Summary

What's new in OpenCV 5

If you are an OpenCV veteran, you might want to know more about OpenCV 5's changes before you decide to install it. Here are some of the highlights:

The C++ implementation of OpenCV has been updated to C++14. 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.
Support for Python 2 has been dropped because this Python version is obsolete and no longer maintained. If you have any old Python 2 projects, you should upgrade them to Python 3.
For many algorithms, support for named parameters has been added in order to make the initialization code more concise and readable.
For the pip package installer, the opencv-python and opencv-contrib-python packages are now maintained by the core OpenCV team rather than a third party. The opencv-contrib-python-nonfree package has been discontinued due to patent restrictions.
The SIFT algorithm...
