MACHINE LEARNING

Detailed explanation-1: -Because computerized facial recognition involves the measurement of a human’s physiological characteristics, facial recognition systems are categorized as biometrics.

Detailed explanation-2: -Face detection–also called facial detection–is an artificial intelligence (AI) based computer technology used to find and identify human faces in digital images.

Detailed explanation-3: -OpenCV uses machine learning algorithms to search for faces within a picture. Because faces are so complicated, there isn’t one simple test that will tell you if it found a face or not. Instead, there are thousands of small patterns and features that must be matched.

Detailed explanation-4: -Face recognition and Face detection using the OpenCV. The face recognition is a technique to identify or verify the face from the digital images or video frame. A human can quickly identify the faces without much effort. It is an effortless task for us, but it is a difficult task for a computer.
