Exploring Deepfakes

By: Bryan Lyon, Matt Tora

Overview of this book

Applying Deepfakes will allow you to tackle a wide range of scenarios creatively. Learning from experienced authors will help you to intuitively understand what is going on inside the model. You’ll learn what deepfakes are and what makes them different from other machine learning techniques, and understand the entire process from beginning to end, from finding faces to preparing them, training the model, and performing the final swap. We’ll discuss various uses for face replacement before we begin building our own pipeline. Spending some extra time thinking about how you collect your input data can make a huge difference to the quality of the final video. We look at the importance of this data and guide you with simple concepts to understand what your data needs to really be successful. No discussion of deepfakes can avoid discussing the controversial, unethical uses for which the technology initially became known. We’ll go over some potential issues, and talk about the value that deepfakes can bring to a variety of educational and artistic use cases, from video game avatars to filmmaking. By the end of the book, you’ll understand what deepfakes are, how they work at a fundamental level, and how to apply those techniques to your own needs.

Extracting Faces

In this chapter, we will start our hands-on activities with the code. To begin with, we’ll cover the process of extracting faces.

Extracting faces is a series of steps in a process that involves many different stages, but it’s the first discrete stage in creating a deepfake. This chapter will first talk about how to run the face extraction script, then we will go hands-on with the code, explaining what each part does.

In this chapter, we will cover the following key sections:

  • Getting image files from a video
  • Running extract on frame images
  • Getting hands-on with the code
