image", CV_WINDOW_AUTOSIZE);
imshow("Image", img);
namedWindow("Imag2", CV_WINDOW_AUTOSIZE);
imshow("Image2", img2);

waitKey(0);
return 0;

}

What do you mean by "not working"?

I think that's a small mistake 

namedWindow("Imag**e**2", CV_WINDOW_AUTOSIZE);
imshow("Image2", img2);

sorry friend @LBerger you pointed out the right mistake but unfortunately the code even doesn't reach there. It gives "Error The image can't be loaded" as i mentioned i'm unable to load my images by command line arguments.

There is an another error with empty img2.empty()

may be you should try like this to check some values :

cout << "argc ="<<argc<<"\n";
cout<<"Try to load "<<argv[1];
img = imread(argv[1], CV_LOAD_IMAGE_COLOR);
if (img.empty() )
{
    cout << "\nError: Image cannot be loaded!" << endl;
    system("pause");
    return -1;
}
cout<<"\nTry to load "<<argv[2];
img2 = imread(argv[2], CV_LOAD_IMAGE_COLOR);

if (img2.empty())
{
    cout << "\nError: Image cannot be loaded!" << endl;
    system("pause");
    return -1;
}

@LBerger: these errors doesn't matter unless at least single image is read, which is not done :/ and i'm confused why is that.. :(

You shouldn't use duplicate post. About your problem know there is no problem in your program.

Problem is in given path. Can you check what happen using debugger for example? I think somebody give you a remark like don't use / in cmd line argument. Use windows path "D:\Images\image1.jpeg".

You can use / when you path is written like imread("D:/Images/image1.jpeg", CV_LOAD_IMAGE_COLOR); and of course check path ( don't forget white space, ...)
