Simulador de arquitetura para processamento de imagens usando programação genética cartesiana
(Universidade Federal de São Carlos, 2013-12-20)
The tools offered by the area of Mathematical Morphology are very effective when applied to the analysis of binary images, which it is of great importance in areas such as: robotic vision, visual inspection, among others. ...
Abordagens não-locais para filtragem de ruído Poisson
(Universidade Federal de São Carlos, 2014-05-23)
A common problem to applications such as positron emission tomography, low-exposure X-ray imaging, fluorescence microscopy, optical and infrared astronomy, and others, is the degradation of the original signal by Poisson ...
Novas propostas em filtragem de projeções tomográficas sob ruído Poisson
(Universidade Federal de São Carlos, 2010-05-24)
In this dissertation we present techniques for filtering of tomographic projections with Poisson noise. For the filtering of the tomogram projections we use variations of three filtering techniques: Bayesian estimation, ...
Reconstrução 3D de imagens tomográficas de raios-x de arcos coronais em ambiente paralelo.
(Universidade Federal de São Carlos, 2003-05-30)
Space researches have been carried with the objective to forecast solar explosions, through images obtained by satellites equipped with X-ray telescopes. The highresolution solar images allow the study of the spatio-temporal ...
Filtragem de sinograma tomográfico afetado por ruído Poisson utilizando wavelets anisotrópicas
(Universidade Federal de São Carlos, 2017-02-07)
The diagnostic imaging by computed tomography has become popular in recent decades. As the image acquisition method is effected by exposing the human body to X-ray dose (ionizing radiation), the frequent realization of ...
