(ZH) 一种基于3D指纹图像的性别识别方法及系统
Abstract
(EN)
The invention provides a gender identification method and a system based on 3D fingerprint images. The gender identification method based on 3D fingerprint images comprises the following steps: step S1, collecting fingerprint image data of a user based on optical coherence tomography; Step S2, extracting and training gender features in the fingerprint image data according to the fingerprint imagedata; 3, building a gender feature extraction classification model; Step S4, carrying out gender identification and prediction through the gender feature extraction classification model. 3-D fingerprint image are used for analyze and identifying gender features, It proves the existence of the internal gender characteristics of fingerprint, avoids the influence of the surface environment of fingerprint image on its identification, provides a gender discrimination scheme with higher accuracy and accuracy, and improves the anti-noise performance, which is of great significance to the gender classification of forensic anthropology, tracking and identification of unknown population and population census.

本发明提供一种基于3D指纹图像的性别识别方法及系统,所述基于3D指纹图像的性别识别方法包括以下步骤:步骤S1,基于光学相干断层扫描采集用户的指纹图像数据;步骤S2,根据所述指纹图像数据,提取并训练所述指纹图像数据中的性别特征;步骤S3,搭建性别特征提取分类模型;步骤S4,通过所性别特征提取分类模型执行性别的识别和预测。本发明利用3D指纹图像对性别特征进行分析和识别,证实了指纹内部性别特征的存在,避免了指纹图像的表面环境对其识别的影响,提供了更高正确率和精确度的性别判别方案,提高了抗噪性能,对于法医人类学的性别分类、跟踪与标识未知人群以及人口数据普查等具有非常重要的意义。
