Based on the theory of wavelet matched filtering and the associative characteristic of volume holographic storage in a photorefractive crystal,a new idea for associative memory is proposed and realized.It can remember and recover a primary image from its deformed features.The photorefractive crystal in the system stands for both the cell of pattern identification and that of image restoring.Its application in face memory is studied,and experimental results are given
