Overview of this book

OpenCV is one of the best open source libraries available, and can help you focus on constructing complete projects on image processing, motion detection, and image segmentation. Whether you’re completely new to computer vision, or have a basic understanding of its concepts, Learn OpenCV 4 by Building Projects – Second edition will be your guide to understanding OpenCV concepts and algorithms through real-world examples and projects. You’ll begin with the installation of OpenCV and the basics of image processing. Then, you’ll cover user interfaces and get deeper into image processing. As you progress through the book, you'll learn complex computer vision algorithms and explore machine learning and face detection. The book then guides you in creating optical flow video analysis and background subtraction in complex scenes. In the concluding chapters, you'll also learn about text segmentation and recognition and understand the basics of the new and improved deep learning module. By the end of this book, you'll be familiar with the basics of Open CV, such as matrix operations, filters, and histograms, and you'll have mastered commonly used computer vision techniques to build OpenCV projects from scratch.

Technical requirements

To follow the chapter with ease, it is required that you install OpenCV with the deep learning module compiled. If you do not have this module, you will not be able to compile and run the sample codes.

It's very useful to have an NVIDIA GPU with CUDA support. You can enable CUDA on OpenCV to improve the speed of training and detection.

Finally, you can download the code used in this chapter from https://github.com/PacktPublishing/Learn-OpenCV-4-By-Building-Projects-Second-Edition/tree/master/Chapter_12.
