Compressed Sensing and Bayesian Experimental Design

We relate compressed sensing (CS) with Bayesian experimental design and provide a novel efficient approximate method for the latter, based on expectation propagation. In a large comparative study about linearly measuring natural images, we show that the si ...

Méthodologie pour l'analyse d'une répartition modale et spatiale plus durable du trafic

Raphaëlle Arnaud

There has been a significant growth in freight traffic over the last few decades in Europe. The Alps, located in the middle of North-South route, are particularly sensitive regarding this evolution because of their topographic and climatic characteristics. ...

How much confidence do we have in a MRI tractography experiment?

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Xavier Gigandet

When performing a tractography experiment it is essential to know whether a reconstructed tract results from the diffusion signal itself or from some random effect or noise. In this study, we introduce a way to associate to every connection a confidence le ...

Towards Automated LiDAR Boresight Self-calibration

Jan Skaloud

This paper focuses on practical aspects when performing boresight calibration in airborne laser scanning using rigorous methodology implemented in LIBOR software. LIBOR technique, introduced by (Skaloud and Lichti, 2006), is based on expressing the boresig ...

Hall sensor and method of operating a Hall sensor

Giovanni Boero, Radivoje Popovic, Pavel Kejik, Predrag Drljaca

A Hall sensor comprises a Hall element (1; 30; 31; 60) and an amplifier (2; 32; 33). The Hall element is placed inside the amplifier so that the current flowing through the Hall element also flows through the transistors of an amplifier stage of the amplif ...

A joint radar-acoustic particle filter tracker with acoustic propagation delay compensation

Volkan Cevher

In this paper, a novel particle filter tracker is presented for target tracking using collocated radar and acoustic sensors. Real-time tracking of the target's position and velocity in Cartesian coordinates is performed using batches of range and direction ...

Pattern Recognition from One Example by Chopping

François Fleuret

We investigate the learning of the appearance of an object from a single image of it. Instead of using a large number of pictures of an object to be recognized, we use pictures of other objects to learn invariance to noise and variations in pose and illumi ...

Compensation des non-linéarités des systèmes haut-parleurs à pavillon

Delphine Bard

The assumptions of linearity and autonomy assumed in circuit theory are known to be respected only partially by electroacoustic transducers. In particular, the dynamics range of the latter is limited by the audible nonlinear effects that they are causing. ...

Microphone Array Post-filter for Diffuse Noise Field

Hervé Bourlard

This paper proposes a novel technique for estimating the signal power spectral density to be used in the transfer function of a microphone array post-filter. The technique is a modification of the existing Zelinski post-filter, which uses the auto- and cro ...

Contribution à l'étude des modes de rayonnement acoustique d'une structure

Olivier Schevin

Noise radiated by different industrial structures that surround us in daily life are more and more considered as environmental pollution. Standards defining a tolerable sound level for each of these noise sources are regularly called into question and resp ...
