Compared with other biometric technologies, face recognition has the advantages of non-contact, non-intrusiveness, perfect hardware foundation, and scalability. This article mainly analyzes the face recognition industry with you, enjoy~ 1. Overview of face recognition Biometrics refers to the identification technology fax number database that relies on the physical characteristics of the human body for identity verification . At present, the more mainstream identification technologies are: face recognition, fingerprint recognition, iris recognition, and voice recognition. Face recognition is a kind of biometric identification technology based on human facial feature information. A camera or camera is usually used to capture images or video streams containing faces, and automatically detect and track faces in the images.
The face recognition system mainly includes four components, namely face image acquisition and detection, face recognition preprocessing, face image feature extraction, and matching and recognition. Compared fax number database with other biometric technologies, face recognition has the advantages of non-contact, non-intrusiveness, perfect hardware foundation, and scalability. The uniqueness of fingerprint recognition is relatively strong, and the collection cost is low, but fingerprints can be copied by fingerprint stickers, fingerprint films, etc., and the contact and intrusion are relatively strong.
Compared with face recognition, the contact and intrusion are lower; iris recognition is the most accurate. , but the collection cost is very high, the recognition efficiency is low, and the contact and intrusion fax number database are also strong. Compared with face recognition, the collection cost is low and the recognition efficiency is high; the voice recognition collection cost is low, but the voice has variability, and the face Compared with its recognition, recognition efficiency is high. The principle of face recognition technology is basically three steps:
