Unlike the original approach which introduces the same regularization term based on the inter-scale regularizer parameter to control the cost consistency among the multi-scales for all regions of the input images. We propose an adaptive regularization term in order to take into account the local structure of the image. For this purpose, we use the popular three-component image model to parse the reference image, then obtain the edge, texture and flat regions. Then, for each region, a regularizer parameter is defined. Experiments were conducted on the KITTI benchmark and obtained results have demonstrated the efficiency of the presented algorithm since significant erroneous disparities are effectively reduced.","PeriodicalId":113688,"journal":{"name":"2017 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125569105","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}

This paper proposes a color texture analysis method based on the graph theory, in which we convert the texture in question into an undirected weighted graph and explore the shortest paths between four pairs of pixels according to different scales and orientations of the image. Basically, we extend two previously introduced approaches that consider the RGB color space, to textures in the HSV color space taking into account the nature of correlations between its color channels. In order to evaluate its performance, we applied this procedure to USPTex textures dataset. The best classification results using the standard parameters of the method are 92.25%, 91.75% and 85.72% of Accuracy (percentage of samples correctly classified). Which proves the efficiency of the proposed method compared to the results achieved by traditional methods found in literature.","PeriodicalId":113688,"journal":{"name":"2017 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"1776 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129552885","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}

With the emergence of software defined network (SDN) and NFV, the mobile network operators (MNOs) that are deploying the IMS look to make a gain from these leading technologies to mitigate hardware costs and reduce time to market. With the use especially of the NFV approach, the MNO looks for scaling services up and down fast and also reduce costs to align with network usage. In this paper, we give an introduction to a virtualized IMS based telecommunications platform called Telecom Cloud Manager as a virtualized and extended architecture of the 4G/LTE system, being defined by the 3GPP, toward a proposed five generation (5G) paradigm. We intend to migrate all IP switching layers to virtualized entities, including servers and network elements, by using one of the leading virtualization technologies and concepts involving a cloud manager, and an NFV framework. On that account, we set up a testbed system with the goal of evaluating the behavior of a virtualized IMS core network, as part of telecom operators' networks, within a static service provisioning context. Experiment results show that resource performance could be enhanced quickly in the case of unforeseen degradation by supporting a new VNF based service chain.","PeriodicalId":113688,"journal":{"name":"2017 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124553911","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}

VPN technology allows the connection between these different sites, while giving the user the benefit of the security. New Generation VPN technologies allow to create multiple virtual tunnels between various devices in a fast, automatic and dynamic manner. However, existing technologies represent limitations of reliability, which means, the security policy deployed in a domain or a cloud, will be applied on all sorts of traffic whatever its type. This paper proposes a new model of adaptive security that we have called Smart Security Management for New Generation VPN. This model allows to generate security policies in an automatic, intelligent and adapted way to the performances of the transported applications and the network status. That is, if the network is overloaded and the flow to be transported is of real-time type, then generate a policy of medium, low security level or even not secure if the organization allows it in the contract.","PeriodicalId":113688,"journal":{"name":"2017 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129219959","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}

Fully homomorphic encryption (FHE) is a smart category of encryption schemes that allows working with the data in its encrypted form. It permits us to preserve confidentiality of our sensible data and to benefit from cloud computing powers. Currently, it has been demonstrated by many existing schemes that the theory is feasible but the efficiency needs to be dramatically improved in order to make it usable for real applications. One subtle difficulty is how to efficiently handle the noise.
