Facial recognition:
Face recognition is a biometric identification technology based on face feature information. The video camera or video stream containing faces is used to automatically detect and track faces in the images, and then a series of face-related technologies are carried out on the detected faces, which are usually also called face recognition and face recognition.
Face recognition in a broad sense actually includes a series of related technologies to build a face recognition system, including face image acquisition, face location, face recognition preprocessing, identity confirmation and identity search. Face recognition in a narrow sense refers to the technology or system of identity confirmation or identity search through faces. ?
Biometric features studied by biometric technology include face, fingerprint, palm print, iris, retina, voice (voice), body shape, personal habits (such as typing strength and frequency, signature) and so on. The corresponding recognition technologies include face recognition, fingerprint recognition, palmprint recognition, iris recognition, retina recognition and voice recognition (voice recognition can be used for identity recognition and voice content recognition. ?
