OpenCV 4 for Secret Agents - Second Edition

By: Joseph Howse

Overview of this book

OpenCV 4 is a collection of image processing functions and computer vision algorithms. It is open source, supports many programming languages and platforms, and is fast enough for many real-time applications. With this handy library, you’ll be able to build a variety of impressive gadgets. OpenCV 4 for Secret Agents features a broad selection of projects based on computer vision, machine learning, and several application frameworks. To enable you to build apps for diverse desktop systems and Raspberry Pi, the book supports multiple Python versions, from 2.7 to 3.7. For Android app development, the book also supports Java in Android Studio, and C# in the Unity game engine. Taking inspiration from the world of James Bond, this book will add a touch of adventure and computer vision to your daily routine. You’ll be able to protect your home and car with intelligent camera systems that analyze obstacles, people, and even cats. In addition to this, you’ll also learn how to train a search engine to praise or criticize the images that it finds, and build a mobile app that speaks to you and responds to your body language. By the end of this book, you will be equipped with the knowledge you need to advance your skills as an app developer and a computer vision specialist.

Preface

Computer vision systems are deployed in the Arctic Ocean to spot icebergs at night. They are flown over the Amazon rainforest to create aerial maps of fires, blights, and illegal logging. They are set up in ports and airports worldwide to scan for suspects and contraband. They are sent to the depths of the Marianas Trench to guide autonomous submarines. They are used in operating rooms to help surgeons visualize the planned procedure and the patient's current condition. They are launched from battlefields as the steering systems of heat-seeking, anti-aircraft rockets.

We might seldom—or never—visit these places. However, stories often encourage us to imagine extreme environments and a person's dependence on tools in these unforgiving conditions. Perhaps fittingly, one of contemporary fiction's most popular characters is an almost ordinary man (handsome, but not too handsome; clever, but not too clever) who wears a suit, works for the British Government, always chooses the same drink, the same kind of woman, the same tone for delivering a pun, and is sent to do dangerous jobs with a peculiar collection of gadgets.

Bond. James Bond.

This book discusses seriously useful technologies and techniques, with a healthy dose of inspiration from spy fiction. The Bond franchise is rich in ideas about detection, disguise, smart devices, image capture, and sometimes, even computer vision specifically. With imagination, plus dedication to learning new skills, we can become the next generation of gadget makers to rival Bond's engineer, Q!
