Hello

I dont understand where exactly do i write the filename or pathname of image in the most basic code , I have tried different versions of code and successsfulyl loaded images ..bt the documentation has the following code :

include <opencv2 core="" core.hpp="">

include <opencv2 highgui="" highgui.hpp="">

include <iostream>

using namespace cv; using namespace std;

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

Mat image;
image = imread(argv[1], CV_LOAD_IMAGE_COLOR);   // Read the file

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

namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
imshow( "Display window", image );                   // Show our image inside it.

waitKey(0);                                          // Wait for a keystroke in the window
return 0;

}

PLS tell me where do i write the pathname/filename to load my image.
