“This is not a college textbook. It provides enough material to learn machine learning and with hands on code. You may feel it's been rushed. But as technology changes everyday, you have to sacrifice something to get to the reader asap. I like this bo...”
data, and much moreAll the code examples in the book are based on OpenCV 3.1 – the latest versionWho This Book Is ForThis is the perfect book for anyone who wants to dive into the exciting world of image processing and computer vision. This book is aimed at programmers with a working knowledge of C++. Prior knowledge of OpenCV or Computer Vision/Machine Learning is not required.What You Will LearnExplore the steps involved in building a typical computer vision/machine learning applicationUnderstand the relevance of OpenCV at every stage of building an applicationHarness the vast amount of information that lies hidden in images into the apps you buildIncorporate visual information in your apps to create more appealing softwareGet acquainted with how large-scale and popular image editing apps such as Instagram work behind the scenes by getting a glimpse of how the image filters in apps can be recreated using simple operations in OpenCVAppreciate how difficult it is for a computer program to perform tasks that are trivial for human beingsGet to know how to develop applications that perform face detection, gender detection from facial images, and handwritten character (digit) recognitionIn DetailComputer vision and machine learning concepts are frequently used in practical computer vision based projects. If you’re a novice, this book provides the steps to build and deploy an end-to-end application in the domain of computer vision using OpenCV/C++.At the outset, we explain how to install OpenCV and demonstrate how to run some simple programs. You will start with images (the building blocks of image processing applications), and see how they are stored and processed by OpenCV. You’ll get comfortable with OpenCV-specific jargon (Mat Point, Scalar, and more), and get to know how to traverse images and perform basic pixel-wise operations.Building upon this, we introduce slightly more advanced image processing concepts such as filtering, thresholding, and edge detection. In the latter parts, the book touches upon more complex and ubiquitous concepts such as face detection (using Haar cascade classifiers), interest point detection algorithms, and feature descriptors. You will now begin to appreciate the true power of the library in how it reduces mathematically non-trivial algorithms to a single line of code!The concluding sections touch upon OpenCV’s Machine Learning module. You will witness not only how OpenCV helps you pre-process and extract features from images that are relevant to the problems you are trying to solve, but also how to use Machine Learning algorithms that work on these features to make intelligent predictions from visual data!Style and approachThis book takes a very hands-on approach to developing an end-to-end application with OpenCV. To avoid being too theoretical, the description of concepts are accompanied simultaneously by the development of applications. Throughout the course of the book, the projects and practical, real-life examples are explained and developed step by step in sync with the theory.
