OpenCV is one of the most popular libraries used to develop computer vision applications. It enables us to run many different computer vision algorithms in real time. It has been around for many years, and it has become the standard library in this field. One of the main advantages of OpenCV is that it is highly optimized and available on almost all platforms.

This book starts off by giving a brief introduction to the various fields in computer vision and the associated OpenCV functionalities in C++. Each chapter contains real-world examples and code samples to demonstrate the use cases. This helps you to easily grasp the topics and understand how they can be applied in real life. To sum up, this is a practical guide on how to use OpenCV in C++ and build various applications using this library.
