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.

Visualizing a model's architecture

Due to their complexity, one of the most effective ways to debug a neural network is by visualizing its architecture. In this recipe, we'll learn about two different ways we can display a model's architecture:

  • Using a text summary
  • Using a visual diagram

Getting ready

We'll need both Pillow and pydot to generate a visual representation of a network's architecture. We can install both libraries using pip, as follows:

$> pip install Pillow pydot

How to do it…

Visualizing a model's architecture is pretty easy, as we'll learn in the following steps:

  1. Import all the required libraries:
    from PIL import Image
    from tensorflow.keras import Model
    from tensorflow.keras.layers import BatchNormalization
    from tensorflow.keras.layers import Conv2D
    from tensorflow.keras.layers import Dense
    from tensorflow.keras.layers import Dropout
    from tensorflow.keras.layers import Flatten
    from tensorflow...
