Unveiling meaningful geophysical information from seismic data requires to deal with both random and structured “noises”. As their amplitude may be greater than signals of interest (primaries), additional prior information is especially important in performing efficient signal separation. We address here the problem of multiple reflections, caused by wave-field bouncing between layers. Since only approximate models of these phenomena are available, we propose a flexible framework for time…

A constrained-based optimization approach for seismic data recovery problems
Within this framework, the criterion to be minimized mainly consists of a data fidelity term and hard constraints modeling a priori information, which may avoid, or at least facilitate, some parameter determination tasks, usually difficult to perform in inverse problems.
Seismic wave field restoration using spare representations and quantitative analysis. (Représentation parcimonieuses pour la restauration et l'analyse quantitative de champs d'ondes en sismiques)
A proximal-based algorithm to solve variational problems involving this function and the main idea of this work is to use an additional premise that the reflections occur as sparsely restricted, for which a study on the "sparsity measure" is considered.

Signal separation in convolutive mixtures : contributions to blind separation of sparse sources and adaptive subtraction of seismic multiples
This work addresses the necessary and sufficient conditions for the exact extraction and separation of sparse sources by using the L0 pseudo-norm as a contrast function and proposes to improve the robustness of adaptive subtraction by estimating the extracting convolutive filters directly in the curvelet domain.

This work proposes an accelerating ICT method by exploiting the misfit between the original and estimated signals in curvelet domain directly, and introduces the joint constraints within different frequency bands to stabilize and improve the multiple attenuation.


Seismic multiple removal with a primal-dual proximal algorithm
This paper recast the problem of jointly estimating the filters and the signal of interest (primary) in a new convex variational formulation, allowing the incorporation of knowledge about the noise statistics, and designs a primal-dual algorithm which yields good performance in the provided simulation examples.
A convex variational approach for multiple removal in seismic data
It is shown that estimating multiples is equivalent to identifying filters and a new variational framework based on Maximum A Posteriori (MAP) estimation is proposed to solve the problem of multiple removal.
A Fast and Automatic Sparse Deconvolution in the Presence of Outliers
An efficient deconvolution method to retrieve sparse reflectivity series from seismic data in the presence of additive Gaussian and non-Gaussian noise is presented and automatically generates high-resolution solutions by only a few iterations needless of any prior knowledge about the noise in the data.
An Augmented Lagrangian Approach to the Constrained Optimization Formulation of Imaging Inverse Problems
This paper proposes a new efficient algorithm to handle one class of constrained problems (often known as basis pursuit denoising) tailored to image recovery applications and shows that the proposed algorithm is a strong contender for the state-of-the-art.
A sparse adaptive filtering using time-varying soft-thresholding techniques
A novel adaptive filtering algorithm based on an iterative use of the proximity operator and the parallel variable-metric projection and the (weighted) ℓ1 norm as the penalty term, leading to a time-varying soft-thresholding operator is proposed.

Solving inverse problems with overcomplete transforms and convex optimization techniques
How the choice of the transform may influence parameters and operators necessary to implement algorithms is discussed, including convex optimization approaches that consist of minimizing a criteria generally composed of two terms: a data fidelity term and a prior term.
