From the single action to complex interaction activity, it is necessary an efficient model to describe the relationship of body components between multi-human objects. In this research, the authors proposed a hierarchical model based on the Pachinko Allocation Model for interaction recognition. Concretely, the joint features comprising joint distant and joint motion are calculated from the skeleton position and then support to topic modeling. The probabilistic models describing the flexible relationship between features - poselets - activities are generated by this model. Finally, the Binary Tree of Support Vector Machine is applied for classification. Compared with existing state-of-the-arts, the proposed method outperforms in overall classification accuracy (8-21% approximately) with the SBU Kinect Interaction Dataset.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127992139","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 scene background is firstly modeled by a novel algorithm, namely Neighbor-based Intensity Correction, which identifies and modifies motion pixels extracted from the difference of the background and the current frame. Concretely the first frame is assumed as an initial background to be updated at each new coming frame based on the mechanism of the standard deviation value comparison. Two pixel windows used for standard deviation calculation are generated surrounding a corresponding motion pixel from the background and the current frame. The steadiness of the current background at the pixel-level is measured by a constantly updating factor to decide the usage of the algorithm or not. In the next stage, the foreground of the current frame are detected by the background subtraction scheme with an optimal Otsu threshold. This method is evaluated on various well-known datasets in the object detection and tracking area and then compared with recent approaches via some common quantitative measurements. From experimental results, the proposed method achieves the better results (approximately 5-20%) in term of the foreground detection accuracy.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133537725","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}

To solve this problem, in this paper, we propose Sector-Chain Based Clustering (SCBC) Routing Protocol, in which, entire network area is divided into sectors (clusters), which balance to the number of nodes. SCBC further reduces energy dissipation of communication in network by constructing chain for each cluster with the chain leader as the cluster head (CH) or secondary cluster head (SCH) that has high residual energy and the shortest distance between candidate nodes and base station (BS) in network. In addition, SCBC improves energy efficiency by calculating the time length of each round in the steady data transmission phase for CHs or SCHs but still guarantee that it is alive in next round. Our simulation results show that the network lifetime of our proposed protocol can be improved about 70% and 20% in comparison with PEGASIS (Power-Efficient Gathering in Sensor Information System) and IEEPB (An Improved Energy-Efficient PEGASIS-Based) protocols, respectively.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130509077","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}
