In recent years, the utilization of 3D display systems became popular in many application areas. One of the most important issues in the utilization of these systems is to render the correct view to the observer based on his/her position. In this thesis, we propose and implement a single user view rendering system for autostereoscopic/stereoscopic displays. The system can easily be installed on a standard PC together with an autostereoscopic display or stereoscopic glasses (shutter, polarized, pulfrich, and anaglyph) with appropriate video card. Proposed system composes of three main blocks: view point detection, view point tracking and intermediate view reconstruction. Haar object detection method, which is based on boosted cascade of simple feature classifiers, is utilized as the view point detection method. After detection, feature points are found on the detected region and accordingly they are fed to the feature tracker. View point of the observer is calculated by using the tracked position of the observer on the image. Correct stereoscopic view is, then, rendered on the display. A 3D warping-based method is utilized in the system as the intermediate view reconstruction method. System is implemented on a computer with Pentium IV 3.0 GHz processor using E-D 3D shutter glasses and Creative NX Webcam.

<p>Vizz3D is a powerful 3D visualization system. The current version is neither perfect nor up-to-date. Furthermore, some important features are missing. In order to keep the tool valuable it needs to be maintained. I implemented a new feature allowing to save and load the view port in the graph to control the camera position. I also improved the CPU utilization and the navigation system to solve the limitations in Vizz3D and to improve the overall performance.</p>

O objetivo desta dissertação é descrever o comportamento do primitivo discursivo PONTO DE VISTA como proposto na teoria de espaços mentais (FAUCONNIER 1994, 1997) em duas narrativas em espanhol andino colombiano de Aldana. As narrativas foram extraídas de um corpus de entrevistas etnográficas colhido por Valentina Arango Villalón em 2011, em Aldana, na fronteira sul da Colômbia. Essas narrativas são fruto de uma entrevista feita por Arango Villalón e colegas com Manuel Erira, indígena pasto habitante da Reserva Indígena Pasto de Pastás em Aldana. Nelas, Erira explica a proveniência de alguns mitos e conta a história dos antepassados. Transcrevi as narrativas utilizando o software ELAN (desenvolvido pelo Max Planck Institute for Psycholinguistics) e utilizando unidades entoacionais (CHAFE, 1994) como unidade de segmentação do fluxo da fala. Uma vez transcritas as narrativas, apliquei o modelo da etnopoética de Hymes (1994), que resultou na organização das narrativas segundo a sucessão e repetição de elementos significativos da estruturação da ação. Finalmente, apliquei o modelo de espaços mentais à análise das duas narrativas seguindo as propostas de Fauconnier (1994, 1997), Cutrer (1994), Doiz-Bienzobas (1995), Tenuta (2006) e Tenuta e Lepesqueur (2014), dando especial atenção ao comportamento do primitivo discursivo PONTO DE VISTA. Discuti a possibilidade de compatibilizar a noção de PONTO DE VISTA como descrita no modelo de espaços mentais com o conceito de focalização no estudo de narrativas proposto por Genette (1980). Esta dissertação aponta para a possibilidade de que o primitivo PONTO DE VISTA seja uma categoria híbrida que descreve, em um primeiro momento o espaço mental a partir do qual outros espaços mentais são criados/acessados, e em um segundo momento o espaço a partir do qual se conceitualizam os eventos sendo elaborados no espaço FOCO. A dissertação mostra também como a proposta de Doiz-Bienzobas (1995), de que os espaços IMPERFECTIVOS têm um PONTO DE VISTA interno associado a um self-experienciador, se relaciona com a segunda característica do primitivo discursivo em questão, ou seja, ser o espaço a partir do qual se conceitualizam os eventos sendo elaborados no espaço FOCO. Finalmente, a dissertação mostra como o conceito de focalização em Genette (1980) não é equiparável ao primitivo discursivo PONTO DE VISTA no modelo de espaços mentais. / The objective of this dissertation was to describe the behavior of the VIEWPOINT discourse primitive, as proposed by mental spaces theory (FAUCONNIER 1994, 1997), in two narratives in Colombian Andean Spanish from Aldana. The narratives are part of a corpus of ethnographic interviews collected by Valentina Arango Villalón in 2011 in Aldana, on the southern border of Colombia. The narratives emerged in an interview conducted by Arango Villaón and colleagues with Manuel Erira, native to the Pasto Indigenous People of Pastás, in Aldana. In the narratives, Erira explains the origins of some myths and tells the story of his predecessors. I transcribed the narratives using ELAN (developed by the Max Planck Institute for Psycholinguistics) and the concept of intonation units (CHAFE, 1994) as units for the segmentation of the speech flow. I used Hymes´s(1994) model of ethnopoetics for the analysis of narrative structure, which resulted in an organization that responded to the succession and repetition of meaningful elements of action structure. I applied the model of mental spaces following Fauconnier (1994, 1997), Cutrer (1994), Doiz-Bienzobas (1995), Tenuta (2006) and Tenuta & Lepesqueur (2014), giving special attention to the discourse primitive VIEWPOINT. I discussed the possibility of matching the concept of VIEWPOINT as described in mental space theory and the concept of focalization as proposed by Genette (1980) in his study of narrative discourse. This dissertation shows the possibility of VIEPOINT being a hybrid category that describes first the mental space from which other spaces are created/accessed, and secondly the mental space from which the events described in FOCUS space are conceptualized. The dissertation also shows how Doiz- Bienzobas (1995) statement that IMPERFECTIVE spaces show an internal VIEWPOINT associated with an experiencer-self has to do with the second characteristic of VIEWPOINT stated above, namely that of VIEW POINT being the space from which events in FOCUS space are conceptualized. Finally, the dissertation shows how the notions of VIEWPOINT in mental space theory and focalization in Genettes (1980) are not equivalent.

This thesis is dealing with town side recreation. Natural environment, with forest as a dominating factor, is very important in this issue. Forests attract their visitors thanks to specific atmosphere and mostly they don{\crq}t need any additional equipment to fulfill their purpose within the frame of tourism. This doesn{\crq}t apply on smaller forest stands, so-called small-scale forest units, that attract just minimal attention by themselves. Small-scale forest units are offering relax potential, but this potential need to be developed. Through the use of convenient ground shaping, equipping and promotion of these small-scale forest units is possible to gain new recreation localities. This thesis is dealing with development of small-scale forest units nearby city Tábor.
