Consistent view synthesis in interactive multiview imaging

An important question in the design of interactive multiview systems consists in determining the information needed by the decoder for high quality navigation between the views. Most of the existing techniques focus on the captured sequences and only consi ...

Modélisation physique et analyse numérique de la propagation d'une masse granulaire

Claire Sauthier

Rock avalanches are processes involving a huge amount of mobilised material, larger than 106 m3, and their propagation is characterised by a very high energy, such that no active mitigation measure is capable of protecting human lives and properties potent ...

Retrieval of occluded images using DCT phase and region merging

Pierre-André Farine, Sara Grassi Pauletti, Pradyumna Ayyalasomayajula

In this paper we present an efficient method for Content Based Image Retrieval (CBIR) of occluded images using DCT-phase. The proposed method utilizes a novel correlation metric for ternary-valued DCT-phase, as well as a region merging method to reconstruc ...

Quantification of the Small-Scale Spatial Structure of the Raindrop Size Distribution from a Network of Disdrometers

Alexis Berne, Joël Jaffrain

The spatial structure of the raindrop size distribution (DSD) conveys crucial information for reliable quantitative estimation of rainfall using remote sensing techniques. To investigate this question, a network of 16 optical disdrometers has been deployed ...

Impact of climate change on runoff pollution in urban environments

David Andrew Barry, Sylvain Coutu, Sébastien Kramer

Runoff from urban environments is generally contaminated. These contaminants mostly originate from road traffic and building envelopes. Facade envelopes generate lead, zinc and even biocides, which are used for facade protection. Road traffic produces part ...

Spatial modelling of extreme snow depth

Anthony Christopher Davison, Juliette Ferial Blanchet

The spatial modelling of extreme snow is important for adequate risk management in Alpine and high altitude countries. A natural approach to such modelling is through the theory of max-stable processes, an infinite-dimensional extension of multivariate ext ...

Spatio-temporal measurements and analysis of snow depth in a rock face

Michael Lehning

Snow in rock faces plays a key role in the alpine environment for permafrost distribution, snow water storage or runoff in spring. However, a detailed assessment of snow depths in steep rock walls has never been attempted. To understand snow distribution i ...

A network of disdrometers to quantify the small-scale variability of the raindrop size distribution

Alexis Berne, André Studzinski, Joël Jaffrain

Insight into the spatial variability of the (rain) drop size distribution (DSD), and hence rainfall, is of primary importance for various environmental applications like cloud/precipitation microphysical processes, numerical weather modeling, and estimatio ...

Hyporheic flow under periodic bed forms influenced by low-density gradients

David Andrew Barry

Small density variations due to low solute concentrations in the stream water commonly exist in streams and rivers. Using laboratory experiments and numerical modeling, we demonstrated that even such small density variations could influence the hyporheic f ...

Self-entrainment of air on stepped spillways

Michael Pfister

The pseudo-bottom-inception point related to air entrainment is located further upstream on stepped spillways than on smooth spillways, for otherwise identical conditions. Its position is relevant concerning cavitation aspects, flow losses and flow depths. ...
