National audience; Nous considérons le problème de filtrage adaptatif de données sismiques composées : de signaux d'intérêts ("primaires"), de perturbations structurées correspondant à des propagations d'ondes présentant des réflexions mult

This thesis deals with two different problems within the framework of convex and non convex optimization. The first one is an application to multiple removal in seismic data with adaptive filters and the second one is an application to blind deconvol

International audience; The ℓ 1 /ℓ 2 ratio regularization function has shown good performance for retrieving sparse signals in a number of recent works, in the context of blind deconvolution. Indeed, it benefits from a scale invariance property m

International audience; Both random and structured perturbations affect seismic data. Their removal, to unveil meaningful geophysical information, requires additional priors. Seismic multiples are one form of structured perturbations related to wave-
