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.

Working with the basic building blocks of the Keras API

Keras is the official high-level API for TensorFlow 2.x and its use is highly encouraged for both experimental and production-ready code. Therefore, in this first recipe, we'll review the basic building blocks of Keras by creating a very simple fully connected neural network.

Are you ready? Let's begin!

Getting ready

At the most basic level, a working installation of TensorFlow 2.x is all you need.

How to do it…

In the following sections, we'll go over the sequence of steps required to complete this recipe. Let's get started:

  1. Import the required libraries from the Keras API:
    from sklearn.model_selection import train_test_split
    from sklearn.preprocessing import LabelBinarizer
    from tensorflow.keras import Input
    from tensorflow.keras.datasets import mnist
    from tensorflow.keras.layers import Dense
    from tensorflow.keras.models import Model
    from tensorflow.keras.models import Sequential...
