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.

Services surround you: Physical-virtual linkage with contextual bookmarks

Xavier Righetti

Our daily life is pervaded by digital information and devices, not least the common mobile phone. However, a seamless connection between our physical world, such as a movie trailer on a screen in the main rail station and its digital counterparts, such as ...

Multiple-View Scenes: Reconstruction and Virtual Views

Michel Bierlaire, Jean-Philippe Thiran, Javier Cruz Mota

The problem of generating a virtual view of a scene, i.e. a view from a point where there is not a physical camera to capture the scene, has received recently a lot of attention from the computer vision community. This is probably due to the increase of th ...

Single-Photon Synchronous Detection

Edoardo Charbon, Ties Jan Henderikus Kluter, Cristiano Niclass, Claudio Favi, Frédéric Monnier

A novel imaging technique is proposed for fully digital detection of phase and intensity of light. A fully integrated camera implementing the new technique was fabricated in a 0.35μm CMOS technology. When coupled to a modulated light source, the camera can ...

Colouring the near infrared

Sabine Süsstrunk

Current digital camera sensors are inherently sensitive to the near-infrared part of the spectrum. To prevent the near-IR contamination of images, an IR blocking filter (hot mirror) is placed in front of the sensor. In this work, we start by replacing the ...

MOEMS thermal imaging camera

Muhammed Fatih Toy, Onur Ferhanoglu

A novel thermo-mechanical Infrared (IR) imaging array with integrated diffraction gratings for optical readout was fabricated and tested. Parylene was used as a structural material for its low thermal conductivity and high thermal expansion properties. Tes ...

Multi-Camera Tracking and Atypical Motion Detection with Behavioral Maps

Pascal Fua, François Fleuret, Jérôme Berclaz

We introduce a novel behavioral model to describe pedestrians motions, which is able to capture sophisticated motion patterns resulting from the mixture of different categories of random trajectories. Due to its simplicity, this model can be learned from v ...

Multiscale video applied to surveillance and video conferencing systems

David Leroux

In the following study is presented two research works: the first is concerned with the elaboration of an intelligent meeting room while the second is about the development of a real time high definition video server capable of advanced accessibility optio ...

Multi-Camera People Tracking with a Probabilistic Occupancy Map

Pascal Fua, François Fleuret, Jérôme Berclaz

Given two to four synchronized video streams taken at eye level and from different angles, we show that we can effectively combine a generative model with dynamic programming to accurately follow up to six individuals across thousands of frames in spite of ...

Understanding Metro Station Usage using Closed Circuit Television Cameras Analysis

Jean-Marc Odobez

In this paper, we propose to show how video data available in standard CCTV transportation systems can represent a useful source of information for transportation infrastructure management, optimization and planning if adequately analyzed (e.g. to facilita ...
