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...

Learning with Multiple Orientations and Scales for Face Recognition
A novel feature fusion algorithm using multiple orientations and scales for illumination-robust face recognition is proposed in this paper. For a given image, it will firstly be transformed by a group of Gabor...

A Multi-scale Dynamically Growing Hierarchical Self-organizing Map for Brain MRI Image Segmentation
With Kohonen’s self-organizing map based brain MRI image segmentation, there are still some regions which are not partitioned accurately, particularly in the transitional regions of gray matter and white matte...

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...
