Computer vision on mobile devices is becoming more and more popular. Personal gadgets are now powerful enough to process high-resolution images, stitch panoramas, and detect and track objects. OpenCV, with its decent performance and wide range of functionality, can be an extremely useful tool in the hands of iOS developers.Instant OpenCV for iOS is a practical guide that walks you through every important step for building a computer vision application for the iOS platform. It will help you to port your OpenCV code, profile and optimize it, and wrap it into a GUI application. Each recipe is accompanied by a sample project or an example that helps you focus on a particular aspect of the technology.Instant OpenCV for iOS starts by creating a simple iOS application and linking OpenCV before moving on to processing images and videos in real-time. It covers the major ways to retrieve images, process them, and view or export results. Special attention is also given to performance issues, as they greatly affect the user experience.Several computer vision projects will be considered throughout the book. These include a couple of photo filters that help you to print a postcard or add a retro effect to your images. Another one is a demonstration of the facial feature detection algorithm. In several time-critical cases, the processing speed is measured and optimized using ARM NEON and the Accelerate framework.OpenCV for iOS gives you all the information you need to build a high-performance computer vision application for iOS devices.

As hundreds of millions of people have started using Android smartphones, embedded Linux systems are becoming more and more popular. To get more market share, not only for hardware and function piling up, smartphone manufacturers gradually realized the importance of user experience. To improve user experience, the back-end Linux system must be optimized in many ways.Instant Optimizing Embedded System Using BusyBox is a practical, hands-on guide that provides you with a number of clear, step-by-step exercises to help you take advantage of the real power behind Busybox, and give you a good grounding for using it to optimize your embedded (Android Linux) systems.Moving on from the basics, this book will teach you how to configure and compile it from source code, including cross-compiling it with static linking and dynamic linking. You will also learn how to install and use Busybox on the Android emulator. You will learn to replace the simple Android mksh console with Busybox ash console and start a telnet and HTTP service provided by Busybox. You will also build embedded Linux file system from scratch and start it on Android emulator. We will take a look at how to add functionality to Busybox based system, including adding external applets to Busybox, as well as building development environments (like Bash and C) for it manually or with the automatic Buildroot system.If want to learn how to take advantage of using Busybox applets to optimize your embedded system, then this is the book for you for it will also show you how to use the powerful applets to optimize multiple aspects of an embedded (Android Linux) system.This book will teach you how to build an embedded (Android Linux) system with Busybox, enhance its functionality to meet diverse system requirements, and optimize it to provide a better user experience for embedded products.
