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.

Video retargeting

Video synthesis is a broad term used for describing all forms of video generation. This can include generating video from random noise or words, to colorize black-and-white video, and so on, much like image generation.

In this section, we will look at a subgroup of video synthesis known as video retargeting. We will first look at two applications – face reenactment and pose transfer – and then introduce a powerful model that uses motion to generalize video targeting.

Face reenactment

Face reenactment was introduced along with face swapping in Chapter 9, Video Synthesis. Face reenactment in video synthesis involves transferring the facial expression of the driving video to the face in the target video. This is useful in animation and movie making. Recently, Zakharov et al. proposed a generative model that requires only a few target 2D images. This is done by using facial landmarks as intermediate features, as shown in the following diagram:
