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.

Introduction of cylinder quality measure into Minutia Cylinder-Code based fingerprint matching

Leila Mirmohamadsadeghi, Andrzej Drygajlo, Mohammad Hamed Izadi

Poor data quality is responsible for many or even most matching errors in fingerprint recognition systems. It became obvious that particular effort is needed in adaptation of the state-of-the-art minutiae-based fingerprint matching techniques to real-world ...

Automatic text detection for mobile augmented reality translation

Charles Baur, Marc Petter

We present a fast automatic text detection algorithm devised for a mobile augmented reality (AR) translation system on a mobile phone. In this application, scene text must be detected, recognized, and translated into a desired language, and then the transl ...

Using Life Cycle Approaches to Enhance the Value of Corporate Environmental Disclosures

Damien Antoine Friot

As the focus of environmental policy and management shifts from cleaner production at the process level towards greener products as a whole, stakeholders ask for transparency throughout the entire value chain. This article assesses the comprehensiveness an ...

Collaborative Gaze Footprints: Correlates of Interaction Quality

Pierre Dillenbourg, Patrick Jermann, Marc-Antoine Nüssli

Dual eye tracking offers new possibilities for the analysis and diagnosis of collaborative interaction. Cross-recurrence analyses and visualizations offer insight into how closely two collaborators’ gaze follow each other. We contrast two cases to illustra ...

A starter kit for point-localization super-resolution imaging

Suliana Manley, Julia Gunzenhäuser

Super-resolution fluorescence imaging can be achieved through the localization of single molecules. By using suitable dyes, optical configurations, and software, it is possible to study a wide variety of biological systems. Here, we summarize the different ...

Enhanced Wavefield Separation of OBS Data

Loïc Arnaud Baboulaz

In ocean-bottom seismic (OBS) data processing, wavefield separation results are sometimes affected by high levels of noise on the vertical component Z, while the pressure component P is in general of good quality. Nonetheless, Z is needed to achieve comple ...

Multi-slice 2D MR imaging: automatic assessment of image quality

Jean-Philippe Thiran

We describe a method for the automatic quality assessment of multi-slice 2D MRIs with FLAIR, T2, or PD contrast. Quality measures are derived by analyzing the air background, which can be used to sensitively detect typical motion artifacts. Validated on 42 ...

A union of incoherent spaces model for classification

Pierre Vandergheynst, Karin Schnass

We present a new and computationally efficient scheme for classifying signals into a fixed number of known classes. We model classes as subspaces in which the corresponding data is well represented by a dictionary of features. In order to ensure low miscla ...

In-flight quality assessment and data processing for airborne laser scanning

Philipp Schär

One of the main problems of today's Airborne Laser Scanning (ALS) systems is the lack of reliable data QA/QC (Quality Assurance/ Quality Control) within or shortly after the airborne survey campaign. This thesis presents the development of methods to perfo ...

Analyzing Trust Management Impact to Optimal Adversarial Attacks in Recommender Systems

Karl Aberer, Hung Le Vu

Ranking systems, such as those in product review sites, and various recommender systems usually employ user ratings to rank favorite items based on their quality and/or popularity. Since higher ranked items are more likely to be selected by customers and t ...
