OpenCV 4 for Secret Agents

By: Joseph Howse, Ponnusamy

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.

Setting up a development machine

We can develop our OpenCV applications on a desktop, a notebook, or even the humble Raspberry Pi (covered later, in the Setting up a Raspberry Pi section). Most of our apps have a memory footprint of less than 128 MB, so they can still run (albeit slowly) on old or low-powered machines. To save time, develop on your fastest machine first and test on slower machines later.

This book assumes that you have one of the following operating systems on your development machine:

  • Windows 7 SP 1, or a later version.
  • Mac OS 10.7 (Lion), or a later version.
  • Debian Jessie, a later version, or a derivative such as the following:
    • Raspbian 2015-09-25, or a later version
    • Ubuntu 14.04, or a later version
    • Linux Mint 17, or a later version
  • Fedora 28, a later version, or a derivative such as the following:
    • RHEL 8, or a later version
    • CentOS 8, or a later version...
