I would vote for the includes, and the C-style function.

include <highgui.h>

include <cv.h>

With these I'm not sure that you'll get what you need. The right way to do the includes is

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

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

Those includes above will reference to the old legacy versions of opencv still available in some Ubuntu versions.

Also if you are developing a new code (and I can see that it's C++) please use the new C++ API to easily avoid problems like memory leaks and such. Too bad that 95% of the example materials that can be found (official&unofficial) on OpenCV are still advertising the old API. For example your line of code would look like this:

if( !cv::imread("13_45_07-65.bmp").empty() ) cout << "sorry" << endl;
