Chapter 15: Recognition with Vision Framework

The Vision framework has been available to developers for a few years now. Apple has been introducing better and better features for it, from text recognition to image recognition. On iOS 14, Vision comes with more improvements to text recognition and other existing functions, but it also allows developers to perform two different actions: hand and body pose recognition. The possibilities that these new features open up for developers are limitless! Just think about gym apps, yoga apps, health apps, and so on.

In this chapter, we are going to learn about the basics of the Vision framework and how to use the new advancements in text recognition. We will also learn about the new hand landmark recognition, building a demo app that can detect the tips of the four fingers and the thumb. The chapter code bundle also provides a similar example demonstrating body pose recognition. We will discuss these topics in the following sections:
