Summary

By now, you should have a good understanding of how face detection and face recognition work, and how to implement them in Python and OpenCV 3.

Face detection and face recognition are constantly evolving branches of computer vision, with algorithms being developed continuously, and they will evolve even faster in the near future with the emphasis posed on robotics and the Internet of things.

For now, the accuracy of detection and recognition heavily depends on the quality of the training data, so make sure you provide your applications with high-quality face databases and you will be satisfied with the results.
