An Improved D-LDA Based Face Recognition Using the Entire Information of Within-Class Scatter Matrix
Direct linear discriminant analysis (DLDA) based methods have been successfully and widely used in face recognition, yet little work has been focused on the remaining subspace of within-class scatter matrix, in which exists more useful information for discrimination. In this paper we first present the traditional D-LDA based face recognition algorithm, and then calculate the remaining subspace by eliminating the spanning subspace of existing projecting vectors based on traditional D-LDA from subspace of Sw. Subsequently, adjusting factor is proposed, which is used to adjust the distances or projecting coordinates. The experimental results show that the modified D-LDA improves the recognition accuracy of a face recognition system.
