A regularized nonlinear diffusion approach for texture image denoising
(2009-12-01)
In this paper a new partial differential equation based method is presented with a view to denoising images having textures. The proposed model combines a nonlinear anisotropic diffusion filter with recent harmonic analysis ...

Detecção de bordas em imagens digitais através de um processo de difusão anisotrópica não linear
(2006-12-01)
The edges detection model by a non-linear anisotropic diffusion, consists in a mathematical model of smoothing based in Partial Differential Equation (PDE), alternative to the conventional low-pass filters. The smoothing ...

Photorefractive writing and probing of anisotropic linear and nonlinear lattices
(IOP Publishing, 2015)
We study experimentally the writing of one- and two-dimensional photorefractive lattices, focusing on the often overlooked transient regime. Our measurements agree well with theory, in particular concerning the ratio of ...
Colliding-wind binary systems: diffusive shock acceleration and non-thermal emission
(Wiley Blackwell Publishing, Inc, 2020-06)
We present a model for the non-thermal emission from a colliding-wind binary. Relativistic protons and electrons are assumed to be accelerated through diffusive shock acceleration (DSA) at the global shocks bounding the ...
