13. Seleção seqüencial de descritores por análise da semântica para recuperação de imagens baseada no conteúdo
Na recuperação de imagens basada no conteúdo - CBIR, cada imagem é representada pelas suas características de baixo nível como são: cor, forma, textura, etc. A representação da semântica das imagens por características de baixo nível é um problema em aberto. Novos algoritmos para a extração de características assim como novos métodos de inde

14. Reducing the semantic gap content-based image retrieval with similarity queries / Adequando consultas por similaridade para reduzir a descontinuidade semântica na recuperação de imagens por conteúdo
The increasing number of images captured in digital media fostered the developmet of new methods for the recovery of these images. Dissimilarity is a criteria that can be used for image retrieval, where the results are images that are similar to a given reference. The queries are based on feature vectors automatically extracted from the images and on distanc

15. Caracterização de imagens utilizando redes neurais artificiais
Image representation in Content Based Image Retrieval systems is a fundamental task. The results obtained by these systems strongly depend on the choice of features selected to represent an image. Works in the literature show that intelligent techniques are used to minimize the semantic gap between the limited power of machine interpretation and human subjec

16. Images of the baroque memory of Ouro Preto: the baroque space as educator of imaginary from Ouro Preto / Imagens da memória barroca de Ouro Preto: o espaço barroco como educador do imaginário ouro-pretano
The present research was, theoretically and methodologically, based on an interpretative and translator analysis of the meaning of verbal and non-verbal images and symbols (semanticsymbolic hermeneutics). The purpose of it was to investigate the influence and the coimplication of the iconographic and architectural images from Ouro Pretos baroques churches on

17. Recuperação de imagens por conteúdo: uma abordagem multidimensional de modelagem de similaridade e realimentação de relevância
This work presents a multi-dimensional similarity modeling strategy and relevance feedback technique for minimizing the semantic gap intrinsic problem of CBIR systems by allowing users to customize their queries according to their requirements and preferences. We propose a composite strategy using a multi-dimensional, vectorial, spatially clustered, and rele

18. A methodology for development augmented reality applications using mobile phones and sensors devices. / Uma metodologia para o desenvolvimento de aplicações de realidade aumentada em telefones celulares utilizando dispositivos sensores.
Handheld Augmented Reality or Handheld AR is the implementation of Augmented Reality (AR) systems into handheld devices. Handheld AR applications use the handheld devices camera to recognize markers (inserted into the environment). This process enables data entry into AR system. The response generated for these applications are presented as virtual images (3

19. Suporte a sistemas de auxílio ao diagnóstico e de recuperação de imagens por conteúdo usando mineração de regras de associação / Supporting Computer-Aided Diagnosis and Content-Based Image Retrieval Systems through Association Rule Mining
In this work we take advantage of association rule mining to support two types of medical systems: the Content-based Image Retrieval (CBIR) and the Computer-Aided Diagnosis (CAD) systems. For content-based retrieval, association rules are employed to reduce the dimensionality of the feature vectors that represent the images and to diminish the semantic gap t

20. The expression of evidentiality in political speech: an analysis of political speech of the State Legislature of CearÃ. / A expressÃo da evidencialidade no discurso polÃtico: uma anÃlise da oratÃria polÃtica da AssemblÃia Legislativa do CearÃ
The present research aims at investigating the expression of evidentiality and its relation to the degrees of public speakerâs commitment with the contents uttered in political speech argumentationâs construction. Thirty speeches, subdivided in two thematic groups: 1) the arrival of a petrol refinery in the state of CearÃ; and 2) the transposition of SÃo

21. Uma educação da alma: literatura e imagem arquetípica / An education of the soul: Literature and archetypal image
This present study tries to register images of a life history articulated by images of the literature - these latter ones appropriated by the subjectivity towards an education of the soul. Being so, I launch myself, starting from my experiences as a reader, into a theoretical-analytical path based on an anthropo-literary view in which literature is understoo

22. Proposal of a perception color histogram as characteristic for content-based image retrieval / Proposta de um histograma perceptual de cores como característica para recuperação de imagens baseada em conteúdo
This work aims at establishing a digital image classification methodology based on perceptual colors, by generating a feature vector that allows retrieving images from a database by their content. In related works the methodologies of grouping the diverse possible colors of an image do not allow associate digitized colors and those colors perceived by human

23. Relevance Feedback to content-based image retrieval to minimize semantic gap / "Realimentação de relevância para recuperação por conteúdo de imagens médicas visando diminuir a descontinuidade semântica"
O objetivo deste projeto de Mestrado foi o estudo, a análise e o desenvolvimento de técnicas de Realimentação de Relevância (RR) para melhorar a respostas de consultas por similaridade que empregam técnicas de recuperação de imagens por conteúdo (do inglês content-based image retrieval - CBIR). A motivação para o desenvolvimento deste projeto vei

24. Reflexões sobre a materialidade numa abordagem imagético-apresentativa : narrativa de um percurso teórico e prático à luz da psicologia analítica / Reflections on materiality in an imagetical-presentative approach : narrative of a theoretical and practical path in the light of the analytical psychology
This dissertation relates the path followed by the researcher around the notion of materiality in order to discuss and illustrate an imagetical-presentative approach in the light of the Analytical Psychology. This notion is compared to correlative terms used by authors that also worried about it, like Gaston Bachelard, Alvaro Gouvêa and others closer to
