Mobile devices running Google's Android outnumber all other mobile OSes and, in recent years, they have featured incredible computing power alongside high-quality cameras, which allows them to perform computer vision at the highest levels. One of the most sought after applications for mobile computer vision is augmented reality(AR). Blending real and virtual worlds has applications in entertainment and gaming, medicinel and healthcare, industry and defense, and many more. The world of mobile AR is advancing quickly, with new compelling demos popping up daily, and it is undeniably an engine for mobile hardware and software development. In this chapter, we will learn how to implement an AR application from scratch in the Android ecosystem, by using OpenCV's ArUco contrib
module, Android's Camera2 APIs, as well as the jMonkeyEngine 3D game engine. However, first we will begin with simply calibrating our Android device's camera...

Overview of this book
OpenCV is one of the best open source libraries available and can help you focus on constructing complete projects on image processing, motion detection, and image segmentation.
This Learning Path is your guide to understanding OpenCV concepts and algorithms through real-world examples and activities. Through various projects, you'll also discover how to use complex computer vision and machine learning algorithms and face detection to extract the maximum amount of information from images and videos. In later chapters, you'll learn to enhance your videos and images with optical flow analysis and background subtraction. Sections in the Learning Path will help you get to grips with text segmentation and recognition, in addition to guiding you through the basics of the new and improved deep learning modules. By the end of this Learning Path, you will have mastered commonly used computer vision techniques to build OpenCV projects from scratch. This Learning Path includes content from the following Packt books:
•Mastering OpenCV 4 - Third Edition by Roy Shilkrot and David Millán Escrivá
•Learn OpenCV 4 By Building Projects - Second Edition by David Millán Escrivá, Vinícius G. Mendonça, and Prateek Joshi
