Face Recognition under Variable Illumination by Weighted-Subband Edge Enhancement
This article presents a novel weighted-subband method based on wavelet decomposition for face recognition under variable illumination. Different levels of subbands contain different features of the edge of a h...

Face Recognition by Inverse Fisher Discriminant Features
For face recognition task the PCA plus LDA technique is a famous two-phrase framework to deal with high dimensional space and singular cases. In this paper, we examine the theory of this framework: (1) LDA can...

Wavelet-Based 2-Parameter Regularized Discriminant Analysis for Face Recognition
This paper addresses the small-size problem in Fisher Discriminant Analysis. We propose to use wavelet transform for preliminary dimensionality reduction and use a two-parameter regularization scheme for the w...

Face Recognition Based on Local Fisher Features
To efficiently solve human face image recognition problem with an image database, many techniques have been proposed. A key step in these techniques is the extraction of features for indexing in the database a...
