Abstract:
A method for fingerprint image recognition according to an embodiment includes ranking a plurality of target feature points acquired from a target fingerprint image according to a feature point attribute, comparing the ranked plurality of target feature points with a plurality of reference feature points in a reference fingerprint image to form an entropy map, and determining whether the target fingerprint image matches the reference fingerprint image according to the entropy map, wherein the entropy map indicates similarity between the target fingerprint image and the reference fingerprint image. The solution of the present disclosure makes full use of the acquired image information of the target fingerprint image for fingerprint recognition, thereby significantly improving the accuracy and effectiveness of fingerprint recognition.
