I made an example, loading an image from disk and dísplaying it on the screen. I am using visual studio 2008 and used the code below:

image description

The following error appears:

1>c:\users\dell\documents\visual studio 2008\projects\llllllll\llllllll\llllllll.cpp(11) : error C2065: '“Example1”' : undeclared identifier
1>c:\users\dell\documents\visual studio 2008\projects\llllllll\llllllll\llllllll.cpp(12) : error C2065: '“Example1”' : undeclared identifier

I think "example1 " is the image I want to load. I placed it inside the c++ file, I tried but program is not active!

Help me please!

Why do you use the old deprecated c style? Try c++ which will also be supported in the future.

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main( int argc, char** argv ){
   Mat image = imread( argv[1], CV_LOAD_IMAGE_COLOR);

   if(!image.data ){
      cout << "No image - no Display \n";
      return -1;
   }

   namedWindow( "Display Image", CV_WINDOW_AUTOSIZE );
   imshow( "Display Image", image );

   waitKey(0);
   return 0;
}

I am wondering why he doesn't have straight quotes. Probably it could get solved quite fast by using normal standard quotes.

Probably he is also missing the .jpg or .png( or whatever). I dont think it will work by only having the image name

The way this is programmed, it you need to add the path of the image location in your VS2008 project settings to the debug options. Else please use an absolute path for the imread like c:/image.png
