OpenCV 4 Computer Vision Application Programming Cookbook

Discover interesting recipes to help you understand the concepts of object detection image processing and facial detectionKey FeaturesExplore the latest features and APIs in OpenCV 4 and build computer vision algorithmsDevelop effective robust and fail-safe vision for your applicationsBuild computer vision algorithms with machine learning capabilitiesBook DescriptionOpenCV is an image and video processing library used for all types of image and video analysis. Throughout the book youll work through recipes that implement a variety of tasks such as facial recognition and detection. With 70 self-contained tutorials this book examines common pain points and best practices for computer vision (CV) developers. Each recipe addresses a specific problem and offers a proven best-practice solution with insights into how it works so that you can copy the code and configuration files and modify them to suit your needs.This book begins by setting up OpenCV and explains how to manipulate pixels. Youll understand how you can process images with classes and count pixels with histograms. Youll also learn detecting describing and matching interest points. As you advance through the chapters youll get to grips with estimating projective relations in images reconstructing 3D scenes processing video sequences and tracking visual motion. In the final chapters youll cover deep learning concepts such as face and object detection.By the end of the book youll be able to confidently implement a range to computer vision algorithms to meet the technical requirements of your complex CV projectsWhat you will learnInstall and create a program using the OpenCV librarySegment images into homogenous regions and extract meaningful objectsApply image filters to enhance image contentExploit image geometry to relay different views of a pictured sceneCalibrate the camera from different image observationsDetect people and objects in images using machine learning techniquesReconstruct a 3D scene from imagesExplore face detection using deep learningWho this book is forIf you’re a CV developer or professional who already uses or would like to use OpenCV for building computer vision software this book is for you. You’ll also find this book useful if you’re a C++ programmer looking to extend your computer vision skillset by learning OpenCV.
