Fingerprint image compositing method and associated apparatus |
摘要 |
A method and apparatus generates fingerprint data for a fingerprint area larger than a sensing area of a fingerprint sensor. A fingerprint of a user is enrolled by generating fingerprint data sets responsive to placing a finger of a user on a sensing area of the fingerprint sensor a plurality of times with the finger being slightly repositioned on successive placements. The method also includes processing the fingerprint data sets to generate a composite fingerprint data set over an area of the fingerprint larger than the sensing area of the fingerprint sensor. The method may also be extended to the matching of a new fingerprint to an enrolled fingerprint based upon at least one sensing of the new fingerprint and the composite fingerprint data sets. A plurality of fingerprint feature location data sets may be generated and include at least one of a plurality of minutiae location data sets, a plurality of skin pore location data sets, and a plurality of feature location data sets relating to fingerprint ridge flows.
