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.

Generating your own dreamy images

Deep learning has an entertaining side. DeepDream is one application that aims to understand the inner workings of deep neural networks by exciting certain activations on selected layers. However, beyond the investigative intent of the experiment, it also produces psychedelic, dream-like fun images.

In this recipe, we'll experiment with several configurations of DeepDream on a test image and see how they affect the results.

Getting ready

We'll use the DeepDreamer() implementation from the first recipe of this chapter (Implementing DeepDream). Although I encourage you to try this out with your own images, if you want to follow this recipe as closely as possible, you can download the sample image here: https://github.com/PacktPublishing/Tensorflow-2.0-Computer-Vision-Cookbook/tree/master/ch4/recipe2/road.jpg.

Let's take a look at the sample image:
