Claim 9:
10. The face search device according to claim 3, wherein the second feature mapping model comprises an image branching module, a feature branching module, and a synthesis module, and wherein the training the second feature mapping model based on the face sample image, the first face sample feature, and the target feature corresponding to the face sample image to obtain the first feature mapping model comprises:
inputting the face sample image into the image branching module to output a fourth face sample feature;
inputting the first face sample feature into the feature branching module to output a fifth face sample feature, wherein the first face sample feature is extracted from the face sample image by using the first feature extraction model;
inputting both the fourth face sample feature and the fifth face sample feature into the synthesis module, to obtain a standard feature corresponding to the first face sample feature; and
training the image branching module, the feature branching module, and the synthesis module based on the face sample image, the first face sample feature, the standard feature corresponding to the first face sample feature, and the target feature corresponding to the face sample image, to obtain the first feature mapping model.
