A Variational EM Algorithm for the Separation of Time-Varying Convolutive Audio Mixtures
Dionyssos Kounades-Bastian, Laurent Girin, Xavier Alameda-Pineda +2
This paper addresses the problem of separating audio sources from time-varying convolutive mixtures. We propose a probabilistic framework based on the local complex-Gaussian model…
An On-line Variational Bayesian Model for Multi-Person Tracking from Cluttered Scenes
Sileye Ba, Xavier Alameda-Pineda, Alessio Xompero +1
Object tracking is an ubiquitous problem that appears in many applications such as remote sensing, audio processing, computer vision, human-machine interfaces, human-robot interact…
EM Algorithms for Weighted-Data Clustering with Application to Audio-Visual Scene Analysis
Israel D. Gebru, Xavier Alameda-Pineda, Florence Forbes +1
Data clustering has received a lot of attention and numerous methods, algorithms and software packages are available. Among these techniques, parametric finite-mixture models play…
SALSA: A Novel Dataset for Multimodal Group Behavior Analysis
Xavier Alameda-Pineda, Jacopo Staiano, Ramanathan Subramanian +5
Studying free-standing conversational groups (FCGs) in unstructured social settings (e.g., cocktail party ) is gratifying due to the wealth of information available at the group (m…
