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.

Polygon Mesh Processing

Mark Pauly

Geometry processing, or mesh processing, is a fast-growing area of research that uses concepts from applied mathematics, computer science, and engineering to design efficient algorithms for the acquisition, reconstruction, analysis, manipulation, simulatio ...

Modélisation géométrique itérative sous contraintes

Gilles Gouaty

Iterative models are widely used today in CAD. They allow, with a limited number of parameters, to represent relatively complex forms through a subdivision algorithm. There is a wide variety of such models (Catmull-Clark, Doo-Sabin, L-Systems...). Most ite ...

Deformable Surface 3D Reconstruction from Monocular Images

Pascal Fua, Mathieu Salzmann

Being able to recover the shape of 3D deformable surfaces from a single video stream would make it possible to field reconstruction systems that run on widely available hardware without requiring specialized devices. However, because many different 3D shap ...

3D Object Duplicate Detection for Video Retrieval

Touradj Ebrahimi, Jong Seok Lee, Lutz Goldmann, Ivan Ivanov, Péter Vajda

Content-based video retrieval has become a very active research area in the last decade due to the increasing number of video shared on social networks such as YouTube and Daily-Motion. While most of the content-based video retrieval approaches employ visu ...

Real-Time Update of 3D Deformable Models for Computer Aided Liver Surgery

Charles Baur, Benoît Dagon

Providing accurate image-guidance for soft-tissue interventions remains a complex task. Most of the time, preoperative models and planning data are no more valid during the surgical process due to motions and deformations of the organ of interest. In this ...

Estimating Hip Joint Contact Pressure from Geometric Features

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

Hip mechanical simulation for estimating pressures within the soft tissues during the loads and motions of daily activities is a common approach to investigate hip joint pathology. Many computational approaches estimate the pressure and contact pressures v ...

Thick-film multi-DOF force / torque sensor for wrist rehabilitation

Thomas Maeder, Caroline Jacq, Roger Gassert, Olivier Lambercy, Barthélémy Lüthi

A complete six–degree-of-freedom (6-DOF) force / torque sensor has been designed and fabricated for wrist rehabilitation applications, with the focus laid on simple, straightforward manufacturing processes. This paper details the mechanical design, 3D-mode ...

Modeling complex intersections with the cell-transmission model

Gunnar Flötteröd

This article widens the scope of the cell-transmission model (CTM) to the modeling of urban traffic, which is dominated by intersection dynamics. The CTM has originally been proposed for freeways, and it is not immediately applicable to urban traffic for t ...

Template-Free Monocular Reconstruction of Deformable Surfaces

Pascal Fua, Mathieu Salzmann, Engin Tola, Aydin Varol

It has recently been shown that deformable 3D surfaces could be recovered from single video streams. However, existing techniques either require a reference view in which the shape of the surface is known a priori, which often may not be available, or requ ...

Beltrami-Flow to Generate a Scale-Space of Cortical Feature Maps on the Sphere.

Jean-Philippe Thiran, Dominique Zosso

In this paper we define a scale-space for cortical mean curvature maps on the sphere, that offers a hierarchical representation of the cortical structures, useful in multi-scale algorithms. A spherical feature map is obtained through inflation of the corti ...
