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. This Learning Path is your guide to understanding OpenCV concepts and algorithms through real-world examples and activities. Through various projects, you'll also discover how to use complex computer vision and machine learning algorithms and face detection to extract the maximum amount of information from images and videos. In later chapters, you'll learn to enhance your videos and images with optical flow analysis and background subtraction. Sections in the Learning Path will help you get to grips with text segmentation and recognition, in addition to guiding you through the basics of the new and improved deep learning modules. By the end of this Learning Path, you will have mastered commonly used computer vision techniques to build OpenCV projects from scratch. This Learning Path includes content from the following Packt books: •Mastering OpenCV 4 - Third Edition by Roy Shilkrot and David Millán Escrivá •Learn OpenCV 4 By Building Projects - Second Edition by David Millán Escrivá, Vinícius G. Mendonça, and Prateek Joshi

Summary


In this chapter, we've learned about panorama creation. We've seen some of the underlying theory and practice in panorama creation, implemented in OpenCV's stitching module. We then turned our focus to creating an iOS application that helps a user to capture images for panorama stitching with overlapping views. Lastly, we saw how to invoke OpenCV code from a Swift application to run the stitching functions on the captures images, resulting in a finished panorama.

The next chapter will focus on selection strategies for OpenCV algorithms given a problem at hand. We will see how to reason about a computer vision problem and its solution offering in OpenCV, as well as how to compare competing algorithms in order to make informed selections.
