The Generalized DKL Transform and it''''s Application on Face Image Recognition
广义DKL变换及其在人脸识别中的应用研究

A study has been made on the solving method of optimal set of uncorrelated discriminant vectors in this paper. A new concise formula for solving the optimal set of uncorrelated discriminant vectors has been proposed. The generalized discriminant KL transform is proposed based on the new formula, which is applied in the feature extraction of facial images. The numerical experiments on facial database of ORL show the effectiveness of the proposed method.
