In this chapter, we will cover the main topics in connection with face processing. In order to do so, we will be using the OpenCV library, but also the dlib (http://dlib.net/python/index.html, https://pypi.org/project/dlib/, https://github.com/davisking/dlib), face_recognition (https://pypi.org/project/face_recognition/, https://github.com/ageitgey/face_recognition) and cvlib (https://pypi.org/project/cvlib/, https://github.com/arunponnusamy/cvlib, https://www.cvlib.net/) Python packages. In the previous section, you saw how to install these packages.
In order to introduce this chapter, we will be using different approaches throughout all the sections to see the different possibilities you have at hand to solve a concrete face processing task, and it can be helpful to have a high-level overview of all of these alternatives.
