Abstract

The invention provides a method for constructing and training a human face identification feature extraction network. The method comprises the steps of constructing a feature extraction network and a metric learning dimension reduction network, wherein an output of the feature extraction network is an input of the metric learning dimension reduction network; training the feature extraction network based on all sample sets to output feature sets; screening the feature sets by utilizing semantic sampling to obtain a pure sample set; and training the metric learning dimension reduction network based on the pure sample set. Through a natural human face identification network constructed by the method, the feature representation capability can be improved, so that feature information in data can be fully mined and an original human face picture can be accurately identified.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a method for constructing a face recognition network, specifically a method for constructing and training a face recognition feature extraction network. Background technique [0002] Face recognition has always been a hot topic in computer vision. Compared with traditional biometric identification such as iris recognition and fingerprint recognition, face recognition does not need to use special media to collect data, and only the image data or pictures obtained by the most common camera can complete the recognition task. This makes face recognition have a wider range of application scenarios than iris recognition and fingerprint recognition. As a kind of biometric identification, face recognition is mostly used in security, identity authentication and other fields. With the continuous development of society and the continuous advancement of science and techno...
