Unsupervised classification of the spectrogram zeros
Juan M. Miramont, François Auger, Marcelo A. Colominas +2
The zeros of the spectrogram have proven to be a relevant feature to describe the time-frequency structure of a signal, originated by the destructive interference between component…
Instantaneous Frequency Estimation In Multi-Component Signals Using Stochastic EM Algorithm
Quentin Legros, Dominique Fourer, Sylvain Meignen +1
This paper addresses the problem of estimating the modes of an observed non-stationary mixture signal in the presence of an arbitrary distributed noise. A novel Bayesian model is i…
A Novel Ridge Detector for Nonstationary Multicomponent Signals: Development and Application to Robust Mode Retrieval
Nils Laurent, Sylvain Meignen
Time-frequency analysis is often used to study non stationary multicomponent signals, which can be viewed as the surperimposition of modes, associated with ridges in the TF plane.…
High-Order Synchrosqueezing Transform for Multicomponent Signals Analysis -- With an Application to Gravitational-Wave Signal
Duong-Hung Pham, Sylvain Meignen
This study puts forward a generalization of the short-time Fourier-based Synchrosqueezing Transform using a new local estimate of instantaneous frequency. Such a technique enables…
Robust 3D reconstruction of dynamic scenes from single-photon lidar using Beta-divergences
Quentin Legros, Julian Tachella, Rachael Tobin +6
In this paper, we present a new algorithm for fast, online 3D reconstruction of dynamic scenes using times of arrival of photons recorded by single-photon detector arrays. One of t…
EM-based approach to 3D reconstruction from single-waveform multispectral Lidar data
Quentin Legros, Sylvain Meignen, Stephen McLaughlin +1
In this paper, we present a novel Bayesian approach for estimating spectral and range profiles from single-photon Lidar waveforms associated with single surfaces in the photon-limi…
Smoothness of Nonlinear and Non-Separable Subdivision Schemes
Basarab Matei, Sylvain Meignen, Anastasia Zakharova
We study in this paper nonlinear subdivision schemes in a multivariate setting allowing arbitrary dilation matrix. We investigate the convergence of such iterative process to some…
