C++ OpenCV - Is there no way to remove title bar of a window?

Question

I am grabbing and displaying video using OpenCV and all I want is a window without the title bar. I've removed the Tool bar and Status bar but I also want to remove the title bar. I found some pointers using which I can display the video in fullscreen without title bar but I dont want that. Is there not any other way to do that? And I'm using Ubuntu 16.04
