Effect of collisions on non-adiabatic electron dynamics in ITG-driven microturbulence
Stephan Brunner, Justin Richard Ball
Non-adiabatic electron response leads to significant changes in ion temperature gradient (ITG) eigenmodes, leading, in particular, to fine-structures that are significantly extended along the magnetic field lines at corresponding mode rational surfaces (MR ...
AIP Publishing2021Tracing in 2D to reduce the annotation effort for 3D deep delineation of linear structures
Pascal Fua, Mathieu Salzmann, Agata Justyna Mosinska, Mateusz Kozinski
The difficulty of obtaining annotations to build training databases still slows down the adoption of recent deep learning approaches for biomedical image analysis. In this paper, we show that we can train a Deep Net to perform 3D volumetric delineation giv ...
ELSEVIER2020Effect of pool confinement on pressures around a block impacted by plunging aerated jets
Anton Schleiss, Rafael Xavier Meriade Duarte
The erosion caused by jets issued from hydraulic structures progressively develops a confined scour-hole on the riverbed. A realistic scour assessment must consider both the influence of the air entrained when the jet plunges into the pool and the flow pat ...
National Research Council Canada2016Graph-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 ...
Institute of Electrical and Electronics Engineers2015Robust Image Reconstruction from Multiview Measurements
Pierre Vandergheynst, Gilles Puy
We propose a novel method to accurately reconstruct a set of images representing a single scene from a few linear multiview measurements. Each observed image is modeled as the sum of a background image and a foreground one. The background image is common t ...
Siam Publications2014Studying edge geometry in transiently turbulent shear flows
In linearly stable shear flows at moderate Reynolds number, turbulence spontaneously decays despite the existence of a codimension-one manifold, termed the edge, which separates decaying perturbations from those triggering turbulence. We statistically anal ...
Cambridge University Press2014Graph-based representation and coding of multiview geometry
Pascal Frossard, Thomas Maugey
We propose a new approach for describing the geometry information of multiview image representations. Rather than transmitting the raw geometry of the scene, under the form of depth information, we build a graph that represents the connections between corr ...
2013Compressed Sensing of Multiview Images Using Disparity Compensation
Compressed sensing is applied to multiview image sets and inter- image disparity compensation is incorporated into image recon- struction in order to take advantage of the high degree of inter- image correlation common to multiview scenarios. Instead of re ...
