Joint transform correlator for an optical face recognition system

  • 4 Accesses

  • 4 Citations


An opto-electronic hybrid face recognition system based on real-time joint transform correlation using two types of liquid crystal spatial light modulators is proposed. The novel digital pre-processing to improve the tolerance was confirmed experimentally by face recognition from 100 references.
