Hands-On Image Generation with TensorFlow

By: Soon Yau Cheong

Overview of this book

The emerging field of Generative Adversarial Networks (GANs) has made it possible to generate indistinguishable images from existing datasets. With this hands-on book, you’ll not only develop image generation skills but also gain a solid understanding of the underlying principles. Starting with an introduction to the fundamentals of image generation using TensorFlow, this book covers Variational Autoencoders (VAEs) and GANs. You’ll discover how to build models for different applications as you get to grips with performing face swaps using deepfakes, neural style transfer, image-to-image translation, turning simple images into photorealistic images, and much more. You’ll also understand how and why to construct state-of-the-art deep neural networks using advanced techniques such as spectral normalization and self-attention layer before working with advanced models for face generation and editing. You'll also be introduced to photo restoration, text-to-image synthesis, video retargeting, and neural rendering. Throughout the book, you’ll learn to implement models from scratch in TensorFlow 2.x, including PixelCNN, VAE, DCGAN, WGAN, pix2pix, CycleGAN, StyleGAN, GauGAN, and BigGAN. By the end of this book, you'll be well versed in TensorFlow and be able to implement image generative technologies confidently.

Chapter 3: Generative Adversarial Network

Generative Adversarial Network, more commonly known as GANs, are currently the most prominent method in image and video generation. As the inventor of the convolutional neural network, Dr. Yann LeCun, said in 2016, "...it is the most interesting idea in the last 10 years in machine learning." The images generated using GANs are superior, in terms of realism, to other competing technologies and things have advanced tremendously since their invention in 2014 by then graduate student Ian Goodfellow.

In this chapter, we will first learn about the fundamentals of GANs and build a DCGAN to generate Fashion MNIST. We'll learn about the challenges in training GANs. Finally, we will learn how to build a WGAN and its variant, WGAN-GP, to resolve many of the challenges involved in generating faces.

In this chapter, we will cover the following topics:

  • Understanding the fundamentals of GANs
  • Building a Deep Convolutional...
