Such a feature extraction strategy ignores the context of an object in the real world. Taking geometric context into account while classifying various regions in a scene, we can discriminate the similar features obtained from different regions with respect to their context. A geometric context based scene decomposition method is proposed and is applied in a context-aware Augmented Reality (AR) system. The proposed system segments a single image of a scene into a set of semantic classes representing dominant surfaces in the scene. The classification method is evaluated on an urban driving sequence with labeled ground truths and found to be robust in classifying the scene regions into a set of dominant applicable surfaces. The classified dominant surfaces are used to generate a 3D scene. The generated 3D scene provides an input to the AR system. The visual experience of 3D scene through the contextually aware AR system provides a solution for visual touring from single images as well as an experimental tool for improving the understanding of human visual perception.","PeriodicalId":294442,"journal":{"name":"2013, 7th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":"69 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114038855","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 Smart Meter (SM), one of the key elements of the SG, identifies power consumption and communicates with the control center. The long term evolution (LTE) network has become an attractive candidate for SG communications. Regardless of LTE's growing popularity as a means for transporting SG data, it is mainly designed for high speed and high capacity data traffic such as video streaming and internet traffic. Because of the different set of Quality-of-Service (QoS) considered for those applications compared to those required for the SG traffic, LTE is unable to guarantee the delivery of SG data with required QoS levels. As a result, existing scheduling mechanisms may not be able to efficiently handle SM traffic at a heavily loaded eNode-B. Especially, there may not be sufficient resource blocks (RBs) available at an eNode-B for SM traffic. Therefore, in this paper, we introduce a novel scheduling technique for prioritizing SM data for an LTE eNode-B. Further, two RBs are reserved for SG data and each SM is polled periodically by the proposed method. Results indicate that since a guaranteed connectivity could be provided to all SMs, the latency related to SG data is reduced.","PeriodicalId":294442,"journal":{"name":"2013, 7th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116364634","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 likelihood ratio test (LRT) statistic, the maximum likelihood (ML) estimates and Cramer-Rao lower bounds (CRLBs) for this problem are all derived and asymptotic analyses of them are carried out for both high and low SNR regimes. These show that in both regimes the ML estimates are naturally approximated by estimators based on sample moments. While the high SNR results confirm standard practice, the low SNR results demonstrate unexpectedly high sensitivity: for an SNR ρ close to zero the analyses of the LRT statistic and CRLB show O(ρ-4) samples are needed to either reliably detect the presence of a signal or to accurately estimate its parameters. The paper also reviews the iterative method proposed by Li, DiFazio and Zeira (IEEE Commun. Lett. 6(11), pp. 469-471, 2002) for calculating the true ML estimate of SNR: it shows the method to be an instance of the standard bisection algorithm for root finding, and it derives a condition on the sample moments that guarantees existence of a solution and convergence of the algorithm. Finally the paper presents some simulations that compare the iterative scheme with the two standard moment-based estimators and the CRLB: these indicate the widely used M2-M4 estimator based on second and fourth order moments is a good practical choice in many situations.","PeriodicalId":294442,"journal":{"name":"2013, 7th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126869712","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 particular, the SU-Tx and SR are subject to their maximum transmit power limits and the timeout constraint of the primary user (PU). Moreover, we assume that the relay selection is based on either best relay selection (BRS) or max-max relay selection (MMRS). In BRS, a single relay having the best end-to-end channel condition among the SRs is selected for cooperation between the source and the destination. However, the selected relay may not experience the best source-relay channel and relay-destination channel at the same time. To overcome the limitation of selecting the same relay for both reception and transmission, MMRS uses the best relay of the SU-Tx→SR link for reception at the relay and the best relay of the SR→SU-Rx link for transmission to the destination. Specifically, we compare the performance for BRS and MMRS in terms of the outage probability, and study the impact of the number of SRs, PU transmit power and different channel mean powers of interference links on the secondary network performance. Furthermore, based on the performance of the MMRS and assuming that automatic repeat request (ARQ) is implemented for packet retransmission, we investigate the outage probability for delay limited applications. The numerical results indicate that the MMRS outperforms BRS when more than one SRs are deployed. The secondary network outage probability is reduced when the number of SRs and the number of retransmissions become large. It is also shown that the interference from the PU has a significant impact on the secondary network performance.","PeriodicalId":294442,"journal":{"name":"2013, 7th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116609989","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}
