• Master fundamental concepts in computer vision and image processing
• Learn about the important classes and functions of OpenCV with complete working examples applied to real images

Book Description

Making your applications see has never been easier with OpenCV. With it, you can teach your robot how to follow your cat, write a program to correctly identify the members of One Direction, or even help you find the right colors for your redecoration.

OpenCV 3 Computer Vision Application Programming Cookbook Third Edition provides a complete introduction to the OpenCV library and explains how to build your first computer vision program. You will be presented with a variety of computer vision algorithms and exposed to important concepts in image and video analysis that will enable you to build your own computer vision applications.

This book helps you to get started with the library, and shows you how to install and deploy the OpenCV library to write effective computer vision applications following good programming practices. You will learn how to read and write images and manipulate their pixels. Different techniques for image enhancement and shape analysis will be presented. You will learn how to detect specific image features such as lines, circles or corners. You will be introduced to the concepts of mathematical morphology and image filtering.

The most recent methods for image matching and object recognition are described, and you’ll discover how to process video from files or cameras, as well as how to detect and track moving objects. Techniques to achieve camera calibration and perform multiple-view analysis will also be explained. Finally, you’ll also get acquainted with recent approaches in machine learning and object classification.

What you will learn

• Install and create a program using the OpenCV library
• Process an image by manipulating its pixels
• Analyze an image using histograms
• Segment images into homogenous regions and extract meaningful objects
• Apply image filters to enhance image content
• Exploit the image geometry in order to relay different views of a pictured scene
• Calibrate the camera from different image observations
• Detect faces and people in images using machine learning techniques
