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.

Creating a basic image classifier

We'll close this chapter by implementing an image classifier on Fashion-MNIST, a popular alternative to mnist. This will help us consolidate the knowledge we've acquired from the previous recipes. If, at any point, you need more details on a particular step, please refer to the previous recipes.

Getting ready

I encourage you to complete the five previous recipes before tackling this one since our goal is to come full circle with the lessons we've learned throughout this chapter. Also, make sure you have Pillow and pydot on your system. You can install them using pip:

$> pip install Pillow pydot

Finally, we'll use the tensorflow_docs package to plot the loss and accuracy curves of the model. You can install this library with the following command:

$> pip install git+https://github.com/tensorflow/docs
