问题
i'm using dlib for face detection and i would like to write a text in the image.
i've tried this win.add_overlay(dets, rgb_pixel(255,0,0),"test" );
but it's not working
Can you please help me.

According to the dlib documentation, the add_overlay method takes an overlay as a parameter. Since you want to display rectangles you have to create an overlay_rect. You should try the following code :
win.add_overlay(dlib::image_window::overlay_rect(dets, rgb_pixel(255,0,0),"test" ));
dlib documentation is really well done (props to Davis King) you should take some time to read and understand it.
