How can I identify a face from a picture?

You can detect the faces in the image using method detectMultiScale() of the class named CascadeClassifier. This method accepts an object of the class Mat holding the input image and an object of the class MatOfRect to store the detected faces.

Can Google Recognise a face?

With Nest Aware, you can use familiar face detection¹ to teach your Google Nest camera to recognize faces of people that you know, and notify you when it detects people it doesn't recognize. Over time, facial recognition becomes more accurate at determining familiar faces and can send you more helpful alerts.

Can AI detect faces?

Some facial recognition systems are equipped with artificial intelligence that can learn to identify individuals even if their appearance has changed, such as if they've grown a beard or gained weight.
