This system involves huge amount of data and requires a metadata database system to enable user to retrieve the desired media efficiently. This paper proposes a multi-level abstracted metadata DB design to retrieve every day experiences in various ways with a user-friendly web interface. The simulated performance with real lifelog media data shows that suggested multi-level metadata DB structure can retrieve experience media data around four times more efficient compared with usual single-level annotation-based metadata database in the sense of retrieval time.","PeriodicalId":234433,"journal":{"name":"2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124740556","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 iterative procedure, mean shift, is the key point to find the most credible target location. Though it performs well in some bad conditions, such as camera motion, partial occlusions, and background clutters, it has limited performance on tracking the object with the changing size. In this paper, the adaptive filters were modified and integrated with the mean shift process to estimate both the object position and the matrix describing the kernel shape. The previous states on both the position and the matrix are used to predict and maintain a better approximation of the kernel scale and orientation. Some experiments prove the superior performance of our new method. It has advantages in tracking the objects changing in scale or orientation and is less prone to the background clutter and occlusions.","PeriodicalId":234433,"journal":{"name":"2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System","volume":"2008 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127311436","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}

Though under-reported in the literature, the performance of a segmentation algorithm depends on the choice of input parameters. The paper reports wide variety both in evaluation time and segmentation results for an example mean-shift algorithm. When testing extends over an algorithmpsilas parameter space, then the search for satisfactory settings has a considerable cost in time. This paper considers the use of a genetic algorithm (GA) to avoid an exhaustive search. As application of the GA drastically reduces search times, the paper investigates how best to apply the GA in terms of initial candidate population, convergence speed, and application of a final polishing round. The GA parameter search forms part of a three-component computation environment aimed at automating the search and reducing the evaluation time. The first component relies on scripted testing and collation of results. The second component transfers to a commodity cluster computer. And the third component applies a genetic algorithm to avoid an exhaustive search.","PeriodicalId":234433,"journal":{"name":"2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125161614","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}

In this paper, we propose an efficient strip-mining algorithm for improving SRF bandwidth utilization on Imagine. Firstly, we present how to determine the optimal kernel set for strip-mining. The process is based on a novel structure proposed by us, namely kernel reuse graph. Secondly, we select the optimal strip size, so as to achieve the tradeoff between stream reuse and stream prefetching. Finally, we propose the efficient strip-mining algorithm, which is implemented in Scompiler. The experiment results show that our strip-mining algorithm is a practical and promising solution to improve SRF locality and hide the memory access overhead effectively on Imagine.","PeriodicalId":234433,"journal":{"name":"2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123070143","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}

Public Web services that are available \"on the Web\" provide unlimited values for a great number of online service consumers and developers. However, the public UDDI Business Registry - the primary service discovery mechanism over the Internet - has been shut down permanently since 2006. This has raised serious problems for public Web services discovery. In this paper, we propose a WSDL-based public Web service discovery approach. It provides a simple-to-use yet effective Web service discovery mechanism that can retrieve relevant Web services directly from the Internet to suffice various requirements. The major contributions of this paper include: (1) a review on the state-of-the-art WSDL-based Web services discovery approaches; (2) the unique WSDL crawling and manipulation algorithms catering for the Vector Space Model, and (3) a proof-of-concept prototype - an online Web services search engine - based on the proposed approach.","PeriodicalId":234433,"journal":{"name":"2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131036338","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}

Most of the grid data management and data replication solutions deal purely with read-only data sets. There is a lack of the tools that enable the management of updatable grid database replicas. This work presents a set of services for the replica content synchronization, which are designed to support relational and XML data resources, provide the interoperability of heterogeneous systems and enable the utilization of proven methods for consistency handling to synchronize replicas in the heterogeneous grid environment. The main component of proposed system is the update propagation service that coordinates the functionality of other involved middleware services.

Previous work on ATN mainly focuses on how to protect sensitive information about negotiators. However, the efficiency and success, which are primary goals of ATN, are not sufficiently considered. In this paper, we extend existing policy languages by adding two basic and expressive operators to them, which is one key to improve negotiation efficiency. Several problems that can not be effectively solved using traditional policy languages are presented, they can be effectively and efficiently settled by the extended policy languages, and several examples are also given. Furthermore, we develop an associated protocol taking advantages of oblivious signature based envelope (OSBE) and two new concepts explored in this paper. We also prove that the extended policy languages and the associated protocol together greatly improve negotiation efficiency and success under some conditions without sensitive information leakage in ATN.","PeriodicalId":234433,"journal":{"name":"2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114070066","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}
