Reduction of Fixed-Position Noise in Position-Sensitive, Single-Photon Avalanche Diodes

Edoardo Charbon, Matthew Fishburn

By ignoring events originating in noisy areas of a position-sensitive single-photon avalanche diode (SPAD), reduction of noise from fixed-position defects is experimentally shown. Additional experimental results from a position-sensitive SPAD integrated in ...

Realtime Performance-Based Facial Animation

Mark Pauly, Hao Li, Sofien Bouaziz

This paper presents a system for performance-based character animation that enables any user to control the facial expressions of a digital avatar in realtime. The user is recorded in a natural environment using a non-intrusive, commercially available 3D s ...

Noise reduction and estimation in multiple micro-electro-mechanical inertial systems

Jan Skaloud, Stéphane Guerrier, Adrian Wägli

This research studies the reduction and the estimation of the noise level within a redundant configuration of low-cost (MEMS-type) inertial measurement units (IMUs). Firstly, independent observations between units and sensors are assumed and the theoretica ...

Using measured instead of perceived noise in hedonic models

Philippe Thalmann, Andrea Baranzini, Caroline Schaerer

This paper compares the use of perceived and measured noise in a hedonic housing model. Although in theory the use of subjective variables is recommended, most empirical applications use measured noise variables. Merging different databases, we obtain a sa ...

Low noise DC to DC converters for the sLHC experiments

Stefano Michelis

The development of front-end systems for the ATLAS tracker at the sLHC is now in progress and the availability of radiation tolerant buck converter ASICs enables the implementation of DC to DC converter based powering schemes. The front-end systems powered ...

Dynamic noise modeling at roundabouts

Modeling spatial and temporal noise variations at roundabouts is a tedious task. Indeed, noise levels are strongly influenced by the complex vehicle interactions taking place at the entries. An accurate modeling of the merging process and its impact on veh ...

Active low-frequency modal noise cancellation for room acoustics: an experimental study

Hervé Lissek, Xavier Falourd, Pierre-Jean René

Low frequency background noise in rooms generated by numbers of human activities - traf-fic, railway, airport and industrial noise - creates major disturbances from loss of speech in-telligibility to stress and fatigue. To overcome such situations classica ...

Synchronous and Asynchronous Detection of Ultra-Low Light Levels

Peter Seitz, Christian Lotto

Comprehensive analysis of noise sources in photocharge detectors leads to two novel, compact pixel circuits for ultra-low-noise light detection using optimum bandwidth engineering. A synchronous 4T CMOS image sensor pixel with in-pixel amplification reache ...

Noise levels during nCPAP are flow-dependent but not device-dependent

Eric Van Lancker

Objective: Nasal continuous positive airway pressure (nCPAP) has been shown to improve the outcome of infants with respiratory distress syndrome. However, noise generation could be of concern. Therefore, our study was designed to measure the noise levels o ...

A multimodal pattern recognition framework for speaker detection

Patricia Besson

Speaker detection is an important component of a speech-based user interface. Audiovisual speaker detection, speech and speaker recognition or speech synthesis for example find multiple applications in human-computer interaction, multimedia content indexin ...
