Loading images in Argument

edit savecancel

Hi, i have to load 4 images that i uploaded in the Argument section(run-run properties- arguments) and i am trying to load them with "argv[i]". I always have the same input: Usage: display_image ImageToLoadAndDisplay

Can you please tell me where is the error? i think it may be in the Arguments field, maybe there is some special character to divide arguments, by now i am just writing the location of the image with one space within every location. This is my code.

int main( int argc, char** argv )
{
    if( argc != 2)
    {
        cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
        return -1;
    }

    Mat  images[4];
    Mat spectrum[4];
    for (int i=1;i<5;i++)
    {
        images[i-1]=imread(argv[i], CV_LOAD_IMAGE_GRAYSCALE );

        if(! images[i-1].data )                              // Check for invalid input
            {
                cout <<  "Could not open or find the image" << std::endl ;
                return -1;
            }

    Fourier(images[i-1],spectrum[i-1]);

    string name="image number "+ i;
    string nameSpectrum= "spectrum number " + i;
    namedWindow(name, CV_WINDOW_AUTOSIZE );
    imshow(name, images[i] );

    namedWindow(nameSpectrum, CV_WINDOW_AUTOSIZE );
    imshow(nameSpectrum, spectrum[i] );
    waitKey(0);

    }
