This becomes increasingly relevant and difficult in a distributed environment where new devices and formats can become available at any time and must be taken into account when deciding how to set up a flowgraph of distributed multimedia components.In this paper we present an automatic algorithm for configuring and connecting a high-level flowgraph of multimedia components. Given this abstract flowgraph of participating devices and key components, the algorithm automatically selects necessary additional components, chooses suitable formats, and connects the flowgraph, while trying to achieve the best possible quality.","PeriodicalId":268090,"journal":{"name":"Eurographics Multimedia Workshop","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122946059","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}

The trend to interactive multimedia installation work requires systems that allow participants to interact in subtle ways. The paper describes a number of non-conventional interfaces to computer mediated art works achieved using small Programmable Logic Controllers (PLC) called 'Stamps'. These are programmed in BASIC and can be interfaced to personal computers or used as stand alone devices. They are cheap and extremely versatile in their use for non-conventional interfaces.","PeriodicalId":268090,"journal":{"name":"Eurographics Multimedia Workshop","volume":"37 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125872166","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}

Upon submission of a query request, only a small number of clusters whose buoys are close to the query object are considered for the approximate query result, effectively cutting down the amount of data to be processed enormously. Results concerning the retrieval accuracy from extensive experimentation with a real image archive are given. The influence of control parameters is investigated with respect to the tradeoff between retrieval accuracy and computational cost.","PeriodicalId":268090,"journal":{"name":"Eurographics Multimedia Workshop","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125113562","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}
