What is face recognition?

Face recognition is a biometric identification technology based on face feature information. A series of related technologies, usually called portrait recognition and face recognition, are used to collect images or video streams containing faces, automatically detect and track faces in images, and then recognize the detected faces.

The face recognition system mainly includes four parts, namely, face image acquisition and detection, face image preprocessing, face image feature extraction, matching and recognition.

1, safe

Are you still worried that your identity information will be stolen? The appearance of face recognition technology completely solved this problem. Even if others get our personal information, they can't operate anything related to their own information. If face recognition fails, they can't operate. In this way, personal information is highly guaranteed, and people can rest assured of the convenience brought by face recognition.

Step 2 be quick

The efficiency of face recognition is 3-5 times higher than that of manual work. Now many supermarkets have opened face recognition payment. As long as you scan the goods independently, you can successfully pay through Alipay's face recognition, which not only saves human resources, but also greatly improves work efficiency. Although the manual payment window in the supermarket is larger than the face recognition window now, face recognition will be fully applied in the future.
