What's new in OpenCV 4

If you are an OpenCV veteran, you might want to know more about OpenCV 4's changes before you decide to install it. Here are some of the highlights:

The C++ implementation of OpenCV has been updated to C++11. OpenCV's Python bindings wrap the C++ implementation, so as Python users, we may gain some performance advantages from this update, even though we are not using C++ directly.
The deprecated C implementation of OpenCV and the deprecated Python bindings for the C implementation have been removed.
Many new optimizations have been implemented. Existing OpenCV 3 projects can take advantage of many of these optimizations without further changes beyond updating the OpenCV version. For OpenCV C++ projects, an entirely new optimization pipeline named G-API is available; however, OpenCV's Python bindings currently do not support this optimization...
