Online Modulation of the Level of Assistance in Shared Control Systems

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Robert Leeb, Tom Edward Carlson

In this paper we propose a method to modulate the level of assistance provided by a shared controller, not only given the environmental context, but also according to the context of the user’s current behaviour. We show that the enhanced situational contex ...

Video-Based In Situ Tagging on Mobile Phones

Vincent Lepetit

We propose a novel way to augment a real-world scene with minimal user intervention on a mobile phone; the user only has to point the phone camera to the desired location of the augmentation. Our method is valid for horizontal or vertical surfaces only, bu ...

Upscaling of a two-region façade-leaching model to the city scale

David Andrew Barry, Luca Rossi, Sylvain Coutu, Dario Del Giudice

Painted facades are protected by paints that contain biocides as a protection against degradation. These facades are leached of biocides by rainfall, albeit at low concentrations. Nevertheless, at the city scale the leachable surface area of building facad ...

Immobilizing device for a toothed wheel

Simon Nessim Henein, Fabiano Colpo

The invention relates to an immobilizing device for a toothed wheel suitable for the field of horology where it can be part of a direct- or indirect-impulse escapement, in particular in a wristwatch. This immobilizing device (1, 2, 3, 4, 5, 6) comprises: — ...

Multistream Speaker Diarization beyond Two Acoustic Feature Streams

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

Speaker diarization for meetings data are recently converging towards multistream systems. The most common complementary features used in combination with MFCC are Time Delay of Arrival (TDOA). Also other features have been proposed although, there are no ...

Multi-layer Boosting for Pattern Recognition

François Fleuret

We extend the standard boosting procedure to train a two-layer classifier dedicated to handwritten character recognition. The scheme we propose relies on a hidden layer which extracts feature vectors on a fixed number of points of interest, and an output l ...

Writer Identification for Smart Meeting Room Systems

Samy Bengio, Jonas Richiardi

In this paper we present a text independent on-line writer identification system based on Gaussian Mixture Models (GMMs). This system has been developed in the context of research on Smart Meeting Rooms. The GMMs in our system are trained using two sets of ...

A new reinitialization procedure for the finite element approximation of the level set equation

Erik Burman, Nicola Parolini

In the past few years, the level set method has been extensively used for the numerical solution of interface problems in different domains, from free-surface and mean curvature flows to image processing. A crucial ingredient in every implementation of the ...
