Avaliação das técnicas de segmentação, modelagem e classificação para o reconhecimento automático de gestos e proposta de uma solução para classificar gestos da libras em tempo real
(Universidade Federal de São Carlos, 2013-10-22)
Multimodal interfaces are becoming popular and trying to enhance user experience through the use of natural forms of interaction. Among these forms we have speech and gestures inputs. Speech recognition is already a common ...
Filtragem MAP 2-D de imagens CT ruidosas
(Universidade Federal de São Carlos, 2011-08-26)
Computed tomography has been widely used for medical diagnosis, since it allows viewing of internal parts of a body without overlapping structures. However, recent studies indicate a certain risk of cancer to the patients ...
Processamento digital de imagens para inferência de risco de doença fúngica da bananicultura
(Universidade Federal de São Carlos, 2012-06-11)
The digital image processing has been used to solve a significant number of problems in the agricultural sector, especially with the evolution of remote sensing systems. This work presents a computational model based on ...
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 ...
Istar: um esquema estrela otimizado para Image Data Warehouses baseado em similaridade
(Universidade Federal de São Carlos, 2011-08-26)
A data warehousing environment supports the decision-making process through the investigation and analysis of data in an organized and agile way. However, the current
data warehousing technologies do not allow that the ...
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, ...
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 ...
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. ...
