title: OpenCV error: "Cannot load image!"
body: <p>After compiling OpenCV's source and configuring Windows 7 and VS2010 to link the libraries correctly, I was able to compile the following code: </p>
  
  <pre><code>#include &lt;opencv2/highgui/highgui.hpp&gt;
  #include &lt;iostream&gt;
  
  using namespace cv;
  using namespace std;
  int main()
  {
      Mat im = imread("C:\projects\cvtest3\lena.jpg"); // this *is* the proper path, I'm sure
  
      if (im.empty()) 
      {
  
          cout &lt;&lt; "Cannot load image!" &lt;&lt; endl;
                  while (true){}
          return -1;
      }
      imshow("Image", im);
      waitKey(0);
  }
  </code></pre>
  
  <p>Even though the path is correctly specified I can't get this code to show the lena image. Is there anything wrong with the code here? </p>
  
  <p>Although the code compiles, this is the full output while building: </p>
