Comparing screen capturing using GDI+ and OpenCV on Windows in C++

To follow up on my last two blogs (Capturing the screen on Windows in C++ using OpenCV & Capturing the screen on Windows in C++ using GDI+ ), we compare in this post both approaches. In order to compare both approaches, we examines their run-times and CPU usages.
