Fast Bias Field Correction for 9.4 Tesla Magnetic Resonance Imaging

Jean-Philippe Thiran, Rolf Gruetter, Meritxell Bach Cuadra, Nicolas Kunz, Nathalie Just, Xavier Pena Pina

In this paper the problem of intensity inhomogeneity at high magnetic field on magnetic resonance images is addressed. Specifically, rat brain images at 9.4T acquired with a surface coil are bias corrected. We propose a low- pass frequency model that takes ...

Shape from Texture for Omnidirectional Images

Pierre Vandergheynst, Luigi Bagnato, Laurent Jacques, Eugenio De Vito

In this paper, we describe a method to infer 3-D scene information using a single view captured by an omnidirectional camera. The proposed technique is inscribed in the so called ``Shape from Texture'' problem : if the textures hold by 3-D surfaces respect ...

UWB and MEMS Based Indoor Navigation

Bertrand Merminod, Sylvain Pittet

Thanks to its physical characteristics, Ultra-wideband (UWB) is one of the most promising technologies for indoor pedestrian navigation. UWB radio localisation systems however experience multipath phenomena that decrease the precision and the reliability o ...

Distributed signal processing for binaural hearing aids

Olivier Roy

Over the last centuries, hearing aids have evolved from crude and bulky horn-shaped instruments to lightweight and almost invisible digital signal processing devices. While most of the research has focused on the design of monaural apparatus, the use of a ...

Noise analysis in super-regenerative receiver systems

Catherine Dehollain, Michel Declercq

The recent increase in the need for energy efficient wireless nodes have led to the study of various low power consumption receiver and transmitter architectures. The super-regenerative receiver architecture is one of the possible candidates for such a low ...

Phenomenological models of synaptic plasticity based on spike timing

Wulfram Gerstner

Synaptic plasticity is considered to be the biological substrate of learning and memory. In this document we review phenomenological models of short-term and long-term synaptic plasticity, in particular spike-timing dependent plasticity (STDP). The aim of ...

Particle filter-based camera tracker fusing marker- and feature point-based cues

Touradj Ebrahimi, Yousri Abdeljaoued

This paper presents a video-based camera tracker that combines marker-based and feature point-based cues in a particle filter framework. The framework relies on their complementary performances. Marker-based trackers can robustly recover camera position an ...

Modeling the Isoelectric Focusing of Peptides in an OFFGEL Multicompartment Cell

Hubert Girault, Niels Erik Lion, Hoang-Trang Lam

In proteomic analysis of complex samples at the peptide level (termed shotgun proteomics), an effective prefractionation is crucial to decrease the complexity of the peptide mixture for further analysis. In this perspective, the high-resolving power of the ...
