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.

Putting your skills into practice

Now, you can apply the skills you have learned to implement your own image generation projects. Before you start, there are some pitfalls you should look out for and also some practical advice that you can follow.

Don't trust everything you read

A new academic paper is published and shows astonishing images generated by their model! Take it with a pinch of salt. Usually, these papers handpick the best result to showcase and hide the failed examples. Furthermore, the images are shrunk down to fit onto the paper, thus the image artifacts may not be visible from the paper. Before investing your time in using or re-implementing the information in the paper, try to find other resources of the claimed results. This can be the author's website or GitHub repository, which may contain the raw, high-definition images and videos.
