摘要
A pattern identification technique using the wavelet matched filter (WMF) based on the photorefractive (PR) crystal has been proposed. The essential merit of using the WMF is that it offers better signal discrimination than the conventional matched filter (CMF). Since a large number of WMFs can be synthesized in a PR crystal, fingerprint identification was chosen as the application. Simulated and experimental results are provided.
