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.

Analysis of the influence of the normal zone propagation velocity on the design of resistive fault current limiters

Daniele Colangelo, Bertrand Dutoit

Commercial high-temperature superconducting coated conductors (HTS-CCs) have low thermal diffusivity and nonuniform critical current density. These two factors lead commercial HTS-CCs to a partial quench when they are subjected to a transport current aroun ...

Schizophrenia and visual backward masking: a general deficit of target enhancement

Michael Herzog, Maya Roinishvili

The obvious symptoms of schizophrenia are of cognitive and psychopathological nature. However, schizophrenia affects also visual processing which becomes particularly evident when stimuli are presented for short durations and are followed by a masking stim ...

Multi-pose lipreading and audio-visual speech recognition

Jean-Philippe Thiran, Virginia Estellers Casas

In this article, we study the adaptation of visual and audio-visual speech recognition systems to non-ideal visual conditions. We focus on overcoming the effects of a changing pose of the speaker, a problem encountered in natural situations where the speak ...

Dynamics of Visual Feature Integration and Decision Making

Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. These features are integrated in subsequent stages of the visual hierarchy. Generally it is assumed that the information about these basic features is lost once the information is s ...

OmniSIFT: Scale Invariant Features in Omnidirectional Images

Pascal Frossard, Zafer Arican

We propose a method to compute scale invariant features in omnidirectional images. We present a formulation based on Riemannian geometry for the definition of differential operators on non-Euclidian manifolds that correspond to the particular form of mirro ...

Automatic grouping of regular structures

Michael Herzog, Frank Scharnowski

To cope with the continuously incoming stream of input, the visual system has to group information across space and time. Usually, spatial and temporal grouping are investigated separately. However, recent findings revealed that these two grouping mechanis ...

The temporal dynamics of visual feature integration.

Johannes Rüter

Vision is dynamic. After their onset, visual stimuli undergo a complex cascade of processes before awareness is reached. Even after more than a century of research, the timing of these processes is still largely unknown. In particular, how the brain determ ...

Long-lasting modulation of feature integration by transcranial magnetic stimulation

Michael Herzog, Frank Scharnowski, Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. On the objects way to a conscious percept, these features are integrated in subsequent stages of the visual hierarchy. The time course of this feature integration is largely unknown ...

SELECTING RELEVANT VISUAL FEATURES FOR SPEECHREADING

Jean-Philippe Thiran, Mihai Gurban, Virginia Estellers Casas

A quantitative measure of relevance is proposed for the task of constructing visual feature sets which are at the same time relevant and compact. A feature's relevance is given by the amount of information that it contains about the problem, while compactn ...

Adaptive visual attention model

Heinz Hügli, Alexandre Bur

Visual attention, defined as the ability of a biological or artificial vision system to rapidly detect potentially relevant parts of a visual scene, provides a general purpose solution for low level feature detection in a vision architecture. Well consider ...
