Variational B-Spline Level-Set Method for Fast Image Segmentation
Michaël Unser, Philippe Thévenaz
In the field of image segmentation, most of level-set-based active contour approaches are based on a discrete representation of the associated implicit function. We present in this paper a different formulation where the level-set is modelled as a continuo ...
IEEE2008Adaptive Beamforming with a Maximum Negentropy Criterion
Philip Neil Garner, Weifeng Li
In this paper, we address an adaptive beamforming application in realistic acoustic conditions. After the position of a speaker is estimated by a speaker tracking system, we construct a subband-domain beamformer in generalized sidelobe canceller (GSC) conf ...
2008Fast Multiview Face Tracking with Pose Estimation
Jean-Philippe Thiran, Javier Cruz Mota, Julien Meynet
In this paper, a fast and effective multi-view face tracking algorithm with head pose estimation is introduced. For modeling the face pose we employ a tree of boosted classifiers built using either Haar-like filters or Gauss filters. A first classifier ext ...
2007Minimum Mutual Information Beamforming for Simultaneous Active Speakers
In this work, we consider an acoustic beamforming application where two speakers are simultaneously active. We construct one subband-domain beamformer in \emph{generalized sidelobe canceller} (GSC) configuration for each source. In contrast to normal pract ...

IDIAP2007Multi-system biometric authentication
Verifying a person's identity claim by combining multiple biometric systems (fusion) is a promising solution to identity theft and automatic access control. This thesis contributes to the state-of-the-art of multimodal biometric fusion by improving the und ...
EPFL2007Computation over Multiple-access Channels
The problem of reliably reconstructing a function of sources over a multiple-access channel (MAC) is considered. It is shown that there is no source-channel separation theorem even when the individual sources are independent. Joint source-channel strategie ...
