Instantaneous Frequency Estimation in Noisy Multicomponent Signals with Interfering Modes Based on Prony Method and Spline Approximation
Basile Dubois-Bonnaire, Sylvain Meignen, Kévin Polisano
In this paper, we propose a novel estimator of the instantaneous frequencies (IFs) of the modes making up multicomponent signals (MCSs). We are particularly interested in dealing w…

Gridless 2D Recovery of Lines using the Sliding Frank-Wolfe Algorithm
Kévin Polisano, Basile Dubois-Bonnaire, Sylvain Meignen
We present a new approach leveraging the Sliding Frank--Wolfe algorithm to address the challenge of line recovery in degraded images. Building upon advances in conditional gradient…

Instantaneous Frequency Estimation in Multicomponent Signals in Case of Interference Based on the Prony Method
Basile Dubois-Bonnaire, Sylvain Meignen, Kévin Polisano
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…
