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.

Summary

In this chapter, we explored the basics of object segmentation in a controlled situation where a camera takes pictures of different objects. Here, we learned how to remove background and light to allow us to binarize our image better, thus minimizing the noise. After binarizing the image, we learned about three different algorithms that we can use to divide and separate each object of one image, allowing us to isolate each object to manipulate or extract features.

We can see this whole process in the following image:

Finally, we extracted all of the objects on an image. You will need to do this to continue with the next chapter, where we are going to extract characteristics of each of these objects to train a machine learning system.

In the next chapter, we are going to predict the class of any objects in an image and then call a robot or any other system to pick any...
