摘要
构建了基于体全息存储技术的光学图像识别系统 ,应用在以实时人脸识别为基础的 电子门卫 系统中 .改变了传统的体全息存储相关器中以相关峰值强度作为判别依据的做法 ,采用基于多元鉴别分析的分类识别 ,增强了系统的畸变不变性识别能力 .
An optical image recognition system based on the volume holographic storage technology is constructed. It is applied to an “electronic guard” system based on the real time human face recognition. It changes the conventional discriminating rule according to the intensities of the correlation peaks in volume holographic storage correlator, and uses the multivariate discriminant analysis based classification method so that the distortion invariance recognition ability is improved.
