Abstract: A fingerprint template updating method and device is provided. The fingerprint template updating method includes: in response to an acquired current fingerprint matching one of at least one fingerprint template, determining whether to update the at least one fingerprint template using the current fingerprint based on a matching status of a first number of fingerprints acquired prior to the current fingerprint and/or a second number of fingerprints acquired after the current fingerprint.

Abstract: A fingerprint segmentation method and device is provided. The fingerprint segmentation method may include dividing a fingerprint image into a plurality of sub-images, pooling each sub-image to acquire a feature map of the fingerprint image, and segmenting the feature map based on a region growing algorithm to acquire a fingerprint region in the fingerprint image.

Abstract: The present disclosure relates to a fingerprint identification method, device, an electronic apparatus and a storage medium. The fingerprint identification method includes: capturing a fingerprint by a fingerprint sensor, identifying matching pairs of minutiae between the captured fingerprint and a reference fingerprint; calculating a first matching result based on the minutia matching pairs; identifying minutia surrounding features for each minutia of the captured fingerprint in the minutia matching pairs; determining, for each minutia in the minutia matching pairs, whether the minutia surrounding features of the captured fingerprint match with minutia surrounding features of the reference fingerprint; calculating a second matching result based on the determination; and generating an identification result based on the first matching result and the second matching result.
