By identifying lip movements and characterizing their associations with speech sounds, the performance of speech recognition systems can be improved, particularly when operating in noisy environments. Various method have been studied by research group around the world to incorporate lip movements into speech recognition in recent years, however exactly how best to incorporate the additional visual information is still not known. This study aims to extend the knowledge of relationships between visual and speech information specifically using lip geometry information due to its robustness to head rotation and the fewer number of features required to represent movement. A new method has been developed to extract lip geometry information, to perform classification and to integrate visual and speech modalities. This thesis makes several contributions. First, this work presents a new method to extract lip geometry features using the combination of a skin colour filter, a border following algorithm and a convex hull approach. The proposed method was found to improve lip shape extraction performance compared to existing approaches. Lip geometry features including height, width, ratio, area, perimeter and various combinations of these features were evaluated to determine which performs best when representing speech in the visual domain. Second, a novel template matching technique able to adapt dynamic differences in the way words are uttered by speakers has been developed, which determines the best fit of an unseen feature signal to those stored in a database template. Third, following on evaluation of integration strategies, a novel method has been developed based on alternative decision fusion strategy, in which the outcome from the visual and speech modality is chosen by measuring the quality of audio based on kurtosis and skewness analysis and driven by white noise confusion. Finally, the performance of the new methods introduced in this work are evaluated using the CUAVE and LUNA-V data corpora under a range of different signal to noise ratio conditions using the NOISEX-92 dataset.

The problem of this study is the relationship of perception and a selected communication model to filmstrip design.

Cinema copyright - Abstract Cinema copyright - a list of all issues concerning copyright protection, which might be dealt with in a cinema building. The thesis "Cinema Copyright" is focused on the problems of copyright protection of audio-visual work, live broadcast and other activities which most often take place in a grand hall of a cinema. The author holds a position of a director of a one-hall city digital cinema. Therefore, it is not the only goal of this thesis to take a positive view of the issues in the legal sense of the word, but also to confront the legal regulation with the common practice in the field in the way I and my colleagues experience it on a daily basis. As a result I propose some changes regarding the matters in question. Except for the first chapter, the whole thesis deals with the legal relations between a cinema operator and a distributor. The text is related to the actual state of legal affairs by February 4, 2013. The first chapter is concerned in detail with the current terminology of audio-visual work and the people within the scheme of its production. In this part a detail analysis of the legal framework of the production of audio-visual work and of the legal relations among the people within the production scheme is given. The second chapter presents the reasons for...

Objetiva-se, assim, imputar a necessidade de que o documento audiovisual seja reconhecido como documento de arquivo e seja inserido nos procedimentos de gestão documental. Para tanto, procede-se a abordagem dos princípios arquivísticos que pauta a gestão de documentos, bem como das características e do percurso histórico dos documentos audiovisuais em arquivos no Brasil, partindo inicialmente da pesquisa bibliográfica para a delimitação do tema de estudo. Nesse sentido, analisam-se tais questões no âmbito nacional, tomando como base os órgãos oficiais de formulação das políticas arquivísticas, assim como dos eventos e publicações promovidos por esses órgãos e associações profissionais da Arquivologia. Tais procedimentos têm como propósito embasar e adquirir informações para o desenvolvimento dessa pesquisa e propor novos olhares sobre esses documentos e suas especificidades, a partir dessa análise retroativa da área dos arquivos no Brasil.

It is therefore intended to imply the need for the audiovisual record to be recognized as an archival record and to be included in record management procedures. Therefore, the archival principles that guide the records managment, as well as the characteristics and the historical path of audiovisual records in archives in Brazil, are based on the principles of archival principles, starting from the bibliographic research for the delimitation of the topic of study. In this sense, these questions are analyzed at the national level, based on the official bodies for the formulation of archival policies, as well as the events and publications promoted by these professional associations and bodies of the Records Managment. These procedures have as purpose to base and acquire information for the development of this research and to propose new approches on these records and their specificities, from this retroactive analysis of the area of archives in Brazil. In this way, it is observed that the reflection... (Complete abstract click electronic access below) / Doutor

Esta pesquisa propõe uma análise do processo de apropriação de ferramentas audiovisuais entre os Manoki, povo indígena de tronco isolado que vive ao noroeste de Mato Grosso, e suas correlações com os discursos nativos sobre a história. A partir de uma etnografia mediada pelo vídeo utilizado pelos indígenas de forma proeminentemente prospectiva em estratégias de registro e autorrepresentação , chega-se a diversos temas próprios da etnologia indígena, como relações intergeracionais, concepções sobre tempo, ritual e escatologia. Ao conjugar as abordagens antropológicas sobre audiovisual e povos ameríndios, a análise pretende levar em consideração a perspectiva nativa a propósito das transformações em seu mundo e o papel que o registro audiovisual pode ter para os Manoki. / This research proposes an analysis of the appropriation process of audio-visual tools among the Manoki, indigenous people who live in northwest of Mato Grosso, and their correlations with native discourses about history. Through an ethnography mediated by video used by indigenous people in a prominently prospectively way in strategies for registration and selfrepresentation we arrive at several ethnological themes such as intergenerational relationships, conceptions of time, ritual and eschatology. By combining anthropological approaches in audio-visual and Amerindian peoples, the analysis aims to take into account the native perspective on the subject of changes in their world and the role that audio-visual records may have to Manoki people.
