The code is organized into folders, such as Chapter002, each corresponding to a chapter in the book. General familiarity with object-oriented programming, application development, and usage of operating systems (OS), developer tools, and the command line is required. The book will also help existing OpenCV users who want upgrade their projects to OpenCV 4 and new versions of other libraries, languages, tools, and operating systems. If you are an experienced software developer who is new to computer vision or machine learning, and wants to study these topics through creative projects, then this book is for you. If you feel this book is for you, get your copy today! Build OpenCV 4 Android applications in Android Studio and Unity. ![]() Build OpenCV 4 projects in Python 3 for desktops and Raspberry Pi.Make a physics simulation that detects shapes in a real-world drawing.Amplify motion in real-time video to show heartbeats and breaths.Detect and recognize human and cat faces to trigger an alarm.Detect car headlights and estimate distances to them.Detect motion and recognize gestures to control a smartphone game.This book covers the following exciting features: To target Android, the book supports Java in Android Studio, as well as C# in the Unity game engine. To target diverse desktop systems and Raspberry Pi, the book supports multiple Python versions (from 2.7 to 3.7). What a lot of gadgets we can build with such a handy library! OpenCV 4 for Secret Agents is a broad selection of projects based on computer vision, machine learning, and several application frameworks. It is open source, it supports many programming languages and platforms, and it is fast enough for many real-time applications. OpenCV 4 is a grand collection of image processing functions and computer vision algorithms. Use OpenCV 4 in secret projects to classify cats, reveal the unseen, and react to rogue drivers.
