We're going to see how we can perform facial recognition with dlib with a relatively small amount of code. Facial recognition here means that we're going to look at an image and see whether or not this person is the same as the person in a different image. We're going to keep it simple here and just compare two faces to see whether they're the same, but this can easily be generalized, as we'll see later.
