Abstract

The present disclosure relates to the technical field of signal processing, and discloses a method for recognizing fingerprint medium consistency, comprising: obtaining current to-be-verified fingerprint data; searching for target fingerprint template data matching the current to-be-verified fingerprint data in a registered fingerprint template dataset; searching for a target feature descriptor corresponding to the target fingerprint template data in a template feature descriptor set; and generating a verification feature descriptor using the pre-trained feature extraction network based on the current to-be-verified fingerprint data, and generating a current medium consistency probability of a verification fusion feature using a pre-trained feature fusion classification network based on the verification feature descriptor and the target feature descriptor. The present disclosure improves the accuracy of fingerprint classification and recognition.
