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.
