Problems solved by technology

Now commonly used feature extraction methods include principal component analysis (referred to as PCA algorithm), local binary pattern algorithm (referred to as LBP algorithm), etc., but these methods have limitations, usually for the feature extraction of frontal faces, but for non- For the feature extraction of frontal faces, these algorithms will fail, and the effectiveness of the face feature extraction model directly affects the speed of classification and recognition performance

Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing.

[0042] In this example, if figure 1 As shown, the multi-angle-based face recognition model training and testing system of the present invention includes four core modules in concrete implementation: a face sample database angle division module, a multi-angle training sample combination module, and a loss function calculation combined with face angles module, multi-angle face recognition model test module.

[0043] The angle division module of the face sample database first selects P pieces of continuous angle-changing photos of each face of N different people as a group of multi-angle photo sequences of faces, and rotates the face photos to be trained according to left-right rotation and up-down rotation The two direction angles are divided, the range of left and right rotation angles [-α, α] = [-75°, 75°], the range of up and down rotation angles [-β, β] = [-45°, 45°], ea...

Abstract

The invention discloses a multi-angle face recognition model training and testing system which comprises a face sample library angle division module, a multi-angle sample combination training module, a face angle loss function calculation module and a multi-angle face recognition model testing module. According to the invention, the system is applicable to multi-angle face recognition; the problem of poor non-positive-face recognition effect in a face recognition process can be overcome; and the accuracy of non-positive-face recognition in the face recognition process is improved.

Description

technical field [0001] The invention belongs to the field of deep learning for extracting facial features by a deep neural network, relates to technologies such as neural networks and pattern recognition, and in particular relates to multi-angle-based face recognition model training and testing methods. Background technique [0002] Face recognition technology is a research hotspot in artificial intelligence and pattern recognition today, and it is a biometric recognition method that automatically identifies people based on their facial features. It has a wide range of applications in access control, judicial applications, e-commerce and video surveillance and other fields. [0003] With the development of science and technology, the scope of application of face recognition has been continuously expanded, gradually extending from the field of public security criminal investigation to the civilian market, such as anti-theft doors with face recognition functions, face recognit...
