1. Feature Level Two -Dimensional Arrays Based Fusion in the Personal Authentication system using Physiological Biometric traits
ABSTRACT The fingerprint, knuckle print and the retina are used to authenticate a person accurately because of the permanence in the features. These three biometric traits are fused for better security. The fingerprint and knuckle print images are pre-processed by morphological techniques and the features are extracted from the normalized image using gabor f

2. Improvements in fingerprint recognition based on the FingerCode method / Melhorias no reconhecimento de impressões digitais baseado no metodo FingerCode
Neste trabalho são apresentadas melhorias na robustez do método FingerCode para reconhecimento de impressões digitais. No FingerCode a textura dos componentes orientados das impressões digitais são extraídas por um banco direcional de filtros Gabor. Posteriormente, os componentes orientados são setorizados e para cada setor é computado um valor. Este

3. Projeto de novos sistemas-wavelet com aplicaÃÃes na anÃlise de sinais do sistema elÃtrico / Design of new wavelet systems with applications in power system signal analysis
The wavelet transform equipped with the multiresolution analysis has been offered as an efficient tool in the investigation of non stationary signals derived from a plenty of areas. The development of new âbasisâ so as to implement such techniques has the aim of enlarging the span of suitable choices for a particular purpose. This thesis introduces new fam
