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 a U-Net with transfer learning

Training a U-Net from scratch is a very good first step toward creating a performant image segmentation system. However, one of the biggest superpowers in deep learning that's applied to computer vision is being able to build solutions on top of the knowledge of other networks, which usually leads to faster and better results.

Image segmentation is no exception to this rule, and in this recipe, we'll implement a better segmentation network using transfer learning.

Let's begin.

Getting ready

This recipe is very similar to the previous one (Implementing a U-Net from scratch), so we'll only go into depth on the parts that are different. For a deeper explanation, I recommend that you complete the Implementing a U-Net from scratch recipe before attempting this one. As expected, the libraries we'll need are the same as they were for that recipe, all of which can be installed using pip. Let's start with...
