Algoritmo genético embarcado aplicado à indução de operadores morfológicos
(Universidade Federal de São Carlos, 2016-03-07)
The use of genetic algorithms, evolutionary strategies and genetic programming has been
notoriously addressed in the areas of image processing and computer vision and has contributed with diverse results. However, this ...
Filtragem de ruído speckle em imagens de radar de abertura sintética por filtros de média não local com transformação homomórfica e distâncias estocásticas
(Universidade Federal de São Carlos, 2014-01-23)
The development of new methods and noisy images filtering techniques still attract researchers, which seek to reduce the noise with the minimal loss of details, edges, resolution and removal of fine structures of the image. ...
Reconhecimento de gestos da Língua Brasileira de Sinais através de máquinas de vetores de suporte e campos aleatórios condicionais ocultos
(Universidade Federal de São Carlos, 2013-05-24)
This work investigates the use of Support Vector Machines and Hidden Conditional Random Fields in the recognition of signs from the Brazilian Sign Language (Língua Brasileira de Sinais, Libras). Employing basic concepts ...
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 ...
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 ...
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 ...
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 ...
Método de processamento digital de imagens para inferência da qualidade de materiais preparados com fibras vegetais
(Universidade Federal de São Carlos, 2013-08-02)
This Dissertation presents a method development based on image processing techniques, which enables the verification and quality analysis of organic fibers mixture in thermoplastic starch (TPS). In order to do this analysis, ...
Análise da evolução da dinâmica de uma cultura de neurônios dissociados em matriz de microeletrodos usando Coerência Parcial Direcionada e Redes Complexas
(Universidade Federal de São Carlos, 2012-08-18)
Multi-Electrode Array, MEA, was developed more than thirty years ago. This planar device of multiple microelectrodes has been used to detect local electric potential variations created by the ion movement through the protein ...
