Problems solved by technology

However, in this way of establishing sub-databases, there is the possibility of duplication of face data in different sub-databases. When face registration and face update are performed in different sub-databases, repeated extraction of face features will cause a waste of computing resources. waste

Embodiment 1

[0022] figure 1 It is a flow chart of a face retrieval method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of face retrieval by establishing a feature database and a comparison database. This method can be executed by a face retrieval device , the device can be implemented by software and / or hardware, and is generally integrated in a server.

[0023] Such as figure 1 As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0024] S110. When detecting the face registration request of the user to be registered, determine an identity matching the user to be registered.

[0025] Among them, the user to be registered is a user who registers identity information, face information, etc. through a client terminal with a face retrieval function. The face registration request is a request sent by the user to be registered through the client with the face retrieval func...

Embodiment 2

[0039] figure 2It is a flow chart of a face retrieval method provided by Embodiment 2 of the present invention. On the basis of the above embodiments, the embodiment of the present invention further improves the process of face retrieval according to the face feature values ​​in the comparison database. , and added the steps of establishing a feature database, comparing the steps of updating the facial feature values ​​in the database, the steps of user registration to the custom database, and the steps of updating the face feature values ​​in the custom database.

[0040] Correspondingly, such as figure 2 As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0041] S210. Establish a feature database, the feature database includes multiple user IDs, face images of each user, and face feature values ​​obtained by feature extraction from the face images of each user.

[0042] In the embodiment of the present ...

Embodiment 3

[0083] image 3 It is a schematic structural diagram of a face retrieval device in Embodiment 3 of the present invention. The device can be integrated in a server. The device includes: a user identity identification determination module 310 to be registered, a feature database face feature value determination module 320, and a human face retrieval device. Face retrieval module 330 . in:

[0084] The identity identification module 310 of the user to be registered is used to determine the identity identification matched with the user to be registered when the face registration request of the user to be registered is detected;

[0085] Feature database face feature value determining module 320, for determining the face feature value matching with the user to be registered in the feature database according to the identity mark matched with the user to be registered;

[0086] The face retrieval module 330 is used to determine the comparison database matching the user to be regist...

Abstract

The invention discloses a face retrieval method and device, computer equipment and a storage medium. The method comprises the steps that when a face registration request of a to-be-registered user is detected, an identity label matched with the to-be-registered user is determined; determining a face feature value matched with the to-be-registered user in a feature database according to the identity label matched with the to-be-registered user; and determining a comparison database matched with the to-be-registered user, and storing the face feature value matched with the to-be-registered user into the comparison database so as to perform face retrieval according to the face feature value stored in the comparison database. By using the technical scheme of the invention, repeated extraction of face features can be avoided, and waste of computing resources is reduced.

Description

technical field [0001] Embodiments of the present invention relate to data processing technology, and in particular to a face retrieval method, device, computer equipment and storage medium. Background technique [0002] Face retrieval refers to inputting one or a series of face images with undetermined identities, searching in several face images with known identities or corresponding face feature databases, and outputting a series of similarity scores and faces to be recognized. identity. Face retrieval has a wide range of applications in scenarios such as customer identification at outlets, facial recognition payment, attendance management, and meeting sign-in. [0003] In the prior art, in order to improve the efficiency of face retrieval, sub-databases such as temporary databases, two-level databases, and regional databases are usually established to reduce the number of faces that need to be compared during face retrieval. However, in this way of establishing sub-dat...
