This report presents a semi-supervised method to jointly extract audio-visual sources from a scene. It consist of applying a supervised method to segment the video signal followed by an automatic process to properly separate the audio track. This approach ...
The following coding scenario is addressed: A number of audio source signals need to be transmitted or stored for the purpose of mixing wave field synthesis, multi channel surround, or stereo signals after decoding the source signals. The proposed techniqu ...
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 ...
We present a compact 3 degrees of freedom (dof) (X-Y-θz) absolute position sensor offering a sub-micrometric resolution. The travelling range is 15x15mm2 (translations) and ±180° (rotation), with an absolute precision better than 10μm over the whole travel ...

An encoder/decoder for multi-channel audio data, and in particular for audio reproduction through wave field synthesis. The encoder comprises a two-dimensional filter-bank to the multi-channel signal, in which the channel index is treated as an independent ...
This paper addresses the multimodal nature of social dominance and presents multimodal fusion techniques to combine audio and visual nonverbal cues for dominance estimation in small group conversations. We combine the two modalities both at the feature ext ...
In this paper, we propose for the first time the application of ambipolar CNTFETs with in-field controllable polarities to design regular fabrics with static logic. We exploit the high expressive power provided by complementary static logic built with ambi ...
This paper presents a novel concept for a compact low-cost Earth sensor based on imaging atmospheric oxygen emission at 762nm using arrays of single photon avalanche diodes (SPADs). In both nighttime and daytime there is continuous emission at 762nm due to ...

A theoretical and experimental analysis of the impact of pulse modulation format on Brillouin optical time-domain analysis (BOTDA) sensors using pulse coding techniques has been carried out. Pulse coding with conventional non-return-to-zero (NRZ) modulatio ...
