Patent ID: 8872909

Claim:
A system for extracting finger vein and finger texture images from a finger of a person at the same time, the system comprising: an image capture device configured to capture a plurality of images of at least one finger in a contactless manner, where the plurality of images comprise at least one finger vein image acquired utilizing a near infrared illumination and at least one finger texture image acquired utilizing a visible light illumination; a feature extraction module configured to: extract unique finger vein features and finger texture features from the plurality of captured images, wherein the finger texture features comprise at least one fingerprint image; compute a finger texture matching score from the finger texture features, and a finger vein matching score from the finger vein features; and combine the finger vein and finger texture matching scores to generate a combined matching score by computing for the combined matching score S c such that: S c =(ε+ s v ) w *(ε+ s t ) (2−w) where s v and s t are the finger vein and finger texture matching scores, respectively, and ε and w are empirically determined constants; and a processing module configured to normalize the plurality of captured images and integrate the extracted finger vein features and finger texture features.
