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.

Controlling architecture generation with AutoKeras' AutoModel

Letting AutoKeras automagically figure out what architecture works best is great, but it can be time-consuming – unacceptably so at times.

Can we exert more control? Can we hint at which options work best for our particular problem? Can we meet AutoML halfway by providing a set of guidelines it must follow according to our prior knowledge or preference, but still give it enough leeway to experiment?

Yes, we can, and in this recipe, you'll learn how by utilizing a special feature in AutoKeras known as AutoModel!

How to do it…

Follow these steps to learn how to customize the search space of the NAS algorithm with AutoModel:

  1. The first thing we need to do is import all the necessary dependencies:
    from autokeras import *
    from tensorflow.keras.datasets import fashion_mnist as fm
    from tensorflow.keras.models import load_model
    from tensorflow.keras.utils import *
  2. Because we'll...
