Embodiment Construction

[0030] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, this example provides a gender identification method based on a 3D fingerprint image, including the following steps:

[0032] Step S1, collecting fingerprint image data of the user based on optical coherence tomography;

[0033] Step S2, extracting and training gender characteristics in the fingerprint image data according to the fingerprint image data;

[0034] Step S3, building a gender feature extraction classification model;

[0035] Step S4, performing gender identification and prediction through the gender feature extraction classification model.

[0036] In step S1 described in this example, the fingerprint images of OCT (optical coherence tomography) are collected as training data, preferably at least 400 fingerprint images of the same finger of the same user are collected as fingerprin...

Abstract

The present invention provides a gender identification method and system based on a 3D fingerprint image. The gender identification method based on a 3D fingerprint image includes the following steps: step S1, collecting user fingerprint image data based on optical coherence tomography; step S2, according to the The fingerprint image data, extracting and training the gender feature in the fingerprint image data; step S3, building a gender feature extraction classification model; step S4, performing gender identification and prediction through the gender feature extraction classification model. The present invention uses 3D fingerprint images to analyze and identify gender characteristics, confirms the existence of gender characteristics inside the fingerprint, avoids the influence of the surface environment of the fingerprint image on its identification, and provides a gender discrimination scheme with higher accuracy and accuracy. The anti-noise performance is improved, which is of great significance for gender classification of forensic anthropology, tracking and identification of unknown populations, and census of population data.

Description

technical field [0001] The invention relates to a gender identification method, in particular to a gender identification method based on a 3D fingerprint image, and to a gender identification system using the gender identification method based on a 3D fingerprint image. Background technique [0002] As the main biological feature of fingers, fingerprints have several ideal characteristics such as universality, distinctiveness, permanence, collectability, acceptability and anti-circumvention, and are widely used in personal identification systems. The existing biometric identification based on traditional 2D fingerprint images makes it impossible or extremely difficult to form a traditional reference 2D fingerprint pattern when the surface of the fingertip is severely damaged or there is oil or sweat. [0003] With the maturity of OCT (Optical coherence tomography, optical coherence tomography) imaging technology, 3D-image analysis of fingerprints has been realized. On the o...
