BIOMETRIC RECOGNITION

摘要

A fused image of the person's hand is accessed, the fused image having been generated using a segmented graylevel image and a segmented color image. The hand in the fused image is identified. One or more finger tips and one or more finger valleys in the fused image are identified. One or more fingers of the hand are segmented, based on the identified finger tips and finger valleys. The one or more fingers of the hand are labeled. One or more features for each finger of the hand are determined.

主权项

1. A biometric authentication system comprising:
a data storage system configured to maintain, for a group of people, biometric data that includes respective collections of features for persons in the group of people, each collection of features describing characteristics of a finger of a hand of a person; and a biometric verification system that includes at least one processor that is configured to interact with a computer storage medium to perform operations comprising: accessing an image of a first hand associated with a person, the image having been captured by an image capture device; determining, from a fused image of the first hand and for each finger of the first hand, a respective collection of features, each feature describing a characteristic of the finger, wherein the fused image of the first hand is generated based on a comparison of first and second segmented images of the first hand; accessing, from the data storage system, for each finger of a second hand, a respective collection of matching features, each feature describing a characteristic of the finger; generating, based on a comparison of collections of features that correspond to fingers of the first hand and collections of matching features that correspond to fingers of the second hand, a similarity score that measures a similarity between the first hand and the second hand; and outputting a result based on the similarity score.
