Indeed, we propose to bring an improvement to an existing content based image retrieval approach.

This method can cluster various numbers of photons adaptively. The scenes in adjacent frames are similar, and so most photons have the same moving paths in adjacent frames. Therefore, most photons do not need to be shot again in the next frame. Regional photon clustering employs a quadtree structure to track the trajectory of dynamic objects to reduce the number of re-shot photons. Experimental results show that regional photon clustering reduces the number of re-shot photons, and accelerates the estimation of global illumination in dynamic scenes","PeriodicalId":107275,"journal":{"name":"2006 12th International Multi-Media Modelling Conference","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127314134","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 these systems, all visual features are extracted from these images and used to determine relevant images from the database. As a result, users are left to decide whether or not to include images that not only contain desirable features but also irrelevant ones. Fewer examples or a contaminated set of more either would compromise the retrieval effectiveness of most similarity measures. In this work, we examine this popular case when desired features present in image examples define the intent of the queries. We show how this consideration affects the selection of the representative query points and retrieval sets, and discuss the options whether or not to retrieve partially relevant images.

With this, creators can not only integrate and author multimedia data of all sorts through drag-and-drop into desired interactive scenario courseware, but also can quickly and easily reuse the completed courseware. Apart from these, this system is developed conforming to the SCORM standard. The completed courseware can be applied on the learning management platform that is corresponding to the SCORM standard.

The complicated computational relation among the distributed data can be extracted and maintained in spreadsheet by using a language called SCRL.

This paper introduces a new silhouette-based framework for inferring human pose from monocular uncalibrated camera and pays more attention on how to retrieving 3D body pose by matching 2D silhouette based on shape context. Finally we retrieve a group of 2D silhouettes from one human motion which has two different viewpoints. By many experiments, the rate of 2D silhouette matching we got is been proved more accurate than that generated by using other methods we have known in this field. To accelerate the matching process of calculating shape context, we use PCA (principal components analysis) to reduce the computation of complexity.
