Embodiment Construction

[0047] The low-power face recognition method according to a preferred embodiment of the present invention is based on an access control unit with a face acquisition device, including:

[0048] (1) Obtain the first face image by the access control unit, the first face image includes a first part and a second part, wherein the data volume of the first part is at most one-third of the data volume of the second part;

[0049] (2) performing a first local analysis on the first part of the first face image to obtain a first local analysis result;

[0050] (3) performing a first remote analysis on the second part of the first face image to obtain a first remote analysis result;

[0051] (4) When the first local analysis result satisfies the first eigenvalue less than the predetermined value, the second face image is obtained by re-detecting the face after the access control unit is heated up, and simultaneously detecting the difference between the finger to be recognized and the reco...

Abstract

To improve recognition accuracy upon real human body characteristic parameters, and improve recognition security of door access units, the invention discloses a low-power consumption human face recognition method. On the basis of a door access unit with a human face acquisition device, recognition and comprehensive judgment are carried out through a local part and a remote part, the situation thata fake medium cannot be recognized is reminded, the situation that recognition on a real medium which can be recognized is successful or failed is reminded, influence of null shift of a recognition sensor of the door access unit self in the heating process is not eliminated in the recognition process, but the influence is actively taken into account and comparison of an experience calculation mode of square root calculation is carried out in calculation of detection results of two times. Therefore, the influence can be ignored in analysis and calculation, that is, the influence can be eliminated in square root calculation. Tests show that the recognition accuracy upon fake mediums to be recognized can be increased by about 40%.

Description

technical field [0001] The invention belongs to the technical field of security and image processing, and in particular relates to a face recognition method with low power consumption. Background technique [0002] Biometrics is a new identity authentication technology. In real life, everyone has unique biological characteristics that are different from other people. With the development of computer technology, people can extract their own biometric information, such as face, face, finger veins, iris, voiceprint, etc. This technology that relies on people's physical characteristics for identification is called biometric technology. [0003] Face recognition technology is a kind of biometric identification technology, which has achieved rapid development in recent years due to its advantages of convenience, speed and accuracy. The input of the face recognition system is generally a face image containing the identity to be detected, and several face images of known identiti...
