Overview of this book

Computer vision (CV) is a field of artificial intelligence that helps transform visual data into actionable insights to solve a wide range of business challenges. This book provides prescriptive guidance to anyone looking to learn how to approach CV problems for quickly building and deploying production-ready models. You’ll begin by exploring the applications of CV and the features of Amazon Rekognition and Amazon Lookout for Vision. The book will then walk you through real-world use cases such as identity verification, real-time video analysis, content moderation, and detecting manufacturing defects that’ll enable you to understand how to implement AWS AI/ML services. As you make progress, you'll also use Amazon SageMaker for data annotation, training, and deploying CV models. In the concluding chapters, you'll work with practical code examples, and discover best practices and design principles for scaling, reducing cost, improving the security posture, and mitigating bias of CV workloads. By the end of this AWS book, you'll be able to accelerate your business outcomes by building and implementing CV into your production environments with the help of AWS AI/ML services.

Building a model to identify Packt’s logo

In this section, we will see how to train a model to identify Packt’s logo using Rekognition Custom Labels. We’ll collect training and test datasets for Packt’s logo, label the images and draw bounding boxes, and train the model.

Step 1 – Collecting your images

Upload the sample images from the book’s GitHub repository. You can complete this step using the following command:

$ aws s3 sync 03_RekognitionCustomLabels/images s3://cv-on-aws-book-xxxx/chapter_03/images --region us-east-2

Important note

To collect the sample images, you can use the same S3 bucket you created in Chapter 2.

Now, navigate to Amazon Rekognition on the AWS Management Console ( Select on Use Custom Labels on the left sidebar and then Select on Get started:
