13. Fusão biométrica com lógica nebulosa / Multimodal biometric fusion with fuzzy logic
Neste trabalho, apresentamos um novo método para fazer a fusão de dois sistemas biométricos unimodais. O objetivo é gerar um sistema biométrico multimodal que apresente menores taxas de erro, maior robustez e maior segurança. O método proposto pode ser usada para integrar qualquer tipo de modalidade biométrica. Desta forma, fazemos uma descrição ge

14. Técnicas de processamento de imagens para localização e reconhecimento de faces / Image processing techniques for faces location and recognition
Biometry is the science of measuring and analyzing biomedical data. Many works in this field have explored the characteristics of human beings, such as digital fingerprints, iris, and face to develop biometric systems, employed in various aplications (security monitoring, ubiquitous computation, robotic). Face identification and recognition are very apealing

15. Avaliação de uma metodologia para otimização de volume de toras comerciais de Eucalyptus sp. em função da qualidade do fuste / Evaluation of a methodology for volume optimization of Eucalyptus sp. merchantable logs as a function of stem quality
This work had as general objective the evaluation of a methodology for estimate of the wood volume in the forest inventory, considering the profile of quality of the stem of the trees. A stand was used with area of 4,31 ha planted with Eucalyptus sp. with 16 year-old, originated from seminific propagation. The initial spacing used in the planting was 3 x 3 m

16. Investigação biométrica em imagens digitais para detecção de faces humanas através da proporção divina / Biometric investigation in digital images for the detection of human faces by divine proportion
The increase of recognition systems in the contemporary world has demanded robust and agile detection processes. From teleconference systems to security and monitoring mechanisms, the detection and recognition of people have became constantly used and applied. In attempt to search for alternative ways to solve both detection and recognition problems, this wo

17. MEAT PRODUCTION WITH POLWARTH AND POLWARTH X BORDER LEICESTER CROSSBRED LAMBS ON SUPPLEMENTED NATURAL PASTURE AND CULTIVED PASTURE WITH OR WITHOUT SUPPLEMENTATION / PRODUÇÃO DE CARNE DE CORDEIROS DA RAÇA IDEAL E CRUZAS IDEAL X BORDER LEICESTER TERMINADOS EM CAMPO NATURAL SUPLEMENTADO E PASTAGEM CULTIVADA COM OU SEM SUPLEMENTAÇÃO
The objectives of this work were to verify the feeding systems and genotype effect on Polwarth and Polwarth x Border Leicester crossbred lambs performance and carcass characteristics. The experiment was carried out in two times: on the first, before slaughter, were estimated the pasture and animal characteristics; and the second, after slaughter, were estima

18. Classificação e recuperação de imagens por cor utilizando técnicas de inteligência artificial
Image retrieval and classification are today the subject of extensive research. This topic poses both theoretical and practical challenges as researchers attempt to give machines such as computers and robots the ability to see. Image retrieval and classification are part of a wider field known as Computer Vision, which encompasses several practical applicati

19. Sistemas de identificação pessoal utilizando tecnicas de reconhecimento e verificação facial automaticas
This thesis dissertation shows the development of biometrics systems based in face recognition technics. These biometric systems are able to recognize and identify people by extracting information from their facial images. Face recognition systems must have a model to encode and represent facial image information for recognition purposes. We choose the eigen

22. Iris recognition in the presence of ocular disease
Iris recognition systems are among the most accurate of all biometric technologies with immense potential for use in worldwide security applications. This study examined the effect of eye pathology on iris recognition and in particular whether eye disease could cause iris recognition systems to fail. The experiment involved a prospective cohort of 54 patient
