Pupil Lovalization And Tracking For Video-Based Iris Biometrics
Nedra Benletaief, Amel Benazza-Benyahia, Stephane Derrode
In this paper, we are interested in iris biometric applications. More precisely, our contribution consists in designing both a pupil detection and a tracking procedure from video s…
A Hierarchical Bayesian Model for Frame Representation
L. Chaâri, J. -C. Pesquet, J. -Y. Tourneret +2
In many signal processing problems, it may be fruitful to represent the signal under study in a frame. If a probabilistic approach is adopted, it becomes then necessary to estimate…
An Iterative Method for Parallel MRI SENSE-based Reconstruction in the Wavelet Domain
Lotfi Chaari, Jean-Christophe Pesquet, Philippe Ciuciu +1
To reduce scanning time and/or improve spatial/temporal resolution in some MRI applications, parallel MRI (pMRI) acquisition techniques with multiple coils acquisition have emerged…
A SURE Approach for Digital Signal/Image Deconvolution Problems
Jean-Christophe Pesquet, Amel Benazza-Benyahia, Caroline Chaux
In this paper, we are interested in the classical problem of restoring data degraded by a convolution and the addition of a white Gaussian noise. The originality of the proposed ap…
A nonlinear Stein based estimator for multichannel image denoising
Caroline Chaux, Laurent Duval, Amel Benazza-Benyahia +1
The use of multicomponent images has become widespread with the improvement of multisensor systems having increased spatial and spectral resolutions. However, the observed images a…
