Three dimensional minutiae extraction in three dimensional scans

摘要

A system and method extract a plurality of three dimensional identification minutiae from a three dimensional image of a biometric identification feature. The extracted three dimensional identification minutiae from the three dimensional image may be compared to one or more sets of three dimensional identification minutiae to determine an identification and/or confirm an identification. In a preferred embodiment, the system and method extract three dimensional identification minutiae from a three dimensional image of a fingerprint, and compare the extracted three dimensional identification minutiae from the fingerprint to one or more sets of three dimensional identification minutiae associated with previously classified fingerprints to determine and/or confirm an identification.

主权项

1. A method of analyzing a three dimensional image of a biometric identification feature, the method comprising:
receiving the three dimensional image; analyzing the three dimensional image in a three dimensional space with at least one hardware based processor to identify at least one identification minutiae of the biometric identification feature in the three dimensional image based at least in part on a three dimensional characteristic determined from analyzing the three dimensional image in the three dimensional space; and generating an identification minutiae dataset based on the identified identification minutiae.
