Claim 5:
6. The device of claim 5, wherein the processor is configured to:
input the finger template image and the non-finger image into the data feature augmentation network to generate a generation feature of the original occluded image;
input the original occluded image into a feature network to extract an original feature of the original occluded image, the occluded-image detection model comprising the feature network;
input the generation feature and the original feature of each original occluded image into a discriminative network for training;
obtain a loss function of the data feature augmentation network and a loss function of the discriminative network in each round of training; and
determine that the training of the data feature augmentation network is finished when both the loss function of the data feature augmentation network and the loss function of the discriminative network converge.
