Método para compressão de imagens digitais fundamentado em procedimentos de Huffman e Wavelets.
(Universidade Federal de São Carlos, 2005-08-05)
The amount of transmitted, stored and accessed information by
computers have been growing exponentially on the last decades. Two factors have
contributed to this effect, one is the appearing of the multimedia systems with ...
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 ...
Reconstrução tomográfica de imagens utilizando técnicas POCS seqüenciais e paralelas.
(Universidade Federal de São Carlos, 2001-08-31)
In this dissertation four algorithms are presented for the tomographic reconstruction of images using methods denominated POCS - Projections onto Convex Sets, which are the ART - Algebraic Reconstruction Technique, the ...
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 ...
Arquitetura de redes neurais para o reconhecimento facial baseado no neocognitron.
(Universidade Federal de São Carlos, 2001-09-27)
In this dissertation it is presented a face recognition system based in the neocognitron
(NEOPC). This system is divided into three major stages: (a) pré-processing: which normalizes the facial samples utilized in the ...
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 ...
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 ...
