Expand your knowledge of computer vision by building amazing projects with OpenCV 3About This BookBuild computer vision projects to capture high-quality image data, detect and track objects, process the actions of humans or animals, and much moreDiscover practical and interesting innovations in computer vision while building atop a mature open-source library, OpenCV 3Familiarize yourself with multiple approaches and theories wherever critical decisions need to be madeWho This Book Is ForThis 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 LearnSelect and configure camera systems to see invisible light, fast motion, and distant objectsBuild a “camera trap”, as used by nature photographers, and process photos to create beautiful effectsDevelop a facial expression recognition system with various feature extraction techniques and machine learning methodsBuild a panorama Android application using the OpenCV stitching module in C++ with NDK supportOptimize your object detection model, make it rotation invariant, and apply scene-specific constraints to make it faster and more robustCreate a person identification and registration system based on biometric properties of that person, such as their fingerprint, iris, and faceFuse data from videos and gyroscopes to stabilize videos shot from your mobile phone and create hyperlapse style videosIn DetailComputer 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!Style and approachThis book covers a combination of theory and practice. We examine blueprints for specific projects and discuss the principles behind these blueprints, in detail.

In 1993, tragic turbulence takes over Ukraine in the post-communist spin-off. As if in somnambulism, Soviet war veterans and upstart businessmen listen to an American preacher of whose type there were plenty at the time in the post-Soviet territory. In Kharkiv, the young communist headquarters is now an advertising agency, and a youth radio station brings Western music, with Depeche Mode in the lead, into homes of ordinary people.

In the Grasshopper we find a love triangle. Olga, her rather boring husband preoccupied with his work, and a young artist. Olga craves the excitement of the artistic life and finds a new lease on romance with the colourful landscape designer, who takes her on a cruise. But not all is going to plan in this quintessentially Chekhovian love tale. Other stories in this volume include: A woman's Kingdom, Difficult People, A Dreary Story, The Privy Councillor.

Once upon a time there was a king and a queen, who were very sorry that they had no children, so sorry that it cannot be told. At last, however, the Queen had a daughter. There was a very fine christening; and the Princess had for her godmothers all the fairies they could find in the whole kingdom (there were seven of them), so that every one of them might confer a gift upon her, as was the custom of fairies in those days. By this means the Princess had all the perfections imaginable.

Once upon a time, long, long ago, there were two brothers, the one rich and the other poor. When Christmas Eve came, the poor one had not a bite in the house, either of meat or bread; so he went to his brother, and begged him, in God’s name, to give him something for Christmas Day. It was by no means the first time that the brother had been forced to give something to him...

Once upon a time, in a large forest, there lived an old woman and three maidens. They were all three beautiful, but the youngest was the fairest. Their hut was quite hidden by trees, and none saw their beauty but the sun by day, and the moon by night, and the eyes of the stars. The old woman kept the girls hard at work, from morning till night, spinning gold flax into yarn, and when one distaff was empty another was given them, so they had no rest...
