摘要
基于子波匹配相关理论和光折变晶体的体全息关联存储特性 ,提出并实现了一个关联记忆的新构思。该系统可根据缺损特征实现原始图像的记忆和恢复 ,其中光折变晶体兼作图像识别时的运算单元和图像恢复时的存储单元。文中以人脸为研究对象 。
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. Itcan remember and recover a primary image from its deformed fea- tures. The photorefractive crystal in the system stands for both the cell of pattern identifica- tion and that of image restoring.Its application in face memory is studied,and experimental results are given.
