| Title: |
Composite Filter for VanderLugt Correlator |
| Published: |

| Abstract: |
This paper will examines the use of composite filters for improving the effectiveness of a Vanderlugt correlator when used for fingerprint identification. A digital simulation, which accounts for noise sources in the optical setup, is used to design and test composite matched spatial filters. Results are presented for a real time video image database containing 10 seconds of video from 200 fingers. Using the composite matched spatial filter, the Vanderlugt correlator is getting 70% correct indentifications with no false positives. |
