Overview of this book

Computer vision is a scientific field that enables machines to identify and process digital images and videos. This book focuses on independent recipes to help you perform various computer vision tasks using TensorFlow. The book begins by taking you through the basics of deep learning for computer vision, along with covering TensorFlow 2.x’s key features, such as the Keras and tf.data.Dataset APIs. You’ll then learn about the ins and outs of common computer vision tasks, such as image classification, transfer learning, image enhancing and styling, and object detection. The book also covers autoencoders in domains such as inverse image search indexes and image denoising, while offering insights into various architectures used in the recipes, such as convolutional neural networks (CNNs), region-based CNNs (R-CNNs), VGGNet, and You Only Look Once (YOLO). Moving on, you’ll discover tips and tricks to solve any problems faced while building various computer vision applications. Finally, you’ll delve into more advanced topics such as Generative Adversarial Networks (GANs), video processing, and AutoML, concluding with a section focused on techniques to help you boost the performance of your networks. By the end of this TensorFlow book, you’ll be able to confidently tackle a wide range of computer vision problems using TensorFlow 2.x.

Chapter 2: Performing Image Classification

Computer vision is a vast field that takes inspiration from many places. Of course, this means that its applications are wide and varied. However, the biggest breakthroughs over the past decade, especially in the context of deep learning applied to visual tasks, have occurred in a particular domain known as image classification.

As the name suggests, image classification consists of the process of discerning what's in an image based on its visual content. Is there a dog or a cat in this image? What number is in this picture? Is the person in this photo smiling or not?

Because image classification is such an important and pervasive task in deep learning applied to computer vision, the recipes in this chapter will focus on the ins and outs of classifying images using TensorFlow 2.x.

We'll cover the following recipes:

  • Creating a binary classifier to detect smiles
  • Creating a multi-class classifier to play Rock Paper Scissors
  • Creating a multi-label classifier to label watches
  • Implementing ResNet from scratch
  • Classifying images with a pre-trained network using the Keras API
  • Classifying images with a pre-trained network using TensorFlow Hub
  • Using data augmentation to improve performance with the Keras API
  • Using data augmentation to improve performance with the tf.data and tf.image APIs
