چکیده

In the paper, fuzzy fisherface is extended to image matrix, namely, the fuzzy 2DLDA (F2DLDA). In the proposed method, we calculate the membership degree matrix by fuzzy K-nearest neighbor (FKNN), and then incorporate the membership degree into the definition of the between-class scatter matrix and the within-class scatter matrix. Finally, we get the fuzzy between-class scatter matrix and fuzzy within-class scatter matrix. In our definition of the between-class scatter matrix and within-class matrix, the fuzzy information is better used than fuzzy fisherface. Experiments on the Yale, ORL and FERET face databases show that the new method works well. & 2010 Elsevier B.V. All rights reserved.

A Comparative Study on Vector-based and Matrix-based Linear Discriminant Analysis

Recently a kind of matrix-based discriminant feature extraction approach called 2DLDA have been drawn much attention by researchers. 2DLDA can avoid the singularity problem and has low computational costs and has been experimentally reported that 2DLDA outperforms traditional LDA. In this paper, we compare 2DLDA with LDA in view of the discriminant power and find that 2DLDA as a kind of special...

New Feature Extraction Approaches for Face Recognition

All the traditional PCA-based and LDA-based methods are based on the analysis of vectors. So, it is difficult to evaluate the covariance matrices in such a high-dimensional vector space. Recently, two-dimensional PCA (2DPCA) and two-dimensional LDA (2DLDA) have been proposed in which image covariance matrices can be constructed directly using original image matrices. In contrast to the covarian...

An Integrated Face Recognition Algorithm Based on Wavelet Subspace

In this paper, based on the study of the Two-Dimensional Principal Component Analysis (2DPCA), Two-Dimensional Principal Component Analysis (2DPCA) and fuzzy set theory, we propose a integrated face recognition algorithm based on wavelet subspace. This method can make good use of the advantages of each single method, and also can make up for the defect of each other. The comparison of the resul...

Two-Dimensional Linear Discriminant Analysis

Linear Discriminant Analysis (LDA) is a well-known scheme for feature extraction and dimension reduction. It has been used widely in many applications involving high-dimensional data, such as face recognition and image retrieval. An intrinsic limitation of classical LDA is the so-called singularity problem, that is, it fails when all scatter matrices are singular. A well-known approach to deal ...

Feature Extraction based on Sub-Pattern Multi-Directional 2DLDA

A novel feature extraction method based on sub-pattern Multi-directional two-dimensional linear discriminate analysis (Sp-MD2DLDA) for face recognition is presented in this paper. In the proposed method, firstly, we apply directional 2DLDA (D2DLDA) to extract features in some initial directions, and then choose the effective directions from the initial directions for feature fusion after an eva...
