Hands-On Image Generation with TensorFlow

Chapter 1: Getting Started with Image Generation Using TensorFlow

This book focuses on generating images and videos using unsupervised learning with TensorFlow 2. We assume that you have prior experience in using modern machine learning frameworks, such as TensorFlow 1, to build image classifiers with Convolutional Neural Networks (CNNs). Therefore, we will not be covering the basics of deep learning and CNNs. In this book, we will mainly use high level Keras APIs in TensorFlow 2, which is easy to learn. Nevertheless, we assume that you have no prior knowledge of image generation, and we will go through all that is needed to help you get started with it. The first aspect that you need to know about is probability distribution.

Probability distribution is fundamental in machine learning and it is especially important in generative models. Don't worry, I assure you that there aren't any complex mathematical equations in this chapter. We will first learn what probability is and how to use it to generate faces without using any neural networks or complex algorithms.

That's right: with the help of only basic math and NumPy code, you'll learn how to create a probabilistic generative model. Following that, you will learn how to use TensorFlow 2 to build a PixelCNN model in order to generate handwritten digits. This chapter is packed with useful information; you will need to read this chapter before jumping to any other chapters.

In this chapter, we are going to cover the following main topics:

  • Understanding probabilities
  • Generating faces with a probabilistic model
  • Building a PixelCNN model from scratch

Key benefits

  • Understand the different architectures for image generation, including autoencoders and GANs
  • Build models that can edit an image of your face, turn photos into paintings, and generate photorealistic images
  • Discover how you can build deep neural networks with advanced TensorFlow 2.x features

Description

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.

Who is this book for?

The Hands-On Image Generation with TensorFlow book is for deep learning engineers, practitioners, and researchers who have basic knowledge of convolutional neural networks and want to learn various image generation techniques using TensorFlow 2.x. You’ll also find this book useful if you are an image processing professional or computer vision engineer looking to explore state-of-the-art architectures to improve and enhance images and videos. Knowledge of Python and TensorFlow will help you to get the best out of this book.

What you will learn

  • Train on face datasets and use them to explore latent spaces for editing new faces
  • Get to grips with swapping faces with deepfakes
  • Perform style transfer to convert a photo into a painting
  • Build and train pix2pix, CycleGAN, and BicycleGAN for image-to-image translation
  • Use iGAN to understand manifold interpolation and GauGAN to turn simple images into photorealistic images
  • Become well versed in attention generative models such as SAGAN and BigGAN
  • Generate high-resolution photos with Progressive GAN and StyleGAN

The book is well written. The author explained step by step of Deep learning implementation using Python and TensorFlow library. The GAN implementation requires a lot of effort from the scratch. But if you follow the book, you can save a your learning time and model building time. I recommend to buy this book.

Disclaimer: The publisher asked me to review the book and gave me a review copy. This represents my opinion on the book.The book is well outlined, organized, and easy to use. I read about and implemented, with the help of the book, the Variational Autoencoder to explore a representation/generation space of data at work. As a practical person I liked the book a lot.The book is a great quickstart into representation with neural networks. (I also read it more deeply at times and it is great for that as well. I myself have experience with high-throughput large scale autoencoders with TensorFlow and building Facial Recognition applications. I appreciated this book a lot.)

This book is a simple cookbook approach to building projects with VAEs and GANs. The book comes along with actual TensorFlow (python) code samples, in the form of Jupyter Notebooks (.ipynb). So, it is very helpful to read through the material and quickly work on simple GAN projects. Initial chapters explain concepts in brief as expected and then starts discussing more complex approaches in later chapters. This book is however low on the math behind GANs and does not discuss how to debug GANs when they don't work.Note: Advanced chapters in this book present complex projects which require multi-GPU systems! I'm yet to get to those projects at the time of this review.

The author provided me a free copy and asked me to write a review here.I think overall it is a decent book. It covered most of the state of the art algorithms. Also it strike the right balance of the algorithm intuition and implementation details. There is a complimentary github comes with this book, which is very nice. The code shown in the book is mostly written in tensorflow 2 or keras. I think this book is more like a technical handbook covering many dots rather than a textbook built you foundation and insights.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
