 Finally, to update the content of the OpenCV window with a new image use the @ref cv::imshow
 function. Specify the OpenCV window name to update and the image to use during this operation:

 Because we want our window to be displayed until the user presses a key (otherwise the program would
 end far too quickly), we use the @ref cv::waitKey function whose only parameter is just how long
 should it wait for a user input (measured in milliseconds). Zero means to wait forever.
