Embodiment 1

[0036] Such as figure 1As shown, the present invention discloses a face recognition system, comprising: a face acquisition module, a face feature extraction module, a face recognition module and a face index module; A face image, and the face image is input into the face feature extraction module; the face feature extraction module is used to extract the face feature data of the person to be identified from the face image, and the The face feature data of the person to be identified is input to the face recognition module; the face recognition module is used to combine the face feature data of the person to be identified with the known identity samples stored in the face index module The data is matched by similarity, and the identity of the person to be identified is determined according to the result of the similarity matching; the face feature extraction module is based on a lightweight neural network, and the GDConv Block (GlobalDepthwise Convolution Block, global depth vo...

Embodiment 2

[0043] Embodiment 2 is a preferred embodiment of Embodiment 1. It differs from Embodiment 1 in that the structure and functions of the face recognition system are expanded, and the steps of the face recognition method are refined:

[0044] In this example, if figure 2 As shown, a face recognition system is disclosed, including:

[0045] A video acquisition module, which collects the video sequence of the identified person through the camera, and inputs the video sequence into the face detection module;

[0046] A face detection module, the face detection module runs in the ARM, directly detects the face from the video sequence, that is, detects the face image of the person to be identified from the video sequence, and inputs the face image The human face feature extraction module;

[0047] The face feature extraction module extracts the face feature data of the person to be identified from the face image, and inputs the face feature data of the person to be identified to th...

Abstract

The invention discloses a face recognition system and method. The face recognition system comprises a face acquisition module, a face feature extraction module, a face recognition module and a face index module. The face acquisition module is used for acquiring a face image of a person to be recognized; the face feature extraction module is used for extracting face feature data of a person to be recognized from the face image; the face recognition module is used for carrying out similarity matching on the face feature data of the person to be recognized and the sample data of the known identity stored in the face index module; the face feature extraction is used for replacing a deep neural network formed by a global average pooling layer of the lightweight neural network with the GDConv Block based on a lightweight neural network; the neural network is deeper, stronger in generalization ability and better in robustness, the face feature data of the person to be recognized can be rapidly extracted on the basis of ensuring the accuracy, and then the identity of the person to be recognized can be rapidly and accurately recognized.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to a face recognition system and method. Background technique [0002] Face recognition technology is a very important identity authorization technology. In recent years, this technology has been increasingly used in mobile devices and embedded devices based on ARM (Advanced RISC Machines, a 32-bit reduced instruction set processor architecture) chip Get applications in, such as device unlocking, application login, mobile payment and so on. Some mobile devices and embedded devices have been equipped with face recognition technology, such as smartphone unlocking, high-speed rail station entrance gates, and community face access control, all of which must be run offline. In order to obtain a better user experience with limited computing resources, face recognition models need to be deployed locally on these devices, which imposes higher requirements on the accuracy and performance of ...
