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 convolutional autoencoder

As with regular neural networks, when it comes to images, using convolutions is usually the way to go. In the case of autoencoders, this is no different. In this recipe, we'll implement a convolutional autoencoder to reproduce images from Fashion-MNIST.

The distinguishing factor is that in the decoder, we'll use reverse or transposed convolutions, which upscale volumes instead of downscaling them. This is what happens in traditional convolutional layers.

This is an interesting recipe. Are you ready to begin?

Getting ready

Because there are convenience functions in TensorFlow for downloading Fashion-MNIST, we don't need to do any manual preparations on the data side. However, we must install OpenCV so that we can visualize the outputs of the autoencoder. This can be done with the following command:

$> pip install opencv-contrib-python

Without further ado, let's get started.
