This method combines the advantage of cubic curve fitting interpolation and fuzzy edge interpolation to overcome resolution degradation caused by incorrect motion vector. The intelligent intra-field interpolation scheme alleviates resolution degradation in areas where object motion cannot be well tracked by motion estimation and produces deinterlaced pictures with better visual quality, less flicker, and imperceptible artifacts. Experimental results show that the developed method can indeed generate high quality intra-interpolation picture for motion areas.","PeriodicalId":338920,"journal":{"name":"ITRE 2005. 3rd International Conference on Information Technology: Research and Education, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128271618","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}

These structures have been widely used in applications that deal with discrete dimensions. In this paper we present a brief survey of the different multidimensional models and propose a model that supports both discrete and continuous dimensions with more concentration on the latter. We first define continuous fields. Then we present our model, which is based on discrete and continuous basic cubes. By applying spatial and temporal interpolation functions to a sample of data of the discrete basic cube a continuous basic cube is constructed. Hypercubes are built by applying aggregation functions to basic cubes. Two classes of operations associated with continuous fields are also defined.","PeriodicalId":338920,"journal":{"name":"ITRE 2005. 3rd International Conference on Information Technology: Research and Education, 2005.","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125415403","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 provides an environment to the physicians who at different places for discussing and diagnosing the disease cases. For implementing these functions, the computer-supported cooperative work (CSCW) is adopted in the teleconsultation system. The typical CSCW functions include video and voice conferencing, interactive information exchange, shared workspace, and drawing tools, etc. In order to utilize the resource of network efficiently during the teleconsultation, the data in CSCW should be transmitted by different strategies according to their characteristics. In this paper, we propose a streaming management mechanism for CSCW consultation system used in telemedicine.

In this paper we investigate the risks associated with user's privacy- and location information-control, showing a peer-to-peer-based system framework as a possible approach. The focus is on peer-to-peer LBS relying on the IP multimedia subsystem (IMS), a future extension to GSM/UMTS core networks. A prototype peer-to-peer location-based instant messaging service has been implemented, demonstrating that such services can coexist with current cellular LBS system solutions. In addition to improving subscriber confidence about privacy and security issues in LBS, the proposed system has the potential of making location-service solutions more open and simple, thus leading to greater user acceptance hence prospective LBS market growth in the near future.","PeriodicalId":338920,"journal":{"name":"ITRE 2005. 3rd International Conference on Information Technology: Research and Education, 2005.","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131971382","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}

This design and implementation of the authentication mechanism, which is based on RFC2747, using four commonly adopted hash algorithms - MD5, RIPEMD160, SHA-1, and SHA-256, not only improves security, but also provides useful information from the performance aspect. The time for authenticating the signaling messages depends on the algorithm used, and increases slightly in the order of MD5, SHA-1, RIPEMD160 and SHA-256.

The fault removal continues at a slower rate during the operational phase. In this paper, we will investigate some techniques for software reliability prediction and measurement in the operational phase. We first review how some software reliability growth models (SRGMs) based on non-homogeneous Poisson processes (NHPPs) can be readily derived based on a unified theory for NHPP models. Under this general framework, we can not only verify some conventional SRGMs but also derive some new SRGMs that can be used for software reliability measurement in the operational phase. That is, based on the unified theory, we can incorporate the concept of multiple changepoints into software reliability modeling. We can formularize and simulate the fault detection process in the operational phase. Some numerical illustrations based on real software failure data are also presented. The experimental results show that the proposed models can easily reflect the possible changes of fault detection process and offer quantitative analysis on software failure behavior in field operation.","PeriodicalId":338920,"journal":{"name":"ITRE 2005. 3rd International Conference on Information Technology: Research and Education, 2005.","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124313437","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}
