Three-dimensional reconstruction of non-homogeneous dielectric objects by the coupled-dipole method
(Sociedade Brasileira de Física, 2007)
In this paper we present an inversion procedure for electromagnetic scattering, based on the coupled-dipole method (CDM) combined with an inversion algorithm making use of the singular value decomposition procedure associated ...
Otimização inteligente da decomposição de elemento estruturante em morfologia matemática binária
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2014-03-14)
When working with binary images, mathematical morphology provides powerful tools for analyzing them. Along with genetic algorithms, it allows various computational tasks that are performed autonomously. In recent decades, ...
Restauração de imagens digitais com texturas utilizando técnicas de decomposição e equações diferenciais parciais

A Decomposition and Noise Removal Method Combining Diffusion Equation and Wave Atoms for Textured Images
(Hindawi Publishing Corporation, 2010-01-01)
We propose a new method that is aimed at denoising images having textures. The method combines a balanced nonlinear partial differential equation driven by optimal parameters, mathematical morphology operators, weighting ...

On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)
Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ...

Chemical species separation with simultaneous estimation of field map and T-2* using a k-space formulation
(WILEY-BLACKWELL, 2012)
Chemical species separation techniques in image space are prone to incorporate several distortions. Some of these are signal accentuation in borders and geometrical warping from field inhomogeneity. These errors come from ...
Image-quality optimization for dual energy computed tomography (DECT) three-material decomposition
(Biomédica, Mecatrónica y MecánicaEscuela de Ingeniería de Antioquia EIAUniversidad CES, 2014-04-23)
Dual energy computed tomography, which consists of the acquisition of two images of a given region of interest
using two different x-ray energies, has been used to decompose images. For example, it has been proposed to ...
