title: Relative versus Absolute path to cv::imread OpenCV
body: <p>I've got a cross platform error with OpenCV 2.3.1 and 2.4 on both VS2010 and Xcode 4.2</p>
  
  <p>If I use cv::imread while giving the path to the image as an absolute path, it works. It does not work if that is a relative path. I usually put the images in the same dir as the code as well as all other dirs in the project just to be careful.</p>
  
  <p>Much appreciated if anyone can answer this. Thank you!</p>
