Chapter 10. Face Recognition and Face Emotion Recognition

In the previous chapter, we looked at how to detect objects such as a car, chair, cat, and dog, using Convolutional Neural Networks and the YOLO (You Only Look Once) algorithm. In this chapter, we will be detecting human faces. Apart from that, we will be looking at expressions of the human face, such as a human face seeming happy, neutral, sad, and so on. So, this chapter will be interesting, because we are going to focus on some of the latest techniques of face detection and face emotion recognition. We are dividing this chapter into two parts:

• Face detection

• Face emotion recognition

First, we will cover how face detection works, and after that, we will move on to the face emotion recognition part. In general, we will cover the following topics in this chapter:

• Introducing the problem statement

• Setting up the coding environment

• Understanding the concepts of face recognition

• Approaches for implementing face recognition

• Understanding the...
