Chapter 8. Face Recognition using Eigenfaces or Fisherfaces

This chapter will introduce concepts in face detection and face recognition and provide a project to detect faces and recognize them when it sees them again. Face recognition is both a popular and a difficult topic, and many researchers devote years to the field of face recognition. So this chapter will explain simple methods of face recognition, giving the reader a good start if they want to explore more complex methods.

In this chapter, we cover the following:

• Face detection

• Face preprocessing

• Training a machine-learning algorithm from collected faces

• Face recognition

• Finishing touches
