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 ...
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 ...
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. ...
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 ...
