Face detection

Face detection is a computer technology used to detect and identify human faces in digital images or videos. It involves using algorithms to detect the location, size, and orientation of each face within an image or video. Eye detection is a specific form of face detection that focuses on identifying the location and presence of eyes within an image or video. This can be useful for applications such as gaze tracking or identifying drowsiness in drivers. Smile detection, on the other hand, involves identifying whether a person in an image or video is smiling or not. This can be useful for applications such as market research or emotion recognition in social interactions. Both eye and smile detection are often used in conjunction with face detection algorithms
