TensorFlow 2.0 Computer Vision Cookbook

By: Jesús Martínez

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 10: Applying the Power of Deep Learning to Videos

Computer vision is focused on the understanding of visual data. Of course, that includes videos, which, at their core, are a sequence of images, which means we can leverage most of our knowledge regarding deep learning for image processing to videos and reap great results.

In this chapter, we'll start training a convolutional neuronal network to detect emotions in human faces, and then we'll learn how to apply it in a real-time context using our webcam.

Then, in the remaining recipes, we'll use very advanced implementations of architectures, hosted in TensorFlow Hub (TFHub), specially tailored to tackle interesting video-related problems such as action recognition, frames generation, and text-to-video retrieval.

Here are the recipes that we will be covering shortly:

  • Detecting emotions in real time
  • Recognizing actions with TensorFlow Hub
  • Generating the middle frames of a video with TensorFlow...
