FACE RETRIEVAL METHOD AND DEVICE

A face retrieval method and device, relating to the fields of artificial intelligence and computer vision. The method comprises: obtaining a face image to be retrieved (S501); inputting the face image into a first feature extraction model to obtain a first face feature (S502); inputting the face image and the first face feature into a first feature mapping model for feature mapping to obtain a standard feature corresponding to the output first face feature (S503); and performing face retrieval on the face image according to the standard feature (S504). By splicing the features extracted from a plurality of feature extraction models, and using the spliced feature as the basis for constructing the standard feature, a face retrieval system can use the comprehensive effect of the plurality of feature extraction models to select an appropriate feature space, and improve the accuracy of face retrieval.
