Redução de dimensionalidade usando agrupamento e discretização ponderada para a recuperação de imagens por conteúdo
(Universidade Federal de São Carlos, 2012-11-19)
This work proposes two new techniques of feature vector pre-processing to improve CBIR and image classification systems: a method of feature transformation based on the k-means clustering approach (Feature Transformation ...
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 ...
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 ...
