1. Esqueletos euclidianos discretos em resolução aumentada / Discrete euclidean skeletons in increased resolution
The extraction of Euclidean skeletons is a subject of great importance in the domain of image processing and it has been discussed by the scientific community since more than 20 years.Today it is a consensus that Euclidean skeletons should present the following characteristics: thin, centered, homotopic and reversible, i.e., suficient for the reconstruction

2. Método de reconhecimento pessoal através da íris usando funções geoestatísticas / Method of personal recognition through iris texture using geostatistics functions
Biometrics identification methods are gaining applications each day and this has motivated a lot of research in this area. This work presents a proposal for a method to identify people through iris texture analysis using geostatistics functions and their combination. To achieve this work objective, it is considered the following phases: automatic localizatio

3. "Parallel implementation of the exact Euclidean distance transform" / "Implementação paralela da transformada de distância euclidiana exata"
The Euclidean distance transform is the operation that converts a binary image made of object and background pixels into another image, the Euclidean distance map, where each pixel has a value corresponding to the Euclidean distance from this pixel to the background. The Euclidean distance transform has important uses in computer vision, image analysis and r

4. Utilization of spectroscopy in the infrared region (FTIR) and chemometry in the identification of adulterated toasted and ground coffee. / UtilizaÃÃo da espectroscopia na regiÃo do infravermelho (FTIR) e quimiometria na identificaÃÃo do cafà torrado e moÃdo adulterado.
In this work the potentialities of the chemometric techniques and the eases in the obtaining of spectra presented by the spectroscopy techniques in the infra-red region with Fourier transform (FTIR) through the attenuated total reflectance (ATR), drift reflectance (DRIFT) and transmittance, aiming at the identification of barley (substance used as an adulter

5. Projeto de operadores de processamento e analise de imagens baseados na transformada imagem-floresta
t: In image processing and analysis, many problems can be thought of as an optimal image partition problem based on seed pixels, where each seed defines an influence zone composed by its "closest" pixels. The image foresting transform (1FT) is a unified and efficient approach to solve these problems, by reducing them into a shortest-path forest problem in
