Key benefits

  • Discover how to build, train, and serve your own deep neural networks with TensorFlow 2 and Keras
  • Apply modern solutions to a wide range of applications such as object detection and video analysis
  • Learn how to run your models on mobile devices and web pages and improve their performance

Description

Computer vision solutions are becoming increasingly common, making their way into fields such as health, automobile, social media, and robotics. This book will help you explore TensorFlow 2, the brand new version of Google's open source framework for machine learning. You will understand how to benefit from using convolutional neural networks (CNNs) for visual tasks. Hands-On Computer Vision with TensorFlow 2 starts with the fundamentals of computer vision and deep learning, teaching you how to build a neural network from scratch. You will discover the features that have made TensorFlow the most widely used AI library, along with its intuitive Keras interface. You'll then move on to building, training, and deploying CNNs efficiently. Complete with concrete code examples, the book demonstrates how to classify images with modern solutions, such as Inception and ResNet, and extract specific content using You Only Look Once (YOLO), Mask R-CNN, and U-Net. You will also build generative adversarial networks (GANs) and variational autoencoders (VAEs) to create and edit images, and long short-term memory networks (LSTMs) to analyze videos. In the process, you will acquire advanced insights into transfer learning, data augmentation, domain adaptation, and mobile and web deployment, among other key concepts. By the end of the book, you will have both the theoretical understanding and practical skills to solve advanced computer vision problems with TensorFlow 2.0.

Who is this book for?

If you’re new to deep learning and have some background in Python programming and image processing, like reading/writing image files and editing pixels, this book is for you. Even if you’re an expert curious about the new TensorFlow 2 features, you’ll find this book useful. While some theoretical concepts require knowledge of algebra and calculus, the book covers concrete examples focused on practical applications such as visual recognition for self-driving cars and smartphone apps.

What you will learn

  • Create your own neural networks from scratch
  • Classify images with modern architectures including Inception and ResNet
  • Detect and segment objects in images with YOLO, Mask R-CNN, and U-Net
  • Tackle problems faced when developing self-driving cars and facial emotion recognition systems
  • Boost your application's performance with transfer learning, GANs, and domain adaptation
  • Use recurrent neural networks (RNNs) for video analysis
  • Optimize and deploy your networks on mobile devices and in the browser

Being quite new in the field of Computer Vision, I have found this book to be a very good reference especially when it comes to translate the concepts of Deep Learning into actual code. It has certainly helped me to reduce the time I'd spend googling for examples and such. Plus, the explanations provided are very clear and I'd definitely recommend this book if you looking for a starting point to get into Computer Vision.

Great read for both beginners and experienced enthusiasts! Authors provide an easy to follow introduction to deep learning and its mathematical foundations as well as the code and exercises to enhance your understanding. I, personally, used the book to get to know TF 2 (already having some experience with other frameworks) and it served me very well. Highly recommended!

The book provides a clear mathematical background for understanding neural networks. The theoretical explanations are illustrated by applications inspired from historical image processing riddles. This makes it quite interesting to follow the book as it is correlated to real-life problems and doesn't take shortcuts by oversimplifying things.I had no prior experience with Python, so it was quite challenging for me to get started. But even so I went trough the first chapter without any major issue.It worked best for me to juggle back and forth between the book (to get the theoretical understanding) and the Jupiter Notebook/online code (to apply the concepts and follow the program examples)

The book is a light reference for those starting out in computer vision. The authors provide an overview of different problems and share code snippets for deep learning-based solutions. It is well written on the whole and has enough detail for software engineers and machine learning engineers to get an initial prototype up and running for their problems. Considering this is a book, the authors could have shared some additional insight into why certain types of convolutional blocks improved performance over others and why they work for specific problems.

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.
