Abstract

The invention discloses a method for identifying human faces in real time under multi-person dynamic environment, and belongs to the technical field of electronic identification. The method comprises the following steps of: (1) initializing an image; (2) detecting a human face; (3) extracting the facial feature of the human face; (4) registering human face information; (5) acquiring a video image sequence; (6) detecting the human face; (7) extracting the facial feature of the human face; (8) identifying the human face; (9) acquiring the current human face information sequence; (10) acquiring the video image sequence; (11) detecting the human face; (12) tracking the human face; and (13) acquiring the current human face information sequence. The method has the advantage that features required by the detection, tracking and identification of the human face are utilized repeatedly and are processed progressively, so that calculated amount is saved greatly and high speed and high accuracy are realized.

Description

technical field

[0001] The invention relates to a face recognition method, in particular to a real-time face recognition method in a multi-person dynamic environment, and belongs to the technical field of electronic recognition. Background technique

[0002] Facial recognition technology is often used in security and surveillance systems, for example to determine whether a person can be authorized or enter a particular system. At present, face recognition technology usually needs to provide a complete and clear face, and the recognition process takes a long time, so that a person needs to wait for a long time before the face recognition system obtains the recognition result. Such a facial recognition system can only be used when the user and the system fully cooperate. However, in the actual monitoring system, the user will not actively cooperate with the face recognition system. Therefore, it will often occur that many people enter the monitoring range at the same time, t...
