Design and Control of an Indoor Coaxial Helicopter

This paper presents the design and preliminary control of an indoor coaxial helicopter �CoaX� based on a concept of hybrid active and passive control. The robot is capable of passive roll and pitch stabilization against small disturbances while a ...

Improved Time Delay Analysis/Synthesis for Parametric Stereo Audio Coding

Christof Faller, Christophe Tournery

For parametric stereo and multi-channel audio coding, it has been proposed to use level difference, time difference, and coherence cues between audio channels to represent the perceptual spatial features of stereo and multi-channel audio signals. In practi ...

Combined Depth and Outlier Estimation in Multi-View Stereo

Christoph Strecha

In this paper, we present a generative model based approach to solve the multi-view stereo problem. The input images are considered to be generated by either one of two processes: (i) an inlier process, which generates the pixels which are visible from the ...

A Spectrogram Model for Enhanced Source Localization and Noise-Robust ASR

Guillaume Lathoud, Bertrand Mesot

This paper proposes a simple, computationally efficient 2-mixture model approach to discrimination between speech and background noise. It is directly derived from observations on real data, and can be used in a fully unsupervised manner, with the EM algor ...

AV16.3: an Audio-Visual Corpus for Speaker Localization and Tracking

Daniel Gatica-Perez, Jean-Marc Odobez, Guillaume Lathoud

Assessing the quality of a speaker localization or tracking algorithm on a few short examples is difficult, especially when the ground-truth is absent or not well defined. One step towards systematic performance evaluation of such algorithms is to provide ...

Parametric coding of spatial audio

Christof Faller

A wide range of techniques for coding a single speech or audio signal channel have been developed over the last few decades. In addition to pure redundancy reduction, sophisticated source and receiver models have been considered for reducing the bitrate. O ...

Acoustic Source Localization in Distributed Sensor Networks

Martin Vetterli, Thibaut Ajdler

This paper studies the problem of sound source localization in a distributed wireless sensor network formed by mobile general pur- pose computing and communication devices with audio I/O capa- bilities. In contrast to well understood localization methods b ...

Magic wand and the Enigma of the Sphinx

Daniel Thalmann, Olivier Renault, Frédéric Vexo, Tolga Abaci, Mireille Clavien, Jan Ciger

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application "The Enigma of the Sphinx". The interface consists of a large projection sc ...
