To provide an overview of thousands of images, recent studies have tried to develop a framework for image collection summarization that extracts a smaller set of representative images from the original set. Most existing methods take (a) relevance and (b) coverage of each image into account. However, for the use on mobile devices, several important issues remain: generated summaries must be compact enough so as to suit the small mobile displays but the legibility of the summaries should be sufficient -- but how? Our focus in this paper is to extend the framework of image collection summarization to fit the context of overviewing image search results on mobile devices. The key advances of this paper are to introduce two primary factors of (c) compactness and (d) legibility when generating summaries. Our solution is a two-stage optimization method. Given a keyword query and display size, its first stage ranks the images by taking (a) relevance and (b) coverage into account. The second optimization stage takes into account (c) compactness and (d) legibility and determines the number and sizes of images included in the final summary so as to satisfy the display size constraint. Experiments conducted on over 240,000 images demonstrate the effectiveness of our method.","PeriodicalId":185203,"journal":{"name":"IMMPD '11","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125369416","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}

Recently, with the miniaturization of projectors and the development of embedded systems, there has been an explosion of interest in systems which combine projection technology with computer vision. Associating a projector with a camera offers a cheap means to transform any surface into an interactive display surface. However, it is very hard to segment hand and recognize hand gesture due to self-occlusion, non-rigid tissue, even when the occlusion due to projection content can be avoided. In this paper, a novel approach is proposed to recognize finger stroke under the dynamic illumination circumstances. The approach is based on one projector and two heterogeneous cameras. First, an NIR camera is used to get the finger-tip and hand model, then, the hand model is used to get the interest points of the hand in the visible camera, then we can get the disparity of interest points from the two heterogeneous images. The disparity change is related to the depth change that can be used to determine when stroke event happens. Experiment results from a prototype system show that the approach can run in real-time without using special markers or gloves.","PeriodicalId":185203,"journal":{"name":"IMMPD '11","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129152176","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}
