Let $(X,Y)\in\mathcal{X}\times \mathcal{Y}$ be a random couple with unknown distribution $P$. Let $\GG$ be a class of measurable functions and $\ell$ a loss function....

We propose in this thesis a new type of wavelet transform, the dual-tree M-band wavelet decomposition, that has some unique geometrical features. This type of wavelet...

Reflected waves carry information about the position, shape and physical properties of the geological discontinuities that originate them. The Ray+Born preserved...

Nous présentons une méthodologie basée sur les chaînes de Markov cachées pour la modélisation et l'analyse statistique de courbes de consommation électrique. Suite à...

With an initial formation in theoretical computer sciences with a focus on image processing and analysis, my current research activities deal with image and...

The deconvolution of blurred and noisy satellite images is an ill-posed inverse problem, which can be regularized within a Bayesian context by using an a priori model...

The deconvolution of blurred and noisy satellite images is an ill-posed inverse problem. The direct inversion leads to unacceptable noise amplificatio- n. Usually,...

The pre-stack depth migration of reflection seismic data can be expressed, with the framework of waveform inversion, as a linear least squares problem. While defining...

The aim of this study is to consider couples of basins and their respective non-calibrated robust geomorphology-based transfer functions. In the frame of discharge...
