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.

Motion models for robust 3D human body tracking

Raquel Urtasun

In this work, we propose new ways to learn pose and motion priors models and show that they can be used to increase the performance of 3D body tracking algorithms, resulting in very realistic motions under very challenging conditions. We first explored an ...

Tracking the Multi Person Wandering Visual Focus of Attention

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba, Kevin Smith

Estimating the {\em wandering visual focus of attention} (WVFOA) for multiple people is an important problem with many applications in human behavior understanding. One such application, addressed in this paper, monitors the attention of passers-by to outd ...

A Robust Finger Tracking Method for Multimodal Wearable Computer Interfacing

Ali H. Sayed

Mobile wearable computers are intended to provide users with real-time access to information in a natural and unobtrusive manner. Computing and sensing in these devices must be reliable, easy to interact with, transparent, and configured to support differe ...

Kernel Methods for Melanoma Recognition

Barbara Caputo, Tatiana Tommasi

Malignant melanoma is the most deadly for of skin lesion. Early diagnosis is of critical importance to patient survival. Visual recognition algorithms could potentially be of great help for physicians in a computer assisted diagnosis system. Previous work ...

Pattern Detection by Distributed Feature Extraction

Pascal Frossard, Effrosyni Kokiopoulou

This paper presents a distributed algorithm for the detection of patterns or their transformed versions, in noisy images. The proposed method projects the observed signal onto a redundant and structured dictionary of functions, which are distributed among ...

Robust on-line adaptive footplant detection and enforcement for locomotion

Daniel Thalmann, Ronan Boulic, Pascal Glardon

A common problem in virtual character computer animation concerns the preservation of the basic foot-floor constraint (or footplant), consisting in detecting it before enforcing it. This paper describes a system capable of generating motion while continuou ...

An Approach to Multimodal Image Segmentation

Dominique Zosso

Radiotherapy treatment planning requires exact delineation of tumors in acquired images. Further, motion and deformation of a tumor due to respiratory movements must be known in order to better target and dose the treatment radiation. Here we present and i ...

SVM-based Transfer of Visual Knowledge Across Robotic Platforms

Barbara Caputo, Jie Luo

This paper presents an SVM--based algorithm for the transfer of knowledge across robot platforms aiming to perform the same task. Our method exploits efficiently the transferred knowledge while updating incrementally the internal representation as new inf ...

Teaching a Humanoid Robot to Recognize and Reproduce Social Cues

Aude Billard, Sylvain Calinon

In a Robot Programming by Demonstration framework, several demonstrations of a task are required to generalize and reproduce the task under different circumstances. To teach a task to the robot, explicit pointers are required to signal the start/end of a d ...
