摘　　要：A study has been made on the solving method of optimal set of uncorrelated discriminant vectors in this pa-per. A new concise formula for solving the optimal set of uncorrelated discriminant vectors has been proposed. Thegeneralized discriminant KL transform is proposed based on the new formula, which is applied in the feature extrac-tion of facial images. The numerical experiments on facial database of ORL show the effectiveness of the proposedmethod.A study has been made on the solving method of optimal set of uncorrelated discriminant vectors in this paper.
