DAISY: A Fast Descriptor for Dense Wide Baseline Stereo and Multiview Reconstruction

Stereo reconstruction is a fundamental problem of computer vision. It has been studied for more than three decades and significant progress has been made in recent years as evidenced by the quality of the models now being produced. This is highly related w ...

In vitro and in vivo photocytotoxicity of boron dipyrromethene derivatives for photodynamic therapy

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Siang Hui Lim

To understand the effects of substitution patterns on photosensitizing the ability of boron dipyrromethene (BODIPY), two structural variations that either investigate the effectiveness of various iodinated derivatives to maximize the "heavy atom effect" or ...

Daisy: An Efficient Dense Descriptor Applied to Wide Baseline Stereo

Pascal Fua, Vincent Lepetit, Engin Tola

In this paper, we introduce a local image descriptor, DAISY, which is very efficient to compute densely. We also present an EM based algorithm to compute dense depth and occlusion maps from wide baseline image pairs using this descriptor. This yields much ...

Flow experiments with gravel and blocks at small scale to investigate parameters and mechanisms involved in rock avalanches

Vincent Labiouse, Irene Manzella

Laboratory experiments play an important role in improving the modelling of rock avalanches since they contribute to a better understanding of the mechanisms that characterise propagation and to identifying parameters influencing velocity and deposit chara ...

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

Alexis Berne, André Studzinski, Joël Jaffrain, Florian Pantillon

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 ...

Pore scale analyses of evaporation from porous media

Nima Shokri

Evaporation from porous media is a key process in the hydrologic cycles, waste isolation, biological and food processes and other engineering application. Drying rate and patterns in porous media are strongly influenced by transport properties of the mediu ...

Drying front and water content dynamics during evaporation from sand delineated by neutron radiography

Dani Or, Nima Shokri

Evaporative drying of porous media is jointly controlled by external ( atmospheric) conditions and by media internal transport properties. Effects of different atmospheric potential evaporative demand on observed drying rates were studied in a series of la ...

An intuitive daylighting performance analysis and optimization approach

Marilyne Andersen, Magali Bodart

The effective integration of daylighting considerations into the design process requires many issues to be considered simultaneously, such as daily and seasonal variations, illumination, and thermal comfort. To address the need for early integration into t ...

Dry rock avalanche propagation

Irene Manzella

Rock avalanches are catastrophic phenomena which are not yet exhaustively understood. They consist of rock mass movements of more than one million cubic metres, involving a great amount of energy and travelling farther than expected with a normal sliding f ...
