FORBID: Fast Overlap Removal By stochastic gradIent Descent for Graph Drawing
Loann Giovannangeli, Frederic Lalanne, Romain Giot +1
While many graph drawing algorithms consider nodes as points, graph visualization tools often represent them as shapes. These shapes support the display of information such as labe…
Deep Neural Network for DrawiNg Networks, (DNN)^2
Loann Giovannangeli, Frederic Lalanne, David Auber +2
By leveraging recent progress of stochastic gradient descent methods, several works have shown that graphs could be efficiently laid out through the optimization of a tailored obje…
Impacts of the Numbers of Colors and Shapes on Outlier Detection: from Automated to User Evaluation
Loann Giovannangeli, Romain Giot, David Auber +1
The design of efficient representations is well established as a fruitful way to explore and analyze complex or large data. In these representations, data are encoded with various…
Toward automatic comparison of visualization techniques: Application to graph visualization
L. Giovannangeli, R. Bourqui, R. Giot +1
Many end-user evaluations of data visualization techniques have been run during the last decades. Their results are cornerstones to build efficient visualization systems. However,…
CNNs Fusion for Building Detection in Aerial Images for the Building Detection Challenge
Rémi Delassus, Romain Giot
This paper presents our contribution to the DeepGlobe Building Detection Challenge. We enhanced the SpaceNet Challenge winning solution by proposing a new fusion strategy based on…
Web-Based Benchmark for Keystroke Dynamics Biometric Systems: A Statistical Analysis
Romain Giot, Mohamad El-Abed, Christophe Rosenberger
Most keystroke dynamics studies have been evaluated using a specific kind of dataset in which users type an imposed login and password. Moreover, these studies are optimistics sinc…
Hybrid Template Update System for Unimodal Biometric Systems
Romain Giot, Christophe Rosenberger, Bernadette Dorizzi
Semi-supervised template update systems allow to automatically take into account the intra-class variability of the biometric data over time. Such systems can be inefficient by inc…
Local Water Diffusion Phenomenon Clustering From High Angular Resolution Diffusion Imaging (HARDI)
Romain Giot, Christophe Charrier, Maxime Descoteaux
The understanding of neurodegenerative diseases undoubtedly passes through the study of human brain white matter fiber tracts. To date, diffusion magnetic resonance imaging (dMRI)…
Genetic Programming for Multibiometrics
Romain Giot, Christophe Rosenberger
Biometric systems suffer from some drawbacks: a biometric system can provide in general good performances except with some individuals as its performance depends highly on the qual…
Performance Evaluation of Biometric Template Update
Romain Giot, Christophe Rosenberger, Bernadette Dorizzi
Template update allows to modify the biometric reference of a user while he uses the biometric system. With such kind of mechanism we expect the biometric system uses always an up…
Fast computation of the performance evaluation of biometric systems: application to multibiometric
Romain Giot, Mohamad El-Abed, Christophe Rosenberger
The performance evaluation of biometric systems is a crucial step when designing and evaluating such systems. The evaluation process uses the Equal Error Rate (EER) metric proposed…
Keystroke Dynamics Authentication For Collaborative Systems
Romain Giot, Mohamad El-Abed, Christophe Rosenberger
We present in this paper a study on the ability and the benefits of using a keystroke dynamics authentication method for collaborative systems. Authentication is a challenging issu…
