Geometric Video Approximation Using Weighted Matching Pursuit

Michel Bierlaire, Pierre Vandergheynst, Oscar Divorra Escoda, Gianluca Monaci

In recent years, many works on geometric image representation have appeared in the literature. Geometric video representation has not received such an important attention so far, and only some initial works in the area have been presented. Works on geometr ...

Analysis of Multimodal Sequences Using Geometric Video Representations

Pierre Vandergheynst, Oscar Divorra Escoda, Gianluca Monaci

This paper presents a novel method to correlate audio and visual data generated by the same physical phenomenon, based on sparse geometric representation of video sequences. The video signal is modeled as a sum of geometric primitives evolving through time ...

Ventricular and Atrial Activity Estimation Through Sparse ECG Signal Decompositions

Jean-Marc Vesin, Pierre Vandergheynst, Oscar Divorra Escoda, Lorenzo Granai, Mathieu Lemay

This paper explores a novel approach for ventricular and atrial activities estimation in electrocardiogram (ECG) signals, based on sparse source separation. Sparse decompositions of ECG over signal-adapted multi-component dictionaries can lead to natural s ...
