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. ...

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 ...

Physical modelling to better understand rock avalanches

Vincent Labiouse, Irene Manzella

Several authors have resorted to physical modelling in the field of rock avalanches. After a review of some of these works, the present paper describes tests carried out at the Ecole Polytechnique Fédérale de Lausanne. The main goal of these experiments, i ...

View-Based Maps

Pascal Fua, Vincent Lepetit, Michael Calonder

Robotic systems that can create and use visual maps in real-time have obvious advantages in many applications, from automatic driving to mobile manipulation in the home. In this paper we describe a mapping system based on retaining stereo views of the envi ...

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 ...

Phase extraction in dynamic speckle interferometry: proposal of a road map

Sébastien Equis

Of all the two-beam interference patterns, the ones obtained in speckle interferometry (SI) are the most difficult to be phase-demodulated. Many solutions exist in classical smooth-wave interferometry and alike techniques, both in static and dynamic regime ...

Spectral analysis and experimental study of lateral capillary dynamics for flip-chip applications

Massimo Mastrangeli

This article presents a study on the dynamics of lateral motion of a liquid meniscus confined by a pad and a chip moving parallel to the pad. This problem is a typical flip-chip case study, whose use is widespread in industrial assembly. The proposed model ...

Micrometeorological and morphological observations of surface hoar dynamics on a mountain snow cover

Michael Lehning, Charles Fierz

The formation, growth, and destruction of surface hoar crystals is an important feature of mountain snow covers as buried surface hoar layers are a frequent weak layer leading to unstable snowpacks. The energy and mass exchange associated with surface hoar ...

Communication-based Swarming for Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

We aim at implementing a swarm of Micro-Air-Vehicles for creating communication networks (SMAVNETs) in disaster areas. For this purpose, we propose strategies for steering flying robots using only communication hardware (e.g. WiFi module or radio modem) an ...

Reducing distortions in diffusion-weighted echo planar imaging with a dual-echo blip-reversed sequence

Daniel Gallichan

The inherent distortions in echo-planar imaging that arise due to inhomogeneities in the static magnetic field can lead to difficulties when attempting to obtain structurally accurate diffusion-tensor imaging data. Parallel acceleration techniques can redu ...
