Semi-global techniques in image matching and change detection with applications to civil and environmental engineering.

This work of thesis wants to present a dissertation of the wide range of modern dense matching algorithms, which are spreading in different application and research fields, with a particular attention to the innovative “Semi-Global” matching techniques. The choice of develop a semi-global numerical code was justified by the need of getting insight on the variables and strategies that affect the algorithm performances with the primary objective of maximizing the method accuracy and efficiency, and the results level of completeness. The dissertation will consist in the metrological characterization of the proprietary implementation of the semi-global matching algorithm, evaluating the influence of several matching variables and functions implemented in the process and comparing the accuracy and completeness of different results (digital surface models, disparity maps and 2D displacement fields) obtained using our code and other commercial and open-source matching programs in a wide variety of application fields.

TV DIGITAL INTERATIVA NO BRASIL: ESTUDO DOS APLICATIVOS INTERATIVOS STICKERCENTER E DO TELEJORNAL MGTV

Com o avanço da tecnologia e chegada da TV digital no Brasil, estudos apontam que a televisão aberta começa um novo estágio desde seu surgimento. Esta mídia disponibiliza ferramentas que permitem aos emissores de conteúdo uma dimensão interativa ainda não experimentada, sobretudo nos processos de comunicação massivos indicando que é possível novos caminhos de investimento na produção de conteúdo por parte das emissoras de TV. Com esta realidade de fundo, experiências começam a ser testadas no âmbito da televisão, como o StickerCenter, um software - desenvolvido pela TOTVS - que reúne elementos da internet na TV possibilitando ao receptor maior interação com o conteúdo televisivo, outra experiência é a realizada pela Rede Integração, afiliada à Rede Globo em Minas Gerais, com o software desenvolvido pela HXD Interactive Television, que testa um modelo brasileiro de interatividade no telejornal. Este trabalho mostra como estas duas empresas estão desenvolvendo aplicativos interativos para a TV utilizando o Middleware Ginga e os motivos pelos quais sua popularização não aconteceu. O StickerCenter não se popularizou e indica que o motivo seja erro de estratégia da empresa em desenvolver um produto que une broadband e broadcast TV sem atrativos ao consumidor, já o aplicativo interativo da Rede Integração não foi colocado no ar e apresenta inúmeros fatores que demonstram que não explorará a interatividade pela ausência de canal de retorno. Este estudo investigou o impacto da interatividade no mercado da radiodifusão e como a convergência tecnológica aponta para a construção de uma nova mídia baseada em displays interativos capazes de oferecer aos consumidores uma nova forma de recepção de conteúdo.

Digital video transmission over wireless networks

The advent of the Integrated Services Digital Network (ISDN) led to the standardisation of the first video codecs for interpersonal video communications, followed closely by the development of standards for the compression, storage and distribution of digital video in the PC environment, mainly targeted at CD-ROM storage. At the same time the second-generation digital wireless networks, and the third-generation networks being developed, have enough bandwidth to support digital video services. The radio propagation medium is a difficult environment in which to deploy low bit error rate, real time services such as video. The video coding standards designed for ISDN and storage applications, were targeted at low bit error rate levels, orders of magnitude lower than the typical bit error rates experienced on wireless networks. This thesis is concerned with the transmission of digital, compressed video over wireless networks. It investigates the behaviour of motion compensated, hybrid interframe DPCM/DCT video coding algorithms, which form the basis of current coding algorithms, in the presence of high bit error rates commonly found on digital wireless networks. A group of video codecs, based on the ITU-T H.261 standard, are developed which are robust to the burst errors experienced on radio channels. The radio link is simulated at low level, to generate typical error files that closely model real world situations, in a Rayleigh fading environment perturbed by co-channel interference, and on frequency selective channels which introduce inter symbol interference. Typical anti-multipath techniques, such as antenna diversity, are deployed to mitigate the effects of the channel. Link layer error control techniques are also investigated.
