Embodiment 1

[0035] Such as figure 1 Shown, a kind of adaptive face recognition method, this method comprises the following steps:

[0036] Step S101: Enter the basic information of the face user, collect a plurality of face images of the face user, and extract face features from them as face feature templates, and save the basic face user information and face feature templates to Face user information database;

[0037] Specifically, input the basic information such as the number, name, address, and contact information of the face user for user retrieval or voice broadcast or display after user identification is successful; continuously collect the face images of the registered users, and each user needs to Collect multiple face images from different angles; for each face image collected, use the Garbor wavelet feature method and the local binary pattern (LBP, local Binary Patterns) method to extract a set of face features F m , and respectively calculate the facial features and the ext...

Embodiment 2

[0050] Such as figure 2 Shown, a kind of adaptive face recognition method, this method comprises the following steps:

[0051] Step S201: Enter the basic information of the face user, collect a plurality of face images of the face user, and extract face features from them as face feature templates, and save the basic information of the face user and the face feature template to Face user information database.

[0052] Specifically input the basic information such as the number, name, address, and contact information of the face user, which is used for user retrieval or voice broadcast or display after the user identification is successful; continuously collect the face images of the registered users, and each user needs to collect Multiple face images from different angles; each face image is collected, using the Garbor wavelet feature method and the LBP (local Binary Patterns) method to extract a set of face features F m , and respectively calculate the facial features and...

Abstract

The embodiment of the invention discloses self-adapting face identification method and device relating to the field of face identification. The self-adapting face identification method comprises the following steps of: typing in the basic information of a face user; acquiring a plurality of face images of the face user and respectively extracting the face features from the face images to serve as a face feature template; saving the base information of the face user and the face feature template to a face user information base; extracting the face features from the acquired face images, and carrying out comparison identification with the face feature template in the face user information base; if the identification passes, further judging whether the face features meet the preset self-adapting demands or not; and if yes, updating the face feature template in the face user information base to complete the face feature self adapting. The method effectively eliminates the influence generated on the face identification effect because the face features slowly change with the changes of ages, beards and the like, thereby improving the identification speed and accuracy.

Description

technical field [0001] The invention relates to the field of biological feature recognition, in particular to the field of face recognition, and in particular to an adaptive face recognition method and device. Background technique [0002] At present, biometrics as identity authentication has become a common phenomenon, and the convenient, quick, and non-contact authentication method is popular among the public. Face has the advantages of rich features and convenient collection. As a non-contact identity authentication method, face recognition has broad application prospects in customs, finance, security and other fields. [0003] The commonly used workflow of face recognition as an identity authentication method is to first register the user's face feature information and save it in the face database. When identity authentication is required, the user performs face recognition and extracts the user's current face. The feature information is compared with the face feature i...
