Hands-On Image Generation with TensorFlow

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.

Image translation with pix2pix

The introduction of pix2pix in 2017 caused quite a stir, not only within the research community, but also the wider population. This can be attributed in part to the https://affinelayer.com/pixsrv/ website, which puts the models online and allows people to translate their sketches into cats, shoes, and bags. You should try it too! The following screenshot is taken from their website to give you a glimpse of how it works:

Pix2pix came from a research paper entitled Image-to-Image Translation with Conditional Adversarial Networks. From the paper title, we can tell that pix2pix is a conditional GAN that performs image-to-image translation. The model can be trained to perform general image translation, but we will need to have image pairs in the dataset. In our pix2pix implementation, we will translate masks of...
