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 ...
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 ...
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 ...
Análise de estruturas de rede neocognitron para aplicação no reconhecimento facial
(Universidade Federal de São Carlos, 2008-08-13)
The present work consists in the use of the combination of neocognitron networks for the face recognition tasks integrating a system of face recognition, categorized as holistic method, by the fact of to approach all the ...
Restauração de imagens em vibro-acustografia
(Universidade Federal de São Carlos, 2008-03-10)
Vibro-acoustography is an imaging modality that produces a map of the mechanical response of an object to a localized dynamic radiation force produced by an ultrasound field. This technique has been studied and used in ...
Métodos para um sistema de animação facial baseado em aquisição estereoscópica.
(Universidade Federal de São Carlos, 2006-05-20)
Facial animation has been widely used in many areas of applications and entertainment,
presenting high levels of details and technology. However, its implementation still demands
lots of hard work from the producer ...
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 ...
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 ...
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 ...
