6. MEMS based color-VGA micro-projector system

Maher Kayal, Laurent Fabre, Fabrizio Lo Conte, Nicolas Abelé, Thierry Barras, Didier Raboud

This paper presents a complete portable laser-based projection system using twofold of one dimensional magnetic actuated MEMS linear scanning micro-mirrors. Dedicated high speed electronics was developed to drive the MEMS, detect the mirror scanning positi ...

Wavelet transform on manifolds: old and new approaches

Pierre Vandergheynst

Given a two-dimensional smooth manifold M and a bijective pro jection p from M on a ﬁxed plane (or a subset of that plane), we explore systematically how a wavelet transform (WT) on M may be generated from a plane WT by the inverse projection. Examples whe ...

A Closed-Form Solution for the Uniform Sampling of the Epipolar Line via Non-Uniform Depth Sampling

Engin Tola

Given two camera calibrations, this report presents a closed form algorithm that computes a sequence of 3D points such that they all project to a single location on one camera and that their projection forms a uniformly sampled line on the other camera. ...

Exploring Ambiguities for Monocular Non-Rigid Shape Estimation

Pascal Fua

Recovering the 3D shape of deformable surfaces from single images is difficult because many different shapes have very similar projections. This is commonly addressed by restricting the set of possible shapes to linear combinations of deformation modes and ...

Integrating geo-referenced multiscale and multidisciplinary data for the management of biodiversity in livestock genetic resources

Stéphane Joost

In livestock genetic resource conservation, decision making about conservation priorities is based on the simultaneous analysis of several different criteria that may contribute to long-term sustainable breeding conditions, such as genetic and demographic ...

Distributed Sensor Perception via Sparse Representation

Michael Christoph Gastpar

In this paper, sensor network scenarios are considered where the underlying signals of interest exhibit a degree of sparsity, which means that in an appropriate basis, they can be expressed in terms of a small number of nonzero coefficients. Following the ...

On Random Tomography with Unobservable Projection Angles

Victor Panaretos

We formulate and investigate a statistical inverse problem of a random tomographic nature, where a probability density function on

\mathbb{R}^3

is to be recovered from observation of finitely many of its two-dimensional projections in random and unobserv ...

Micro-beamer based on MEMS micro-mirrors and laser light source

Maher Kayal, Laurent Fabre, Fabrizio Lo Conte, Nicolas Abelé, Christophe Winter

This paper presents a complete portable laser-based projection system using two one-dimensional magnetic actuated MEMS linear scanning micro-mirrors. Dedicated high speed electronics was developed to drive the MEMS, detect the mirror scanning position at a ...

Experimental investigation into localized instabilities of mixed Rayleigh-Benard-Poiseuille convection

Peter Monkewitz, Emeric Grandjean

The stability of the Rayleigh-Benard-Poiseuille flow in a channel with large transverse aspect ratio (ratio of width to vertical channel height) is studied experimentally. The onset of thermal convection in the form of 'transverse rolls' (rolls with axes p ...

A compressive beamforming method

Volkan Cevher

Compressive Sensing (CS) is an emerging area which uses a relatively small number of non-traditional samples in the form of randomized projections to reconstruct sparse or compressible signals. This paper considers the direction-of-arrival (DOA) estimation ...
