Robust Regression for Face Recognition<br />

Bennamoun, Mohammed, The Univ. of Western Australia<br />
In this paper we address the problem of illumination invariant face recognition. Using a fundamental concept that in<br />
general, patterns from a single object class lie on a linear subspace [2], we develop a linear model representing a probe<br />
image as a linear combination of class-specific galleries. In the presence of noise, the well-conditioned inverse problem<br />
is solved using the robust Huber estimation and the decision is ruled in favor of the class with the minimum reconstruction<br />
error. The proposed Robust Linear Regression Classification (RLRC) algorithm is extensively evaluated for two standard<br />
databases and has shown good performance index compared to the state-of-art robust approaches.<br />

Blur is often present in real-world images and significantly affects the performance of face recognition systems. To improve<br />
the recognition of blurred faces, we propose a new approach which inherits the advantages of two recent methods. The<br />
idea consists of first reducing the amount of blur in the images via deblurring and then extracting blur-tolerant descriptors<br />
for recognition. We assess our analysis on real blurred face images (FRGC 1.0 database) and also on face images artificially<br />
degraded by focus blur (FERET database), demonstrating significant performance enhancement compared to the state-ofthe-art.<br />

Diffusion-Based Face Selective Smoothing in DCT Domain to Illumination Invariant Face Recognition<br />
Ezoji, Mehdi, Amirkabir Univ. of Tech.<br />
Faez, Karim, Amirkabir Univ. of Tech.<br />
In this paper, a diffusion-based iterative algorithm is proposed for illumination invariant face representation using image<br />
selective smoothing in DCT domain. In fact, we split the image I into three parts (R+w)+L of an illumination invariant<br />
component, an oscillating component and a smooth component. At each iteration, the influence of different frequency<br />
sub-bands of image is determined and the additive oscillating component is reduced. The experimental results confirmed<br />
that our approach provides a suitable representation for overcoming illumination variations.<br />

BioHashing for Securing Fingerprint Minutiae Templates<br />
Belguechi, Rima, National School of Computer Science<br />
Rosenberger, Christophe, Lab. GREYC<br />
Ait Aoudia, Samy, National School of Computer Science<br />
The storage of fingerprints is an important issue as this biometric modality is more and more deployed for real applications.<br />
The a prori impossibility to revoke a biometric template (like a password) in case of theft, is a major concern for privacy<br />
reasons. We propose in this paper a new method to secure fingerprint minutiae templates by storing a bio code while keeping<br />
good recognition results. We show the efficiency of the method in comparison to some published methods for different<br />
scenarios.<br />
