Using a single camera attached to the computer, the system tracks the user's hand in three dimensions and computes up to four parameters in real-time (60 Hz). The system recognizes three gestures that can be interpreted as discrete commands to applications. This system is an off-shoot of an earlier system called Gesture VR that requires multiple cameras. Since the new system uses a single video source it can run readily on a standard home computer equipped with an inexpensive camera and is, therefore, accessible to most users. The system can be used with applications that require 2D and 2D interactions. Examples discussed in this paper include 3D virtual fly-throughs, graphical scene composers and video games.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123364358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional error control schemes are not attractive because they either add redundant information that may worsen network traffic, or rely solely on the inadequate capability of the decoder to do error concealment. As sophisticated concealment techniques cannot be employed in a real-time software playback scheme, we propose a simple yet efficient transformation-based error concealment algorithm. The algorithm applies a linear transformation to the original video signals, with the objective of minimizing the mean squared error if missing information were restored by simple averaging at the destination. We also describe two strategies to cope with error propagations in temporal differentially coded frames. Experimental results show that our proposed transformation-based reconstruction algorithm performs well in real Internet tests.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116363163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, in many contexts this can be inadequate, due to the difficulty for many users to paint significant examples and the impossibility-in many cases-of reproducing complex scenes. 3D interfaces and virtual reality based interaction paradigms offer new possibilities to overcome these limitations. In the prototype system presented, a virtual world can be interactively customized by adding objects to a predefined scene and editing object properties in terms of colours and textures. The system allows the user to navigate the 3D scene. While navigating the virtual world, the user is given the opportunity of taking some photographs used to query by content a database of images.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126520554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It becomes possible to participate in such activities from remote places. Video is one of the best media for this purpose, and it is important to consider how to image such activities. We propose a new video imaging method with multiple cameras for multiple users. Dynamic situations in an activity are defined for describing an imaging rule of each user, and they are detected by processing sensor data. Concretely, the imaging rule is described by a user with camera-works linked to each dynamic situation. With this description of the imaging rules, many users can request their own favourite camera-works, while the system mediates these requests to satisfy as many users as possible. We have built a prototype system and conducted an experiment in which several users could participate in lecture.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125658608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"An architecture of distributed media servers for supporting guaranteed QoS and media indexing","authors":"Feng Cao, Jeffrey D. Smith, Kenji Takahashi","doi":"10.1109/MMCS.1999.778126","DOIUrl":"https://doi.org/10.1109/MMCS.1999.778126","url":null,"abstract":"In a distributed multimedia system, multimedia sessions may get involved with multiple media servers for the retrieval of the media data or the creation of new multimedia documents. To provide the guaranteed Quality of Service (QoS) to real-time applications such as continuous media transfers, the system resources in the media servers must be reserved to avoid contention during execution time. Media indexing is also needed to support searching the media data in such a distributed environment and to provide the necessary information about the usage of system resources for delivering the media data. Due to the overhead, a centralized approach of scheduling all the requests and searching all the media data from only one agent is not efficient, and not scalable. In this study, we propose a new architecture, dividing the media servers into multiple groups of the right size. Within each group, there is a registration agent and an index agent, which take care of the resource reservation, membership management, media indexing searching, and load balancing. We demonstrate how to provide the guaranteed QoS by scheduling the requests among the multiple groups, and show the collaborations between the registration agents and the index agents inside and outside a group. The mobile media servers can fit in this architecture by the updates of membership status from the registration agents. The new IETF drafts such as SIP, RTSP and RTP are embedded into this architecture to support the general multiparty multimedia applications for real-time media streams.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127959239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
