Space-Time Extension of the MEM Approach for Electromagnetic Neuroimaging
Marie-Christine Roubaud, Jean-Marc Lina, Julie Carrier +1
The wavelet Maximum Entropy on the Mean (wMEM) approach to the MEG inverse problem is revisited and extended to infer brain activity from full space-time data. The resulting dimens…
Spectral analysis for nonstationary audio
Adrien Meynard, Bruno Torrésani
A new approach for the analysis of nonstationary signals is proposed, with a focus on audio applications. Following earlier contributions, nonstationarity is modeled via stationari…
Time-frequency and time-scale analysis of deformed stationary processes, with application to non-stationary sound modeling
H Omer, B Torrésani
A class of random non-stationary signals termed timbre x dynamics is introduced and studied. These signals are obtained by non-linear transformations of sta-tionary random gaussian…
Optimal Window and Lattice in Gabor Transform Application to Audio Analysis
Helene Lachambre, Benjamin Ricaud, Guillaume Stempfel +3
This article deals with the use of optimal lattice and optimal window in Discrete Gabor Transform computation. In the case of a generalized Gaussian window, extending earlier contr…
An optimally concentrated Gabor transform for localized time-frequency components
Benjamin Ricaud, Guillaume Stempfel, Bruno Torrésani +3
Gabor analysis is one of the most common instances of time-frequency signal analysis. Choosing a suitable window for the Gabor transform of a signal is often a challenge for practi…
Determining Local Transientness of Audio Signals
Stéphane Molla, Bruno Torrésani
We describe a new method for estimating the degree of "transientness" and "tonality" of a class of compound signals involving simultaneously transient and harmonic features. The ke…
