Um modelo de visão computacional para identificação do estágio de maturação e injúrias no pós-colheita de bananas (Musa sapientum)
(Universidade Federal de São Carlos, 2009-09-28)
This dissertation presents the development of a computer vision system for bananas (Musa sapientum) analysis in post-harvest stage based on digital image processing techniques. The development used considerations about ...
Combinação de múltiplos classificadores para identificação de materiais em imagens ruidosas
(Universidade Federal de São Carlos, 2004-05-28)
Material identification in images has been explored in multiple areas and very interesting
applications are arising in this field. This work uses noisy multispectral images from a
computerized tomograph scanner acquired ...
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 ...
Uso do algoritmo ICM adaptativo a descontinuidades para o aumento da resolução de imagens digitais por técnicas de reconstrução por super resolução
(Universidade Federal de São Carlos, 2007-05-22)
Super resolution image reconstruction consists in using a set of low resolution images from the same scene to generate a high resolution
estimate of the original scene. For that purpose, all the observed low resolution ...
Restauração de imagens de microscopia confocal utilizando técnicas POCS.
(Universidade Federal de São Carlos, 2005-09-23)
Computer Optical Sectioning Microscopy (COSM) is widely used in morphological studies of cellular structures. COSM appears as a great challenge to digital image processing, because the large size of the three-dimensional ...
Projeto e construção de um scanner antropométrico baseado no método de triangulação a laser.
(Universidade Federal de São Carlos, 2005-08-30)
Three-dimensional (3D) surface anthropometry enables us to extend the study to 3D geometry and morphology of human body. The purpose of this study is to build a whole 3D body scanner. Using lasers and cameras mounted on a ...
Desenvolvimento de descritores de imagens para reconhecimento de padrões de plantas invasoras (folhas largas e folhas estreitas)
(Universidade Federal de São Carlos, 2009-06-05)
In Brazil, the development of tools for weeds recognition, capable of aiding risk detection and decision making on the fieldwork is still embryonic. This master s thesis presents the development of a pattern recognition ...
Análise de imagens tomográficas da Ciência do Solo em ambiente de realidade virtual
(Universidade Federal de São Carlos, 2008-08-28)
This work presents a Virtual Reality environment dedicated to the analysis of tomographic images of Soil Science. Its architecture uses models proceeding from a volumetric (3-D) reconstruction algorithm, summed with several ...
Restauração das imagens do satélite CBERS-1 utilizando POCS.
(Universidade Federal de São Carlos, 2005-02-18)
The number of applications in remote sensing has widely increased in the last years. The reason for this is mainly the high quality of imaging systems onboard. Among this new generation of satellites, the CBERS-1 (China-Brazil ...
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 ...
