Face Detection

A computer vision technology that identifies and locates human faces within digital images or video frames, typically providing bounding box coordinates around each detected face. Face detection serves as the foundation for more advanced tasks like face recognition (identifying who the person is), head pose estimation, and distance estimation. In assistive technology for blind users, face detection enables wearable devices to alert users to the presence of nearby people and can be personalised through teachable interfaces where users provide photos of family and friends so the system can recognise and name them.
