Gridless 2D Recovery of Lines using the Sliding Frank-Wolfe Algorithm
We present a new approach leveraging the Sliding Frank--Wolfe algorithm to address the challenge of line recovery in degraded images.
Instantaneous Frequency Estimation in Multicomponent Signals in Case of Interference Based on the Prony Method
In this paper, we develop a general method to estimate the instantaneous frequencies of the modes making up a multicomponent signal when the former exhibit interference in the time-frequency plane.
Unsupervised classification of the spectrogram zeros
In this work, a classification of these zeros in three types is introduced, based on the nature of the components that interfere to produce them.
Instantaneous Frequency Estimation In Multi-Component Signals Using Stochastic EM Algorithm
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 Ridge Detector for Nonstationary Multicomponent Signals: Development and Application to Robust Mode Retrieval
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.
Robust 3D reconstruction of dynamic scenes from single-photon lidar using Beta-divergences
In this work, we consider a new similarity measure for robust depth estimation, which allows us to use a simple observation model and a non-iterative estimation procedure while being robust to mis-specification of the background illumination model.
