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.

Translating unpaired images with CycleGAN

In the Translating images with Pix2Pix recipe, we discovered how to transfer images from one domain to another. However, in the end, it's supervised learning that requires a pairing of input and target images in order for Pix2Pix to learn the correct mapping. Wouldn't it be great if we could bypass this pairing condition, and let the network figure out on its own how to translate the characteristics from one domain to another, while preserving image consistency?

Well, that's what CycleGAN does, and in this recipe, we'll implement one from scratch to convert pictures of Yosemite National Park taken during the summer into their winter counterparts!

Let's get started.

Getting ready

We'll use OpenCV, tqdm, and tensorflow-datasets in this recipe.

Install these simultaneously with pip:

$> pip install opencv-contrib-python tqdm tensorflow-datasets

Through the TensorFlow datasets, we'll...
