Data driven sampling of oscillating signals
Brigitte Bidégaray-Fesquet, Marianne Clausel
The reduction of the number of samples is a key issue in signal processing for mobile applications. We investigate the link between the smoothness properties of a signal and the nu…
Self-Similar Anisotropic Texture Analysis: the Hyperbolic Wavelet Transform Contribution
S. G. Roux, M. Clausel, B. Vedel +2
Textures in images can often be well modeled using self-similar processes while they may at the same time display anisotropy. The present contribution thus aims at studying jointly…
A strong optimality result for anisotropic self--similar textures
M. Clausel, B. Vedel
In previous works, we proposed a method to characterize jointly self-similarity and anisotropy properties of a large class of self--similar Gaussian random fields. We provide here…
An optimality result about sample path properties of Operator Scaling Gaussian Random Fields
M. Clausel, B. Vedel
We study the sample paths properties of Operator scaling Gaussian random fields. Such fields are anisotropic generalizations of anisotropic self-similar random fields as anisotropi…
Sample paths properties of Gaussian fields with equivalent spectral densities
M. Clausel, B. Vedel
We prove that if and are two Gaussian fields with equivalent spectral densities, they have the same sample paths properties in any separable Banach space continuously embed…
