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.

Technical requirements

This chapter's project has the following software dependencies:

  • A Python environment with the following modules: OpenCV, NumPy, SciPy, PyFFTW, and wxPython.
  • Optional: Spinnaker SDK and PySpin. These are available for Windows and Linux, but not Mac.

Where not otherwise noted, setup instructions are covered in Chapter 1, Preparing for the Mission. Setup instructions for PyFFTW are covered in Chapter 7, Seeing a Heartbeat with a Motion-Amplifying Camera, in the Choosing and setting up an FFT library section. Setup instructions for Spinnaker SDK and PySpin are covered in the current chapter, in the Installing Spinnaker SDK and PySpin section. Always refer to the setup instructions for any version requirements. Basic instructions for running Python code are covered in Appendix C, Running with Snakes (or First Steps with Python).
