Sistema para tomada de decisão baseado na geração de imagens estereoscópicas e reconhecimento de padrões circulares.
(Universidade Federal de São Carlos, 2003-08-20)
In this work, it is presented a system for decision-making based on stereoscopic image generation and recognition of circular patterns.
For stereoscopic imaging are used two low cost Web cam in canonical configuration and ...
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 ...
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. ...
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 ...
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 ...
Filtragem de ruído em imagens tomográficas com baixa taxa de contagem utilizando uma abordagem bayesiana contextual
(Universidade Federal de São Carlos, 2013-03-22)
Computed Tomography (CT) images, in many cases, need to be acquired with low photon counting due to low exposure time to the rays of the CT scanner to reduce the radiation doses to the maximum possible (in Medicine, the ...
Método para compressão de imagens digitais fundamentado em procedimentos de Huffman e Wavelets.
(Universidade Federal de São Carlos, 2005-08-05)
The amount of transmitted, stored and accessed information by
computers have been growing exponentially on the last decades. Two factors have
contributed to this effect, one is the appearing of the multimedia systems with ...
Análise quantitativa de culturas de neurônios em matrizes de microeletrodos por meio do processamento de imagens de microscopia confocal de fluorescência
(Universidade Federal de São Carlos, 2015-03-09)
Microelectrode arrays (MEA) are devices that allow chemical and electrical stimulation and recording of the extracellular electrical activity from entire neuronal cultures over long periods of time, such as several weeks. ...
Otimização inteligente da decomposição de elemento estruturante em morfologia matemática binária
(Universidade Federal de São Carlos, 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, ...
