In this paper, we develop a real-time high-resolution 3D object scanning system based on structured light illumination (SLI). Our system fuses depth information with RGB texture to reconstruct high-resolution 3D point cloud. The point cloud preserves accurate surface geometry of the object (e.g., finger postures of hands, facial expressions, etc). Respectively, for a 640 × 480 video stream, our system can generate phase and texture video at 1500 frames per second (fps) and produce full 3D point clouds at 300 fps. For gesture recognition, we propose to combine the module of robust face recognition with the module of 3D point cloud classification. Moreover, rather than extracting sophisticated features, we leverage the accurate reconstruction and classify each point cloud by directly matching the whole 3D surface geometry with the templates of different classes. The proposed recognition system is robust to the scaling, translation, rotation and texture of objects. Finally, utilizing the system, we contribute to the research community two large-scale high-resolution 3D point cloud databases, i.e., SLI 3D Hand Gesture Database and SLI 3D Face Database. The proposed point cloud recognition approach achieves recognition rates up to 98.0% over the gesture database and 88.2% over the face database in our pilot study.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124057747","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}

Deviance detection aids in the segmentation of auditory objects and is also the basis of bottom-up auditory saliency, which is crucial in directing attention to relevant events. There is growing evidence that deviance detection is executed in the brain through mapping of the temporal regularities in the acoustic scene. The violation of these regularities is reflected as mismatch negativity (MMN), a signature electrical response observed using electro-encephalograpy (EEG) or magneto-encephalograpy (MEG). While numerous experimental results have quantified the properties of this MMN response, there have been few attempts at developing general computational frameworks of MMN that can be integrated in comprehensive models of scene analysis. In this work, we interpret the underlying mechanism of the MMN response as a Kalman-filter formulation that provides a recursive prediction of sound features based on the past sensory information; eliciting an MMN when predictions are violated. The model operates in a high-dimensional space, mimicking the rich set of features that underlie sound encoding up the level of auditory cortex. We test the proposed scheme on a variety of simple oddball paradigms adapted to various features of sounds: Pitch, intensity, direction, and inter-stimulus interval. Our model successfully finds the deviant onset times when the deviant varies from the standard in one or more of the calculated dimensions. Our results not only lay a foundation for modeling more complex elicitations of MMN, but also provide a versatile and robust mechanism for outlier detection in temporal signals and ultimately parsing of auditory scenes.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127992154","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}

Existing research focuses on the optimal design of the hopping pattern, which implicitly assumes that the strategy of the attacker is fixed. In practice, the attacker might adjust its strategy to maximize its damage on the communication system. In this paper, we study the design of optimal hopping pattern (the defense strategy) as long as the optimal jamming pattern (the attack strategy). In particular, we model the dynamic between the legitimate users and the attacker as a zero sum game, and study the property of this game. We show that when the legitimate users and the jammer can access only one channel at any time, the game has a unique Nash equilibrium. In the Nash equilibrium, the legitimate users and Eve will access or jam only a subset of channels that have good channel quality. Furthermore, the better the channel, the larger the probability that Eve will jam the channel and the smaller the probability the legitimate users will access this channel. We further extend the study to multiple access multiple jamming case and characterize the Nash equilibrium. We also give numerical results to illustrate the analytical results derived in this paper.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115999878","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 order to reduce the data transmission cost, small world phenomenon is introduced into WSNs. Networks that do not have the small world structure can be converted to achieve a small world property by the addition of few extra links. The problem is that most large scale WSNs are inherently unstructured and a node has no precise information of the overall model of the network and thus has to rely on the knowledge of its neighbor. For this reason, in most unstructured networks, information is propagated using gossiping. In this paper, we exploit this information propagation mechanism and use Neighbor Avoiding Walk (NAW), where the information is propagated to node that has not been visited previously and which is not the neighbor of a previously visited node. Using this, a novel approach is presented, in which nodes with highest betweenness centrality form a long distance relay path by using a lower order modulation scheme and therefore resulting in a relatively reduced data rate, but maintaining the same bit error rate. Our empirical and analytical evaluations demonstrate that this leads to a significant reduction in average path length and an increase in node degree.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"1958 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128034043","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}
