Abstract

The invention relates to a fingerprint feature extraction method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a field fingerprint image; inputting the field fingerprint image into a fingerprint feature extraction model to obtain a feature extraction result output by the fingerprint feature extraction model, wherein the fingerprint feature extraction model is obtained by training based on a sample fingerprint image and detail point labels, wherein the fingerprint feature extraction model is used for extracting detail point information from the field fingerprint image and obtaining the feature extraction result based on the detail point information. According to the method and device, the electronic equipment and the storage medium provided by the embodiment of the invention, detail point information extraction is performed through the fingerprint feature extraction model, the feature extraction process can be simplified, and the model training speed and the feature extraction speed are increased while the accuracy is ensured.

Description

technical field [0001] The present invention relates to the technical field of fingerprint identification, and in particular, to a fingerprint feature extraction method, device, electronic device and storage medium. Background technique [0002] Since everyone's fingerprints are different, fingerprints can be used for identification purposes and have been used to solve criminal cases for centuries. With the development of computer and information technology, automatic fingerprint identification systems have been widely used all over the world. How to correctly extract the detailed feature points of fingerprints and achieve correct matching is the key to fingerprint identification technology. [0003] Currently, there are commonly used end-to-end neural networks that combine prior knowledge in the fingerprint field with the powerful expressive ability of neural networks to extract detail points of on-site fingerprints, such as FingerNet, which converts each part of the tradit...
