Synopsis

Expand your knowledge of computer vision by building amazing projects with OpenCV 3

About This Book

• Build computer vision projects to capture high-quality image data, detect and track objects, process the actions of humans or animals, and much more
• Discover practical and interesting innovations in computer vision while building atop a mature open-source library, OpenCV 3
• Familiarize yourself with multiple approaches and theories wherever critical decisions need to be made

Who This Book Is For

This book is ideal for you if you aspire to build computer vision systems that are smarter, faster, more complex, and more practical than the competition.This is an advanced book intended for those who already have some experience in setting up an OpenCV development environment and building applications with OpenCV. You should be comfortable with computer vision concepts, object-oriented programming, graphics programming, IDEs, and the command line.

What You Will Learn

• Select and configure camera systems to see invisible light, fast motion, and distant objects
• Build a "camera trap", as used by nature photographers, and process photos to create beautiful effects
• Develop a facial recognition system with various feature extraction techniques and machine learning methods
• Build a panorama Android application using the OpenCV stitching module in C++ with NDK support
• Optimize your object detection model, make it rotation invariant, and apply scene-specific constraints to make it faster and more robust
• Create a person identification and registration system based on biometric properties of that person, such as their fingerprint, iris, and face
• Fuse data from videos and gyroscopes to stabilize videos shot from your mobile phone and create hyperlapse style videos

In Detail

Computer vision is becoming accessible to a large audience of software developers who can leverage mature libraries such as OpenCV. However, as they move beyond their first experiments in computer vision, developers may struggle to ensure that their solutions are sufficiently well optimized, well trained, robust, and adaptive in real-world conditions. With sufficient knowledge of OpenCV, these developers will have enough confidence to go about creating projects in the field of computer vision.

This book will help you tackle increasingly challenging computer vision problems that you may face in your careers. It makes use of OpenCV 3 to work around some interesting projects. Inside these pages, you will find practical and innovative approaches that are battle-tested in the authors' industry experience and research. Each chapter covers the theory and practice of multiple complementary approaches so that you will be able to choose wisely in your future projects. You will also gain insights into the architecture and algorithms that underpin OpenCV's functionality.

We begin by taking a critical look at inputs in order to decide which kinds of light, cameras, lenses, and image formats are best suited to a given purpose. We proceed to consider the finer aspects of computational photography as we build an automated camera to assist nature photographers. You will gain a deep understanding of some of the most widely applicable and reliable techniques in object detection, feature selection, tracking, and even biometric recognition. We will also build Android projects in which we explore the complexities of camera motion: first in panoramic image stitching and then in video stabilization.

By the end of the book, you will have a much richer understanding of imaging, motion, machine learning, and the architecture of computer vision libraries and applications!
