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...

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...

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...

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...
