Design of Face Recognition Alarm System Based on LBPH Algorithm

Keeping up with the advent of the wave of the network big data information age, there are more and more security risks in information security. This paper focuses on the alarm system of face recognition, using Python, OpenCV, HOG directional gradient histogram and QT interface. The content required for face recognition by electronic machinery and computer machines was analyzed. The HOG directional gradient histogram was used to recognize the face, and the feature vector was converted into face data. It realizes the function of timely alarm at the first time after face recognition; It achieves the purpose of face recognition and personnel identity authentication and timely alarm when non-insider personnel are detected.
