Get started in the rapidly expanding field of computer vision with this practical guide. Written by Adrian Kaehler and Gary Bradski, creator of the open source OpenCV library, this book provides a thorough introduction for developers, academics, roboticists, and hobbyists. YouOll learn what it takes to build applications that enable computers to see and make decisions based on that data.With over 500 functions that span many areas in vision, OpenCV is used for commercial applications such as security, medical imaging, pattern and face recognition, robotics, and factory product inspection. This book gives you a firm grounding in computer vision and OpenCV for building simple or sophisticated vision applications. Hands-on exercises in each chapter help you apply what youOve learned.This volume covers the entire library, in its modern C++ implementation, including machine learning tools for computer vision.O Learn OpenCV data types, array types, and array operationsO Capture and store still and video images with HighGUIO Transform images to stretch, shrink, warp, remap, and repairO Explore pattern recognition, including face detectionO Track objects and motion through the visual fieldO Reconstruct 3D images from stereo visionO Discover basic and advanced machine learning techniques in OpenCV
