Diving deep into the Face API
The Face API has two main features. The first one is face detection, and the other is face recognition.
Face detection allows one to detect up to 64 faces in one image. We have already seen the basic usage. The features of face recognition are implied in its name. Using it, we can detect if two faces belong to the same person. We can find similar faces, or one in particular, and we can group similar faces.
