Face Recognition Attendance Access Control Features

When it comes to identification, people are more likely to think of swiping and fingerprinting. In addition to these two identification technologies, they have to take cards and extend their fingers in any situation. With the development of science and technology, their security performance is no longer reliable: the former "recognizes the card does not recognize people", and Cards are easily copied; for the latter, the applicability of fingerprinting is not strong. According to statistics, about 5% of people cannot use fingerprint recognition. For example, fingerprints and shallow ladies, as well as laborers who often work hands, fingerprints will be polished or blurred, and fingerprint recognition as a contact recognition technology in recent years It is easy to be copied using the fingerprint sleeve of silica gel, and the security is highly questioned.

Face recognition attendance access control has the characteristics of non-contact, good visual and user acceptance. It first analyzes and extracts face features and stores them in the database, ie face registration; then when used, extracts face features again and compares them with the features in the database. Usually, when two templates are compared At this point, if the degree of similarity exceeds the system's pre-set threshold, the system considers the comparison successful—these two templates are from the same person.

Although face recognition attendance access control has received much attention, because face images are influenced by factors such as age, posture, expression, lighting, etc., they have the feature of “one person one thousand face”. Therefore, face recognition technology is extremely challenging and is considered to be challenging. It is one of the most difficult research topics in the field of biometrics.

The current face recognition attendance access control is divided into two categories: two-dimensional face recognition and three-dimensional face recognition. The two-dimensional face recognition is based on the face plane image, but actually the face itself is three-dimensional. The face plane image is only a projection of a three-dimensional face on a plane. In this process, part of the information is bound to be lost. The further improvement of the two-dimensional face recognition performance has been adversely affected by factors such as ambient light, posture, and expression. Three-dimensional face recognition is based on three-dimensional face images. Theoretically speaking, it possesses some technical advantages of three-dimensional image information. However, there are always collection devices that are expensive, the acquisition system is complex, and the storage degree is high. The face reconstruction algorithm is complex and the recognition speed is relatively high. Slow and other shortcomings.
