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.

Implementing DeepDream

DeepDream is the result of an experiment that aimed to visualize the internal patterns that are learned by a neural network. In order to achieve this goal, we can pass an image through the network, compute its gradient with respect to the activations of a specific layer, and then modify the image to increase the magnitude of such activations to, in turn, magnify the patterns. The result? Psychedelic, surreal photos!

Although this recipe is a bit complex due to the nature of DeepDream, we will take it one step at a time, so don't worry.

Let's get started.

Getting ready

We don't need to install anything extra for this recipe. However, we won't dive deep into the details of DeepDream, but if you're interested in the topic, you can read the original blog post by Google here: https://ai.googleblog.com/2015/06/inceptionism-going-deeper-into-neural.html.
