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.

Conditional GANs

The first goal of a generative model is to be able to produce good quality images. Then we would like to be able to have some control over the images that are to be generated.

In Chapter 1, Getting Started with Image Generation Using TensorFlow, we learned about conditional probability and generated faces with certain attributes using a simple conditional probabilistic model. In that model, we generated a smiling face by forcing the model to only sample from the images that had a smiling face. When we condition on something, that thing will always be present and will no longer be a variable with random probability. You can also see that the probability of having those conditions is set to 1.

To enforce the condition on a neural network is simple. We simply need to show the labels to the network during training and inference. For example, if we want the generator to generate the digit 1, we will need to present the label of 1 in addition to the usual random...
