Overview of this book

Computer vision is a rapidly evolving science in the field of artificial intelligence, encompassing diverse use cases and techniques. This book will not only help those who are getting started with computer vision but also experts in the domain. You'll be able to put theory into practice by building apps with OpenCV 5 and Python 3. You'll start by setting up OpenCV 5 with Python 3 on various platforms. Next, you'll learn how to perform basic operations such as reading, writing, manipulating, and displaying images, videos, and camera feeds. From taking you through image processing, video analysis, depth estimation, and segmentation, to helping you gain practice by building a GUI app, this book ensures you'll have opportunities for hands-on activities. You'll tackle two popular challenges: face detection and face recognition. You'll also learn about object classification and machine learning, which will enable you to create and use object detectors and even track moving objects in real time. Later, you'll develop your skills in augmented reality and real-world 3D navigation. Finally, you'll cover ANNs and DNNs, learning how to develop apps for recognizing handwritten digits and classifying a person's gender and age, and you'll deploy your solutions to the Cloud. By the end of this book, you'll have the skills you need to execute real-world computer vision projects.

In this chapter we will take OpenCV to the cloud, by exploring technologies and methodologies that will allow you to package your application and deploy it on AWS so it can be made available to the public even at large scale, without having to learn lengthy and complex technologies to maintain such applications.

We will provide a brief introduction to containers and containerization tools like Docker, an overview of the AWS cloud provider and AWS Lambda, and finally we will demonstrate how to develop a simple application and deploy it.

NOTE: even if you don’t want to use AWS, the knowledge you will acquire about containerization should seamlessly transfer to other cloud providers or cloud-agnostic solutions such as Kubernetes (which can be deployed on any cloud).

IMPORTANT NOTE: to follow the examples in this chapter you will need an AWS account. While you have to provide credit card credentials, if you follow...
