A New Method for Real-Time Hybrid Fingerprint Identification
A real-time optical/digital hybrid system for fingerprint identification based on the 1-f joint transform correlation is developed. The fingerprint is read by using the total internal reflection property of a prism and is pre-processed by two-order differenciation algorithm. The joint transform power spectrum can be binazed visually by adjusting the Monitor. This system is demostrated, and the experimental results show that it performs well.
