Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Tracking Multiple Players using a Single Camera

Pascal Fua, François Fleuret, Horesh Beny Ben Shitrit, Mirko Raca

It has been shown that multi-people tracking could be successfullly formulated as a Linear Program to process the output of multiple fixed and synchronized cameras with overlapping fields of view. In this paper, we extend this approach to the more challeng ...

Camera design for the simultaneous capture of near-infrared and visible images

Sabine Süsstrunk, Yue Lu

A camera for simultaneously capturing a visible and near-infrared (NIR) image of one or more objects, the camera comprising: at least one colour filter array (CFA) including at least four different filters, said at least one colour filter array having visi ...

FACT - The First G-APD Cherenkov Telescope (first results)

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

In October 2011, the first air-Cherenkov telescope utilizing Geiger-mode avalanche photodiodes commenced operations. The silicon-based devices display several advantages compared to classical photomultiplier tubes allowing for a more compact camera design ...

Drones to the Rescue!

Jan Skaloud

The use of unmanned aerial systems for civilian search-and-rescue operations or disaster management is not new. Predators drones, commonly associated with military operations, were used in the aftermath of the hurricane Katrina in the United States; rotary ...

Results of the prototype camera for FACT

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Atmospheric Cherenkov Telescopes. Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomulti ...

Field of view extension using satellite pinhole cameras

Hans Peter Herzig, Toralf Scharf

An approach to extend the field of view of a miniaturised imaging system is introduced. This innovative approach uses multiple optical systems working in parallel and image post-processing. As an example, a module consisting of a central single micro-lens ...

On Pixel Detection Threshold in the Gigavision Camera

Martin Vetterli, Edoardo Charbon, Sabine Süsstrunk, Luciano Sbaiz, Feng Yang

Recently, we have proposed a new image device called gigavision camera whose most important characteristic is that pixels have binary response. The response function of a gigavision sensor is non-linear and similar to a logarithmic function, which makes th ...

Automatic Skin Enhancement with Visible and Near-Infrared Image Fusion

Sabine Süsstrunk, Daniel Tamburrino

Skin tones, portraits in particular, are of critical importance in photography and video, but a number of factors, such as pigmentation irregularities (e.g., moles, freckles), irritation, roughness, or wrinkles can reduce their appeal. Moreover, such “defe ...

Using Digital Cameras as Quasi-Spectral Radiometers to Study Complex Fenestration Systems

Marilyne Andersen

This work discusses the use of digital cameras fitted with absorption filters as quasi-spectral radiometers. By filtering incident light into selected wavelength intervals, accurate estimates of radiances can be made for unknown spectra. This approach is b ...

Single-photon image sensors in CMOS

Cristiano Niclass

Among advanced electronic designs, vision systems are perhaps those that have undergone the most dramatic technological revolutions of the last decades. Recently, a new family of vision systems has emerged aimed at three-dimensional (3D) imaging. Many appl ...
