Distributed multi-view image coding with learned dictionaries

This paper addresses the problem of distributed image coding in camera neworks. The correlation between multiple images of a scene captured from different viewpoints can be effiiciently modeled by local geometric transforms of prominent images features. Su ...

Binaural reverberation using a modified Jot reverberator with frequency- dependent interaural coherence matching

Christof Faller, Fritz Menzer

An extension of the Jot reverberator is presented, producing binaural late reverberation where the interaural coherence can be controlled as a function of frequency such that it matches the frequency-dependent interaural coherence of a reference binaural r ...

Designing Practical Filters For Sound Field Reconstruction

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Multichannel sound field reproduction techniques, such as Wave Field Synthesis (WFS) and Sound Field Reconstruction (SFR), define loudspeaker filters in the frequency domain. However, in order to use these techniques in practical systems, one needs to conv ...

Beamforming with a Maximum Negentropy Criterion

Philip Neil Garner, Weifeng Li

In this paper, we address a beamforming application based on the capture of far-field speech data from a single speaker in a real meeting room. After the position of the speaker is estimated by a speaker tracking system, we construct a subband-domain beamf ...

Intermediate view generation for perceived depth adjustment of stereo video

Zafer Arican

There is significant industry activity on delivery of 3D video to the home. It is expected that 3D capable devices will be able to provide consumers with the ability to adjust the depth perceived for stereo content. This paper provides an overview of relat ...

Investigation of high-resolution functional magnetic resonance imaging by means of surface and array radiofrequency coils at 7 T

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

In this investigation, high-resolution, 1x1x1-mm(3) functional magnetic resonance imaging (fMRI) at 7 T is performed using a multichannel array head coil and a surface coil approach. Scan geometry was optimized for each coil separately to exploit the stren ...

Rate-Constrained Collaborative Noise Reduction for Wireless Hearing Aids

Martin Vetterli, Olivier Roy

Hearing aids are electronic, battery-operated sensing devices which aim at compensating various kinds of hearing impairments. Recent advances in low-power electronics coupled with progresses made in digital signal processing offer the potential for substan ...

Thanks to geolocalized remote control : the sound will follow

Daniel Thalmann, Frédéric Vexo, Mathieu Hopmann

Dematerialized music and MP3 players offer to the user the possibility of carrying his musical content everywhere. However, at home, the music collection is generally not centralized, split between different rooms and audio supports (CDs, MP3s, etc). In th ...

Comparison of three commercially available radio frequency coils for human brain imaging at 3 Tesla

Rolf Gruetter, Wietske Van der Zwaag, Andreas Joosten

Objective To evaluate a transverse electromagnetic (TEM), a circularly polarized (CP) (birdcage), and a 12-channel phased array head coil at the clinical field strength of B (0) = 3T in terms of signal-to-noise ratio (SNR), signal homogeneity, and maps of ...

Maximum kurtosis beamforming with the generalized sidelobe canceller

Philip Neil Garner, John David Scott Dines, Weifeng Li

This paper presents an adaptive beamforming application based on the capture of far-field speech data from a real single speaker in a real meeting room. After the position of a speaker is estimated by a speaker tracking system, we construct a subband-domai ...
