Problems solved by technology

[0003] It should be noted that when performing face recognition, if the collected recognition library pictures are photos of the recognizer many years ago, when the recognizer is re-recognized, the existing face recognition system does not consider the identity of the recognizer. Actual age, all recognizers are processed in various age groups, which cannot achieve effective recognition results, that is, when the recognized user and the face inventory have an age span, the existing face recognition system is not accurate

Embodiment 1

[0024] The invention provides a method for face recognition, such as figure 1 As shown, the method of face recognition may include:

[0025] Step S12, acquiring a face image.

[0026] Step S14, extracting feature information of the aforementioned human face image.

[0027] Specifically, in this solution, the recognition terminal can be used to collect the face image of the recognized user or receive the input of the face image of the recognized user, and then the recognition terminal can use the pre-built face recognition model to recognize the face image of the recognized user. User's face image for feature extraction.

[0028] Step S16, performing age assessment on the above-mentioned face image, and generating age information of the above-mentioned face image.

[0029] Specifically, in this solution, after the recognition terminal extracts the feature information in the face image of the recognized user, the recognition terminal can then evaluate the age of the recognize...

Embodiment 2

[0051] The present invention also provides a face recognition device, which is used to implement the face recognition method in Embodiment 1. It should be noted that the face recognition device can also be independently a face recognition terminal, or can be a A device running on a terminal or server, such as figure 2 As shown, the above-mentioned means may include:

[0052] The acquiring module 22 is configured to acquire a face image.

[0053] The extraction module 24 is configured to extract the feature information of the above-mentioned face image.

[0054] Specifically, in this solution, the acquisition module 22 can be used to collect the face image of the recognized user or receive the input of the face image of the recognized user, and then the extraction module 24 can use the pre-built face recognition model to Feature extraction is performed on the face image of the recognized user.

[0055] The assessment module 26 is configured to perform age assessment on the ...

Embodiment 3

[0079] Optionally, the solution of this application can also provide a face recognition system robust to age, which is a face recognition system based on a deep learning model, such as image 3 As shown, the face recognition system can include an image data input module 30, a hidden layer 1, a hidden layer 2, a hidden layer 3, a hidden layer 4, a face recognition feature layer 34, an age evaluation feature layer 36, an age evaluation module 38 and Face recognition module 40. The hidden layer 32 may be a convolution operation and downsampling operation module. The face recognition feature layer 34 is used for face recognition to describe the features of the face. The age assessment feature layer 36 is the feature description of the face used for age assessment. The information of the age assessment feature layer 36 is shared with the face recognition module 40, and the result of the age assessment is also fed back to the face recognition module 40. The face recognition module...

Abstract

The invention discloses a method and a device for human face identification. The method comprises the steps of acquiring a human face image; extracting characteristic information of the human face image; performing age assessment on the human face image to generate age information of the human face image; and performing human face identification on the human face image according to the characteristic information and the age information. With the method and the device for human face identification, the technical problem of inaccurate identification of an existing human face identification system in the case that an age span exists between an identified user and a human face database is solved.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular to a face recognition method and device. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. At present, face recognition has begun to be applied in many fields, such as access control, device login, airport, and public area monitoring. [0003] It should be noted that when performing face recognition, if the collected recognition library pictures are photos of the recognizer many years ago, when the recognizer is re-recognized, the existing face recognition system does not consider the identity of the recognizer. Actual age, all recognizers are processed in various age groups, which cannot achieve effective recognition results, that is, when the recognized user and the face database have an age span, the existing face recognition system is not accurate .
