Summary
In this chapter, we learned about the importance of keypoints and why we need them. We discussed various algorithms for detecting keypoints and computing feature descriptors. We will be using these algorithms in all the subsequent chapters in various contexts. The concept of keypoints is central to computer vision, and plays an important role in many modern systems.
In the next chapter, we are going to discuss how to stitch multiple images of the same scene together to create a panoramic image.
