An optimal first-order solver for the TV-$L_1$ optical flow problem

Pierre Vandergheynst, Gilles Puy, Emmanuel D'Angelo

In this study, we address the problem of computing efficiently a dense optical flow between two images under a total variation (TV) regularization and an

L_1

norm data fidelity constraint using a variational method. We build upon Nesterov's framework for ...

Ultraviolet and near-infrared femtosecond temporal pulse shaping with a new high-aspect-ratio one-dimensional micromirror array

Nico de Rooij, Wilfried Noell, Jean-Pierre Wolf, Jérôme Extermann, Luigi Bonacina

We demonstrate the capabilities of a new optical microelectromechanical systems device that we specifically developed for broadband femtosecond pulse shaping. It consists of a one-dimensional array of 100 independently addressable, high-aspect-ratio microm ...

Electromechanics on the Nanometer Scale: Emerging Phenomena, Devices, and Applications

Nava Setter

Coupling between electrical and mechanical phenomena is ubiquitous in nature and underpins the functionality of materials and systems as diversified as ferroelectrics and multiferroics to electroactive molecules to biological systems. Recent years have wit ...

Molecular Ionic Junction for Enhanced Electronic Charge Transfer

Mohammad Khaja Nazeeruddin, Diego Repetto

We present the first evidence of charge injection improvement in an organic electroluminescent device provided by a single ionic molecular layer. A hole-dominated, hybrid organic-inorganic light-emitting device is used as a probe to verify the effectivenes ...

A comb drive actuated vertically moving micromirror for tunable mid-infrared Resonant Cavity Enhanced Detectors

Niels Quack

The realization of a vertically moving micromirror using electrostatic actuation in a comb drive configuration is presented. The micromirror is designed for the use in tunable mid-infrared Resonant Cavity Enhanced Detectors (RCEDs). It can be displaced mor ...

Physical-virtual linkage with contextual bookmarks

Xavier Righetti

In our everyday life we often see objects or persons and are aware that there are related digital services such as an online ticket service when seeing a poster advertising a concert. Currently it is a rather time consuming activity to find the related inf ...

An Analytical Model to Evaluate the Radiated Power Spectrum of a Multipactor Discharge in a Parallel-Plate Region

Francisco Edén Sorolla Rosario, Alejandro Alvarez

This paper is aimed at studying the electromagnetic radiation pattern of a multipactor discharge occurring in a parallel-plate waveguide. The proposed method is based on the Fourier expansion of the multipactor current in terms of time-harmonic currents ra ...

Tracking the free surface of time-dependent flows: Image processing for the dam-break problem

Christophe Ancey, Steve Cochard

The dam-break problem (i.e., the sudden release of a given volume of fluid down a slope) has attracted a great deal of attention from mechanicians and physicists over the past few years, with particular interest devoted to the free-surface profile and the ...

A comparative study of JPEG 2000, AVC/H.264, and HD Photo

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux, Mourad Ouaret

In this paper, we report a study evaluating rate-distortion performance between JPEG 2000, AVC/H.264 High 4:4:4 Intra and HD Photo. A set of ten high definition color images with different spatial resolutions has been used. Both the PSNR and the perceptual ...

Parallel broadband fluorescent light source for optical coherence tomography

René Salathé, Theo Lasser, Stéphane Bourquin

We present a new light source for parallel Optical Coherence Tomography (OCT) based on multiple waveguides written in Ti:sapphire. Each channel can generate a spectrum of 174 nm bandwidth centered at 772 nm, with an optical power on sample of 30 mu W. A sy ...
