COMPONENTES INTERATIVOS PARA APRESENTAÇÕES EM MPEG-4

O padrão MPEG-4 tem se difundido largamente entre os diversos dispositivos capazes de apresentar conteúdo digital multimídia. Apesar do maior uso do padrão MPEG-4 ser na apresentação de vídeos, este padrão permite a inserção de objetos complexos a serem apresentados em conjunto com o vídeo, incluindo software executável. O presente artigo visa apresentar como um software executável interage com o sistema MPEG-4 e quais ferramentas (player, encoder e decoder) são utilizadas para gerar e executar este conteúdo multimídia

Shadows : uma nova forma de representar documentos

Orientador: Claudia Maria Bauzer MedeirosDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: Ferramentas de produção de documentos estão cada vez mais acessíveis e sofisticadas, resultando em um crescimento exponencial de documentos cada vez mais complexos, distribuídos e heterogêneos. Isto dificulta os processos de troca, anotação e recuperação de documentos. Enquanto mecanismos de recuperação da informação concentram-se apenas no processamento de características textuais (análise de corpus), estratégias de anotação de documentos procuram concentrar-se em formatos específicos ou exigem que o documento a ser anotado siga padrões de interoperabilidade - definidos por esquemas. Este trabalho apresenta o nosso esforço para lidar com estes problemas, propondo uma solução mais flexível para estes e outros processos. Ao invés de tentar modificar ou converter um documento, ou concentrar-se apenas nas características textuais deste, a estratégia descrita nesta dissertação propõe a elaboração de um descritor intermediário - denominado shadow - que representa e sumariza aspectos e elementos da estrutura e do conteúdo de um documento que sejam relevantes a um dado domínio. Shadows não se restringem à descrição de características textuais de um documento, preservando, por exemplo, a hierarquia entre os elementos e descrevendo outros tipos de artefatos, como artefatos multimídia. Além disto, Shadows podem ser anotados e armazenados em bancos de dados, permitindo consultas sobre a estrutura e conteúdo de documentos, independentemente de formatosAbstract: Document production tools are present everywhere, resulting in an exponential growth of increasingly complex, distributed and heterogeneous documents. This hampers document exchange, as well as their annotation and retrieval. While information retrieval mechanisms concentrate on textual features (corpus analysis), annotation approaches either target specific formats or require that a document follows interoperable standards - defined via schemas. This work presents our effort to handle these problems, providing a more flexible solution. Rather than trying to modify or convert the document itself, or to target only textual characteristics, the strategy described in this work is based on an intermediate descriptor - the document shadow. A shadow represents domain-relevant aspects and elements of both structure and content of a given document. Shadows are not restricted to the description of textual features, but also concern other elements, such as multimedia artifacts. Furthermore, shadows can be stored in a database, thereby supporting queries on document structure and content, regardless document formatsMestradoCiência da ComputaçãoMestre em Ciência da Computaçã

A Component And Query Approach For Scientific Data Exploration Applications

The immense increase of scientific databases, combined with the spread of open standards for service interfaces, has resulted in unprecedented opportunities of data exploration and exploitation for scientists. From a client point of view, scientists often perform data combination and analysis, based on interactive incremental refinement and visualization. While this abstract description applies to virtually any science, the concrete presentation of data and queries offered varies greatly across the individual domains. The result is a repetitive effort in crafting streamlined client interfaces, which is particular tedious in face of interactive graphics. We address this problem by establishing a modular Web client toolkit offering common analysis input and output widgets. The backend generates database queries from the input and displays query results through the output widgets. We present this toolkit, its first implementation version, and an earth science scenario using an Array Database System as retrieval backend. © 2011 IEEE.IEEE Comput. Soc. Tech. Comm. Bus.

Semantic Annotation Pattern For Coding And Its Application In Component Development

Source code annotations have an important role in software development. Structured annotations - those that follow building schemes- provide extra semantics to the code and are suitable for the automatization of complementary development tasks. There are recent initiatives towards interrelating annotations and ontologies, expanding their expressiveness and interoperability. In this paper we propose a new strategy based on meta-annotations to support structured annotations implicitly related to ontologies. It systematizes and simplifies the process of semantically annotating code, since programmers can use annotations without knowing details of the involved ontologies. This strategy was successfully applied in the development of components according to the Digital Content Component (DCC) model, enabling to automatize the production of semantic descriptions and interfaces for components, optimizing the development process. © 2011 IEEE.7180Pressman, R.S., (2002) Engenharia de Software, , 5th ed.

Reusing A Compound-based Infrastructure For Searching Video Stories

The fast evolution of technology has led to a growing demand for multimedia data, increasing the amount of research into efficient systems to manage those materials. A lot of research has being done by the Content-Based Image Retrieval (CBIR) community in the field of images. Nowadays, they play a key role in digital applications. Thus, contextual integration of images with different sources is vital. It involves reusing and aggregating a large amount of information with other media types. In particular, if we consider video data, images can be used to summarize videos into storyboards, providing an easy way to navigate and to browse large video collections. This has been the goal of a quickly evolving research area known as video summarization. In this paper, we present a novel approach to reuse the CBIR infrastructure for searching video stories, taking advantage of the compound object (CO) concept to integrate resources. Our approach relies on a specific component technology to encapsulate the CBIR related tasks and integrate them with video summarization techniques, known as Digital Content Component (DCC). Such a strategy provides an effective way to reuse, compose, and aggregate both content and processing software. © 2011 IEEE.222227 IEEE Systems, Man and Cybernetics Society (SMC),Society for Information Reuse and Integration (SIRI)Achananuparp, P., McCain, K.W., Allen, R.B., Supporting student collaboration for image indexing (2007) Int.
