Introducing Geometry in Active Learning for Image Segmentation

Pascal Fua, Raphael Sznitman, Ksenia Konyushkova

We propose an Active Learning approach to training a segmentation classifier that exploits geometric priors to streamline the annotation process in 3D image volumes. To this end, we use these priors not only to select voxels most in need of annotation but ...

Scale Model Evaluation and Optimization of Sodar Acoustic Baffles

Fernando Porté Agel, Adrien Chabbey

A 21: 1 scaled sodar, operating at 40 kHz, has been built and tested in the laboratory. Sodars, which use sound scattered by turbulence to profile the lowest few hundred meters of the atmosphere, need good acoustic shielding to diminish annoyance and to re ...

Superconducting scanning tunneling microscopy tips in a magnetic field: Geometry-controlled order of the phase transition

Klaus Kern, Markus Etzkorn, Matthias Alexander Eltschka, Maximilian Assig

The properties of geometrically confined superconductors significantly differ from their bulk counterparts. Here, we demonstrate the geometrical impact for superconducting scanning tunneling microscopy (STM) tips, where the confinement ranges from the atom ...

The role of elastic waves during dynamic rupture of heterogeneous interfaces

Jean-François Molinari, Fabian Barras

Along a planar interface bonding two solids made of Homalite, we simulate rupture events in the presence of a unique tougher inclusion with insights on the influence of its geometry and fracture properties. Our study is then pursued with fracture planes ma ...

MATHICSE Technical Report : FaCSI : A block parallel preconditioner for fluid-structure interaction in hemodynamics

Alfio Quarteroni, Simone Deparis, Davide Forti, Gwenol Grandperrin

Modeling Fluid-Structure Interaction (FSI) in the vascular system is mandatory to reliably compute mechanical indicators in vessels undergoing large deformations. In order to cope with the computational complexity of the coupled 3D FSI problem after discre ...

Curve Graphs On Surfaces Of Infinite Type

Hugo Parlier, Ariadna Fossas Tenas

We define and study analogs of curve graphs for infinite type surfaces. Our definitions use the geometry of a fixed surface and vertices of our graphs are infinite multicurves which are bounded in both a geometric and a topological sense. We show that the ...

Graph-based representation for multiview image geometry

Pascal Frossard, Thomas Maugey

In this paper, we propose a new representation for multiview image sets. Our approach relies on graphs to describe geometry information in a compact and controllable way. The links of the graph connect pixels in different images and describe the proximity ...

Seam Carving for Text Line Extraction on Color and Grayscale Historical Manuscripts

Sabine Süsstrunk, Nikolaos Arvanitopoulos Darginis

We propose a novel algorithm for automatic text line extraction on color and grayscale manuscript pages without prior binarization. Our algorithm is based on seam carving to compute separating seams between text lines. Seam carving is likely to produce ...

Nonlinear Plasmonic Nanorulers

Olivier Martin, Jérémy Butet

The evaluation of distances as small as few nanometers using optical waves Is a very challenging task that can pave the way for the development of new applications in biotechnology and nanotechnology. In this article, we propose a new measurement method ba ...

Probing the size of proteins with glass nanopores

Aleksandra Radenovic, Melanie Blokesch, Lely Feletti, Lorenz Jan Steinbock, Roman Bulushev, Swati Krishnan

Single molecule studies using nanopores have gained attention due to the ability to sense single molecules in aqueous solution without the need to label them. In this study, short DNA molecules and proteins were detected with glass nanopores, whose sensiti ...
