It is increasingly being adopted in Python for development. OpenCV has C++/C, Python, and Java interfaces with support for Windows, Linux, Mac, iOS, and Android. Developers using OpenCV build applications to process visual data; this can include live streaming data from a device like a camera, such as photographs or videos. OpenCV offers extensive libraries with over 500 functions This book demonstrates how to develop a series of intermediate to advanced projects using OpenCV and Python, rather than teaching the core concepts of OpenCV in theoretical lessons. Instead, the working projects developed in this book teach the reader how to apply their theoretical knowledge to topics such as image manipulation, augmented reality, object tracking, 3D scene reconstruction, statistical learning, and object categorization. By the end of this book, readers will be OpenCV experts whose newly gained experience allows them to develop their own advanced computer vision applications.Style and approach This book covers independent hands-on projects that teach important computer vision concepts like image processing and machine learning for OpenCV with multiple examples.

Build robust and scalable iOS and Mac OS X game applicationsAbout This BookLearn to use and implement the 23 Gang of Four design patterns using Swift 2Design and architect your code for Swift application developmentUnderstand the role, generic UML design, and participants in the class diagram of the pattern by implementing them in a step-by-step approach Who This Book Is For This book is intended for competent Swift developers who want to apply enduring design patterns with Swift to structure and scale their application code.What You Will LearnChoose the appropriate pattern depending on the problem to be solvedUnderstand the generic class diagram of each of the 23 GoF patterns and how each object participates in the patternUse Swift to implement these patterns even though the language doesn’t provide all of the object-oriented programming concepts such as abstract class, interface, and so onArchitect your software to avoid the overuse of memory, time spent on calculations, or high network trafficFind the best way to organize your code to make it more secure from the outside worldPrepare your code to make it more flexible when the consumer changes or the third-party component hidden code changesStructure your code to change the algorithm to apply at runtimeDeliver Flyweight responsibility to your objects In Detail Swift is a multi-paradigm language. It has expressive features familiar to those used to work with modern functional languages, while also keeping the object-oriented features of Objective-C. It remains compatible with Apple’s legacy codes and frameworks. A design pattern systematically names, motivates, and explains a general design that addresses a recurring design problem in object-oriented systems. It describes the problem, the solution, when to apply the solution, and its consequences. It also gives implementation hints and examples. Knowledge about design patterns is also one of the best ways to make you different compared to other low-level developers. This book shows you how to use Swift 2 to learn about 23 Gang of Four (GoF) design patterns, and is organized into three categories. The book will present you the five creational patterns, followed by the seven structural patterns, and finishing with the 11 behavioral patterns as defined by the GoF. Each chapter will introduce the pattern by defining its role, which common problems the pattern should be used for, its generic UML representation, how each objects presented in the class diagram participate in the pattern, and what the role of each of these objects is. The book then presents you with a concrete case as an illustration that will be used to implement the pattern using Swift.Style and approach A step-by-step tutorial completed with screenshots and code highlights wherever necessary. Each chapter discusses one or more patterns with its definitions and a simple-to-follow illustration case using a playground or XCText project to implement it with Swift.

After decades of service and years of watching her family's troubles splashed across the tabloids, Britain's Queen is beginning to feel her age. She needs some proper cheering up. An unexpected opportunity offers her relief: an impromptu visit to a place that holds happy memories—the former royal yacht, Britannia, now moored near Edinburgh. Hidden beneath a skull-emblazoned hoodie, the limber Elizabeth (thank goodness for yoga) walks out of Buckingham Palace into the freedom of a rainy London day and heads for King's Cross to catch a train to Scotland. But a characterful cast of royal attendants has discovered her missing. In uneasy alliance a lady-in-waiting, a butler, an equerry, a girl from the stables, a dresser, and a clerk from the shop that supplies Her Majesty's cheese set out to find her and bring her back before her absence becomes a national scandal.Mrs Queen Takes the Train is a clever novel, offering a fresh look at a woman who wonders if she, like Britannia herself, has, too, become a relic of the past. William Kuhn paints a charming yet biting portrait of British social, political, and generational rivalries—between upstairs and downstairs, the monarchy and the government, the old and the young. Comic and poignant, fast paced and clever, this delightful debut tweaks the pomp of the monarchy, going beneath its rigid formality to reveal the human heart of the woman at its center.

Ada Adverse was brought up in a deeply puritanical household where looking at a cake or using words containing more than one vowel were considered decadences punishable by a night in the coal cellar. But at fifteen she ran away from home and is now the world’s leading authority on Having Fun, which is definitely an actual job, she has ‘Fungineer’ printed on her business cards to prove it, though in retrospect she should have been more clear that this does not mean she specialises in mushrooms. Ada’s hobbies include topiary, mazes, homing pigeons, flea circuses, forming imaginary bands in her head, embalming things, tattoos, pylons, and the films of Billy Wilder. Ada’s dislikes include predatory mcaws, getting out the wrong side of the bed, collections of masks, and porcelain dolls with realistic teeth.
