Feature Harvesting for Tracking-by-Detection

Pascal Fua, François Fleuret, Vincent Lepetit, Mustafa Özuysal

We propose a fast approach to 3D object detection and pose estimation that owes its robustness to a training phase during which the target object slowly moves with respect to the camera. No additional information is provided to the system, save a very roug ...

Assessment of insulated conductive cantilevers for biology and electrochemistry

Nico de Rooij, Terunobu Akiyama

This paper describes the characterization and application of electrically insulated conductive tips mounted on a cantilever for use in an atomic force microscope and operated in liquid. These multifunctional probes were microfabricated and designed for mea ...

A Variational Model for Object Segmentation Using Boundary Information, Statistical Shape Prior and the Mumford-Shah Functional

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson

In this paper, we propose a variational model to segment an object belonging to a given scale space using the active contour method, a geometric shape prior and the Mumford-Shah functional. We define an energy functional composed by three complementary ter ...

A Variational Definition of Electrostatic Potential Derived Charges

Ursula Röthlisberger

In a recent work [Laio, A., VandeVondele, J., Rothlisberger, U. J. Phys. Chem. B 2002 106, 7300] a novel method has been proposed to define dynamical electrostatic potential derived (D-RESP) charges for systems described within a quantum mechanics/mol. mec ...

Multiscale Variational Approach to Simultaneous Image Regularization and Segmentation

Pierre Vandergheynst

The problem of finding a piecewise smooth approximation of an original image while preserving edges is closely related to the image segmentation problem. Indeed, if we know the cartoon version of the original image, it is easier to perform an image partiti ...

An Exact Relation Between Willingness To Pay and Willingness To Accept

Thomas Alois Weber

I present a simple and precise relationship between the willingness-to-pay and the willingness-to-accept, or equivalently between the compensating and equivalent variations following an exogenous welfare change. One can be computed given the other as a fun ...

Video Shot Clustering using Spectral Methods

Daniel Gatica-Perez, Jean-Marc Odobez

The automatic segmentation and structuring of videos present technical challenges due to the large variation of content, spatial layout, and possible lack of storyline. In this paper, we propose a spectral method to group video shots into scenes based on t ...

One-dimensional biexcitons in a single quantum wire

Benoît Marie Joseph Deveaud, Andrea Crottini, Xiao Wang

We report the direct observation of one-dimensional (ID) excitonic molecules (biexcitons) in high quality disorder free semiconductor quantum wires. By means of spatially resolved near-field photoluminescence spectroscopy, we detected delocalized 1D excito ...

Genomics of Mycobacterium bovis

Stewart Cole

The imminent completion of the genome sequence of Mycobacterium bovis will reveal the genetic blueprint for this most successful pathogen. Comparative analysis with the genome sequences of M. tuberculosis and M. bovis BCG promises to expose the genetic bas ...

A model for the consolidation of warp-knitted reinforced laminates

Véronique Michaud, Pierre-Etienne Bourban

A model for the consolidation of thermoplastic composites reinforced with a warpknitted fabric was developed. The evolution of void content during composite consolidation achieved via film stacking was related to the processing parameters and the material ...
