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 ...
Desenvolvimento de um sistema de aquisição de informações volumétricas usando métodos de triangulação a laser e campo de visão variável.
(Universidade Federal de São Carlos, 2004-08-31)
The most efficient 3D acquisition systems use the principle of laser
triangulation or the principle of time of flight TOF. In the systems based on
triangulation, the range and the depth variation are very limited, but ...
Método fundamentado em processamento digital de imagens para contagem automática de unidades formadoras de colônias.
(Universidade Federal de São Carlos, 2006-08-17)
This work presents a computer aided system for automated counting of colony formation units
in Petri dishes. The method implemented uses digital image processing, and among them Hough
transform for circular objects and ...
Super resolução baseada em métodos iterativos de restauração
(Universidade Federal de São Carlos, 2013-06-24)
The resolution enhancement of an image is always desirable, independently of its objective, but mainly if the image has the purpose of visual analysis. The hardware development for increasing the image resolution still has ...
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 ...
Algoritmo genético embarcado aplicado à indução de operadores morfológicos
(Universidade Federal de São Carlos, 2016-03-07)
The use of genetic algorithms, evolutionary strategies and genetic programming has been
notoriously addressed in the areas of image processing and computer vision and has contributed with diverse results. However, this ...
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 ...
Algoritmos para a redução de ruído Poisson e estimativa de parâmetros utilizando distâncias estocásticas
(Universidade Federal de São Carlos, 2018-06-14)
Noise is present in all applications of digital imaging. Due to its stochastic nature, it is impossible to determine exact procedures to completely remove noise from the image. Thus, the target signal may be affected during ...
Métodos para reconhecimento de íris em ambiente não cooperativo
(Universidade Federal de São Carlos, 2012-06-14)
The identification of humans by their iris structure has been explored since 1993, when the first algorithm was made available by John Daugman. Since then, iris recognition systems are widely used for access control of ...
