摘　　要：定义了特征识别向量并提出了图像识别模板的概念 ,在此基础上发展了相关系数的算法 ,对存有 10 0幅图像的体全息图像库所进行的模式识别实验表明此算法能够有效地提高识别准确率。The characteristic recognition vector and the template matrix are proposed for image recognition based on volume holographic storage image-databases, which include the effect of the non-uniform diffraction efficiency upon the recognition accuracy. With such vectors and the matrices, the comparison study has been performed experimentally about several recognition algorithms, and it is found that the scheme of correlation coefficient is optimum.
