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.

Accurate Face Models from Uncalibrated and Ill-Lit Video Sequences

Pascal Fua, Slobodan Ilic, Miodrag Dimitrijevic

In this paper, we propose a face reconstruction technique that produces models that not only look good when texture mapped, but are also metrically accurate. Our method is designed to work with short uncalibrated video or movie sequences, even when the lig ...

Optic-flow-based Navigation for Ultralight Indoor Aircraft

Dario Floreano, Jean-Christophe Zufferey

The goal of this project is to develop an autonomous microflyer capable of navigating within houses or small built environments using vision as main source of information. Flying indoor implies a number of challenges that are not found in outdoor autonomou ...

A Prediction Model for Reflection on Varnished Metallic Plates

Roger Hersch, Mathieu Hébert, Patrick Emmel

Several models predict the reflectance of a rough metallic surface. They are however not adapted to the surfaces used in the packaging industry, such as boxes made of printed metallic plates. For printing purposes, metallic surfaces need to be varnished. L ...

Splines and wavelets for image warping and projection

Stefan Horbelt

This thesis investigates advanced signal processing concepts and their application to geometric processing and transformations of images and volumes. In the first part, we discuss the class of transformations that project volume data onto a plane using par ...

Gridella: A self-organizing P2P system

Karl Aberer, Manfred Hauswirth, Roman Schmidt

This paper describes our Gnutella compatible P2P system Gridella which is based on the P-Grid approach. P-Grid has several advantages over the standard Gnutella infrastructure, for example, that probabilistic estimates can be given for successful search re ...

Texture Mapping by Successive Refinement

Michaël Unser, Philippe Thévenaz

We define texture mapping as an optimization problem for which the goal of preserving the maximum amount of information in the mapped texture. We derive a solution that is optimal in the least-squares sense and that corresponds to the pseudo-inverse of a ...

Spatial Data Mapping with Support Vector Regression

The paper deals with the novel application of Support Vector Regression (SVR) for the analysis and modelling of spatially distributed environmental data. Mapping of soil pollution is considered as a real case study. Variography is widely used to control th ...

Design of a Survivable WDM Photonic Network

Jean-Yves Le Boudec, Olivier Crochat

Schemes - Hardware duplication or Mapping algorithm - for protecting a network using a Wavelength Division Multiplexing (WDM) infrastructure against component or link failures. ...

Artistic screening

Roger Hersch

Artistic screening is a new image reproduction technique incorporating freely created artistic screen elements for generating halftones. Fixed predefined dot contours associated with given intensity levels determine the screen dot shape's growing behavior. ...
