| Research Abstract |
We developed a face recognition system with an optical image correlator using a holographic memory. The image correlator based on the phase-only correlation offers high speed processing and low recognition error rate. The information of the facial database is protected by using a phase code encryption. The facial image rotated to a position in front of the virtual camera is reconstructed automatically with computer graphics using three-dimensional facial data provided by the stereovision technology, which offer robustness improvement of recognition against shooting angle.
