The system is mainly employed for acquisition, storage and retrieval of the real-world urban images with viewpoint information. Here, the images and the viewpoint information are assumed to be collected from the mobile multimedia terminal users. By using the viewpoint information in the database system, an \"Extended Visual Map\" is proposed for presenting the images according to the actual viewpoint of any user; also a position information service is implemented to retrieval the map information by building images. To realize these objectives, the features of the regions containing a building in every real-world urban image are extracted and compared automatically by the proposed system.","PeriodicalId":405589,"journal":{"name":"IEEE International Conference on Multimedia and Expo, 2001.

Commercials are a video category where the link between low level perceptual features and high level semantics is stressed, since the way colors are chosen and modified throughout a spot create a large part of the message. In this paper, we propose a model for representation and comparison of video content based on the spatial arrangement of color flows. A model for representation and comparison of spatial relationships between extended sets of pixels in a 3D space is introduced by developingon the concept of weighted walkthroughs. Results of preliminary experiments are reported for a library of video commercials.","PeriodicalId":405589,"journal":{"name":"IEEE International Conference on Multimedia and Expo, 2001.

These kinds of visual systems are composed of multiple media streams, such as video, audio, text, and image streams, which medium volume is large. Therefore, it is a real challenge to have smooth multiple-stream multimedia presentations over Internet, which usually provides insufficient network bandwidth. In this paper, we propose and develop a multiple-stream multimedia middle-ware named TVMS (The Visual Multicast System). TVMS (i) provides a flexible authoring tool to allow users to author a multiple-stream multimedia presentation in a multicast environment and (ii) achieves smooth multimedia presentations with the temporal control mechanism. This paper describes the major considerations and techniques that are involved in the design and implementation of TVMS. System developers can incorporate TVMS to develop multiple-stream multimedia presentation systems in a multicast environment.","PeriodicalId":405589,"journal":{"name":"IEEE International Conference on Multimedia and Expo, 2001.

For rate control of heterogeneous transcoder, we use the requantization method. Conventional requantization methods for the homogeneous transcoder cannot be used directly for the heterogeneous transcoder due to the mismatch in quantization parameters between MPEG-1 and MPEG-4 syntax and the difference of compression efficiency between MPEG-1 and MPEG-4. In order to solve these problems, we propose a new requantization method for MPEG-1 to MPEG-4 transcoder. It consists of the conventional R-Q model with a simple feedback and an adjustment of quantization parameters with which the output rate of MPEG-4 follows the target rate of MPEG-1. By a simulation of transcoding, it is shown that the proposed requantization can generate output rate much closer to the target rate than the conventional requantization and it gives the superior image quality to the conventional requantization.","PeriodicalId":405589,"journal":{"name":"IEEE International Conference on Multimedia and Expo, 2001.

Mixed Reality (MR) is built around the integration of real world physical and computer generated virtual information. We do not use the term augmented reality (AR) because we view the merging of both worlds as a symbiosis, with desirable properties from each accentuated and complementing each other, rather than the enhancement of one with the other. Collaborative MR allows multiple participants to simultaneously share a physical space while being surrounded by a virtual space that is registered with the physical. Because the MR world inherits the properties of real and virtual worlds, it is rich with social context, spatial cues, and tangible objects from the real world as well as flexible digital information from virtual. We believe that Mixed Reality is a medium, largely unexplored, but very well suited for face-to-face collaboration.","PeriodicalId":405589,"journal":{"name":"IEEE International Conference on Multimedia and Expo, 2001.
