Numerous object detection schemes have been designed to process each frame independently. However, in many applications, object detection is performed using video data, which consists of a sequence of image frames. Thus, the object detection accuracy can be improved by exploiting the temporal context of the video sequence. In this paper, we propose a novel video object detection method that exploits both the motion context of the object and spatio-temporal aggregated features to enhance the video object detection performance. First, the motion context of the object is extracted by the correlation operator between the feature maps of two adjacent frames. In addition to generating the motion context, the spatial feature maps for N adjacent frames are aggregated to boost the quality of the feature map with gated attention network.","PeriodicalId":282243,"journal":{"name":"2020 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114631903","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}

There is a way to monitor power for PV failure detection, but it is necessary to connect a device for measuring power at all PV. Therefore, PV Farm owners have to more spend cost for monitoring as number of PV. In this paper, we propose a monitoring system that does not require connection of power sensors, communication modules and processors to each PV. For this purpose, generated power is modulated depending on specified frequency band.","PeriodicalId":282243,"journal":{"name":"2020 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"123 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114719071","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 street lighting with intelligence for safety service is called smart lamppost and composed of an intelligent edge unit, camera, short range communication device, digital signage, etc. One of the main functions in the smart lamppost is to forward the safety information to the gateway node by an I2I communication system. Due to the nature of safety services, latency and throughput of the wireless mesh network are key performance indicators. There has been lack of research on street light network. In this paper, we analyze the latency and throughput at each node during multi-hop data transmission to the gateway node considering the practical height and location of the street light pole with channel interference and propagation path loss.","PeriodicalId":282243,"journal":{"name":"2020 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114721403","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}

Many research groups paid attention to machine learning algorithms in order to deal with big data and massive connection. The mMTC systems are one of key 5G applications. It requires massive connection. Clustering is one of key research challenges to design mMTC systems. K-means clustering algorithm is one of the simplest unsupervised machine learning algorithms. The purpose of this algorithm is to find a cluster in data by iteratively minimizing the measure between the cluster centre of the group and the given observation. In this paper, K means clustering algorithms are applied for mMTC clustering problem. New metrics for clustering mMTC devices are proposed.

The T-algorithm, which makes feasible to eliminate unnecessary additions and comparisons, can be applided to the 4D-8PSK-TCM to lower the decoding complexity. In this paper, we design the 4D-8PSK-TCM simulator with Hybrid T-algorithm based on deep learning to lower decoding complexity.

We present the proposed scheme for cost-effective compressive sensing for wideband spectrum sensing with a large number of distributed SUs. SUs have a single RF-chain for the compressive sensing and the measurement samples obtained at each SU are sent to the fusion center. The fusion center performs the proposed algorithm which estimates the minimum measurement samples for the reconstruction process. Among the total measurement samples by SUs, the rest of the samples except for the minimum number of samples are used for cooperative spectrum sensing. The original signal vector with the minimum measurement samples is reconstructed and cooperative gain is obtained by using the remainder of measurement samples effectively. We compare the performance of the proposed algorithm with the conventional compressive sensing scheme and the result shows that the proposed algorithm has better performance specially at the high sparsity order region.","PeriodicalId":282243,"journal":{"name":"2020 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"2007 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127309030","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}
