The embodiment approach integrates live video into 3D objects for a hybrid participant representation. They implemented their ideas in a Networked Collaborative Virtual Environment system, VLNET and investigated network and rendering issues in comparison with virtual human participant embodiment. The paper presents two distinct case studies demonstrating their ideas. The first one is a tele-teaching application, in which they investigate a shared environment with virtual humans and hybrid embodiments. The second one presents a distributed augmented reality application, in which participants share a mixed environment with real and virtual elements.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

The work done so far fits into the context of one of the recent work-items defined by the ISO/IEC JTC1/SC29/WG11, known world-wide as MPEG. This ISO Working Group is now in the process of defining a unifying framework where natural and synthetic audiovisual objects can be combined and rendered as a unique combination of synchronised interactive media. The developed facial animation system implements the following features: animation of predefined/downloaded face models and animation of face models driven either by speech synthesis applications or by MPEG-4 animation parameters. To improve photo-realism, face models can be texture mapped and calibrated according to the countenances of real people.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

While people in a group share a definite goal, people in a society share their achievements in the form of their knowledge. The augmentation of societies requires a new type of media that can carry varieties of knowledge resources, replicate themselves, recombine themselves, and be naturally selected by their environment. They may be called meme media since they carry what R. Dawkins called \"memes\". An accumulation of memes in a society forms a meme pool that functions like a gene pool. When economic activities are introduced, a meme pool becomes a meme market where providers and distributors of memes carry their business without prohibiting users reediting and redistributing memes. Meme Media Laboratory established in Oct. 1996 are conducting the research on meme media and meme market architectures.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

3D data visualization on the Web Web上的3D数据可视化

Jern","doi":"10.1109/MULMM.1998.722980","DOIUrl":"https://doi.org/10.1109/MULMM.1998.722980","url":null,"abstract":"The paper explains the advantage of using low-cost, configurable, data visualization components, which can be embedded and distributed in electronic documents and reports. With the increasing use of electronic documents, distributed by intranets and the Internet, the opportunity to provide interactive visualization techniques within scientific and engineering reports has become practicable. This new technology of components allows authors of a report to distribute with a specific \"data viewer\", for example, allowing the recipients to interactively examine the data in the same way as the original analyst. A thin client, by definition, have minimal software requirements necessary to function as a user interface front-end for a Web enabled application and raises the issue of client vs. server data visualization rendering. Real-time visual data manipulation doesn't translate well into a \"thin\" client. While the VRML file format allows distribution of visualization scenes to the Web, the user has no access to the actual underlying data source. The \"mapping\" of numerical data into geometry format (VRML) takes place at the server side. Local data manipulation, information drill-down technique, context sensitive menus, object picking and other interactive user interface functions that traditionally have been available on the client are now controlled by the visualization server. In the \"thin\" client model, nearly all functionality is delivered from the server side of the visualization engine while the client perform very simple display and querying functions.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

A typical case of fashion, that of dress, is modeled by cellular spatial structures to show that such algebraic topological modeling can allow a variety of dress designs to be produced from one basic fashion mode, inheriting design characteristics. The basic architecture is a three layered model consisting of a topological layer to specify the basic fashion mode, a geometrical layer to produce varieties of shapes inheriting the topological characteristics, and a visualization layer to implement real dress in wide range of media such as costumes, TV picture content, and publications.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

In order to make this material available to teachers and students in a structured manner, we developed a multimedia database and accompanying tools for creating, manipulating and formatting the teaching content (K. Coninx et al., 1997). Recently, we expanded this educational multimedia database with the functionality to support streamed video as well. Given the vast amounts of data that needs to be stored and transmitted when dealing with streamed video retrieval, we opted to realise a distributed video server. Physically, the distributed server consists of a set of Windows NT PCs, which are interconnected utilising a broadband ATM network. The paper reports on the main implementation aspects of the system.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling. MMM'98 (Cat.

The paper discusses the mapping of high level, application specific features to the visual primitives that are accessible through image processing techniques. A major difficulty is that there are currently no established methodologies for describing the contents of an image in terms of semantic features, and we suggest that semiotic approaches could be adapted to the task of image description in limited areas of expertise. After reviewing current trends in the mapping of high level to low level features, we present preliminary results that suggest a possible strategy for mapping semiotic descriptions to image processing primitives.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

A prediction algorithm is adopted in occasional cases where the estimated result is not acceptable.
