In order to ensure high precision in indoor environment, DOA estimation techniques have been developed. In this paper, performance of many high resolution methods for Impulse Radio Ultra Wide band (IR-UWB) systems in frequency domain such as ROOT-MUSIC, estimation of signal parameters via rotational invariance technique (ESPRIT) and Matrix PENCIL are evaluated, as well as these techniques are compared also with the performance corresponding to the Cramer- Rae lower bound (CRB). Synthesis results and relevant performance comparisons are presented.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124777422","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 United Kingdom educational system, the government is investing 1.1 million pounds in primary and secondary school for early programming lessoning starting from age five upwards. The ideology behind this innovation is to make younger generation linked to innovation and digital industries and improve the pace with the most successful education system in the world. In this paper, an assessment-driven educational programming tutoring system for young students is described in a high-level overview (which provides an abstract design of the main components of the proposed system), as well as a detailed discussion of some of the existing tutoring programming tools for kids. The intention will be to develop this given proposed design fully functional and then evaluate it in different primary schools from the UK and other Middle East countries. One of our main intended aims of this study would be to offer a suitable educational programming system that could ease the process of teaching and learning programming for kids in primary schooling.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123592755","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 achieve such balance between accuracy and privacy, the web metering scheme has to collect data about users in a privacy-preserving manner. If users are authenticated, it is easy to determine the number of unique visitors; however, authentication and privacy are inherently conflicting requirements. This paper proposes an analytics-based web metering scheme that improves privacy while providing “good enough” accurate results, compared to previous schemes. More precisely, we propose a generic web metering scheme to securely capture data about users in a privacy-preserving manner, and study different scenarios in which the scheme can be implemented. Each scenario is described, outlining assumptions and techniques. The scenarios and underlying techniques can be used as improvements to the privacy of existing schemes (like Google Analytics) while maintaining accurate results.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121461704","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}

For classifying a HOI event normal or abnormal and subsequently classifying the potential abnormal categories requires the knowledge of the mutual relations between the Human, object and the ambient environment. Researchers have been using various contexts like spatial, temporal, sequential etc. to classify the abnormal actions. In this paper, we have introduced a novel context of object's affordance (which is a semantic map of the human, object and the ambient environment) to identify abnormalities in Human Object Interactions. Furthermore, the sub-classification of the abnormalities is also realized. In order to achieve our goal, we have introduced a set of novel attributes associated with the Human and the Objects and mapped them in a Bayesian network framework. The inference capabilities of the system depict the successful identification of abnormal events. We have also initiated a novel dataset of abnormal Human-Object Interactions in domestic settings. This research work also made a valiant effort to capitalize the abundant statistical data sources currently available, related to the domestic accidents and use them to nourish a practical classifier.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114376812","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}

One of the most known fraud is the bypass fraud, which is used in international calls in order to avoid access charges and making profits. This kind of fraud causes severe losses in revenue to operators with other negative side effects. In this paper a new fraud detection technique is proposed. The proposed technique depends on user profiling and using fuzzy logic. Fuzzy logic was used in decision making process by utilizing fuzzy logic membership function. A real database from mobile operator company Almadar Aljadid in Libya is used in this investigation. Five features are extracted and employed as detection patterns in the proposed technique. The five features or detection patterns are, subscriber's mobility, incoming to outgoing calls ratio, suspicious cell activity, irregular calls, and service type.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128269120","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}

Among the most prominent of these communications are the social networks that have made communication easy and fast between individuals. Twitter is one of the social networks that have grown significantly in recent years. Due to the dynamic nature of its timeline, hidden tweets to the followers decreases the activity level with them. Thus, this forms a major challenge for the tweeter. We aim to solve this problem by proposing system that use a novel algorithm dedicated to discover the appropriate times to tweet based on the analysis of the active followers usage behavior.

Dense HetNet, which requires progressive introduction of Femtocells, offers scalable networks towards 1000 fold gains in capacity as per technology vision for 5G. In such dense networks, the problem of interference comes between the Macrocells and Femtocells as well as among the Femtocells themselves. Valuable insights in the Macro-Femto interference are available, while the Femto-Femto interference aspects remain partially addressed. This paper outlines this problem and points potential solution strategies to mitigate the Femto-Femto interference, increase the network capacity, decrease the power consumption and likewise reduce the CO2 footprint. According to the system level simulation of our novel power control framework, user throughput is 15,9% to 49,3% greater than that of the conventional power control schemas. This is equal to 9,87 to 12,35kg CO2 emission reduction per year for one Femtocell BS.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125168932","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 eccentricity transform computes the longest geodesic distance across the object. This transform is invariant to translation and rotation. The maximal eccentricity points yield diameters across the image. We compute the Euclidean distances from the boundary to the diameter to characterize the curvature of the shape. Our shape descriptor is comprised of the best matches retrieved from the normalized histogram of the eccentricities, the Hausdorff distance between the set of distances to the diameter and a measure of the number of points lying on either side of the diameter along with the peak values. We evaluate this descriptor on 2D image databases consisting of rigid and articulated shapes by ranking the number of matches. In almost all cases, the shapes are matched with at least one shape from the same class.","PeriodicalId":419122,"journal":{"name":"International Conference on Computer Vision and Image Analysis Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131995157","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}
