基于指部关联特征的多模态图像采集系统
Multimodal Image Acquisition System Based on Finger Correlation Features
摘要
Abstract
To avoid the low security and instability of single biometric authentication,a multimodal image acquisition system based on finger features is designed to realize the time-sharing collecting the fingerprint,finger knuckle and finger-vein images through a dual-band camera. Fingerprint and finger knuckle images are acquired by non-contact reflection way. The single light source and reflection mirror is adopted while collecting finger-vein image. The near-infrared LED light source position and angle can be adjusted according to the finger-vein image quality assessment. The weights are adjusted based on the information contents of three features. Actual test results show that multimodal image acquisition system has distinctive advantages compared to single-mode image acquisition system,which was based on fingerprint or finger-vein. In proposed system, authentication passing rate can reach 99. 1% and false accept rate is 0. 000 1% without rejection registration.关键词
