Add an image opened using #OpenCV as a texture in OpenGL

I was toying with OpenCV since a long time. Here is a tutorial on how to download and configure eclipse for OpenCV. OpenCV (Open Source Computer Vision) is a library of programming functions mainly aimed at real-time computer vision. Originally developed by Intel's research center in Nizhny Novgorod (Russia), it was later supported by Willow Garage and is now maintained by Itseez.

In this C++ project in Eclipse an image is opened using imread method of OpenCV tool and the opened image is used as a texture to map to a polygon drawn across the screen. Actually this image in the window is itself a snapshot of another program which does texture mapping inside a 3D house scene program. I could have chosen any other image.
