Screenlab is powered by the OpenCV computer vision library. By pulling together efforts from across industry and academia the open source OpenCV has become one of the most powerful computer vision tools available.
We leverage this power to provide the Screenlab service, but OpenCV is used in a huge number of areas. Check out Christian Perone's blog for his experiments using OpenCV to track visual markers from a home-made drone.
