To achieve that, feature extraction and classification should be accurate and efficient. Feature extraction optimization involves selecting the optimal feature descriptor. Various algorithms in computer vision involve holistic, local and deep learning algorithms. Holistic algorithms analyze the whole facial image and includes algorithms like Linear Discriminant Analysis or fisherfaces, eigenfaces (PCA), Histograms of Oriented Gradients and Gray Level Co-occurrence Matrix (GLCM). Local feature descriptors involve using local facial components separately then aggregating them into a combined histogram. Local binary patterns (LBP), local directional patterns (LDP) and scale-invariant feature transform (SIFT) feature extraction algorithms have been successfully used in local feature extraction. Deep learning involves using convolutional neural networks for image analysis. The most popular models are AlexNet, VGG-Face and GoogleNet. The study evaluates computational accuracy and efficiency of the three forms of facial expression recognition namely holistic, local and deep learning algorithms. The JAFFE and CK+ datasets are used for analysis. Gabor Filters are used for preprocessing filtering of the images whilst Viola Jones OpenCV toolset is used for image visualization. The study concludes that local algorithms compete very well with deep learning algorithms in terms of accuracy but use less processing power than convolutional networks. For real time facial expression analysis with minimal processing power and need for quick response times, LBP algorithms are recommended.","PeriodicalId":386209,"journal":{"name":"2019 Conference on Information Communications Technology and Society (ICTAS)","volume":"85 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113982942","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 application of such technology has become publicly available and has proved its effectiveness as an added layer of security through native applications. Until now, there has been no previous attempt at bringing this solution to a web-based platform supporting real time classification. With frequent reports of websites being exploited and databases being leaked, there is an urgent need for an intelligent security mechanism to overlay the current traditional authentication methods, including usernames and passwords. This paper investigates the possibility of unobtrusive, continuous authentication for web applications based on facial data collected using WebAssembly driven detection algorithms. This novel detection technique has proved the viability to perform real-time image processing on the web with the possibility of achieving near native speeds. This is accompanied with a competitive server side facial recognition rate of 91.67% achieved on the Labeled Faces in the Wild dataset.","PeriodicalId":386209,"journal":{"name":"2019 Conference on Information Communications Technology and Society (ICTAS)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121729169","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 support these students in succeeding with their studies, the learning management system (LMS) needs to be usable; this implies the attributes of effectiveness, efficiency and user satisfaction. The purpose of this study is to propose usability guidelines specifically focused on the requirements for a learning management system in the context of ODeL honours research projects. The study is novel in exploring the supervisors' view of the usability requirements of the LMS. Based on a pragmatic worldview, this study is guided by the design science research (DSR) methodology. The initial set of usability requirements was abstracted from the literature and used as the basis for the LMS evaluation. Usability testing of the LMS was followed by heuristic evaluation, post-test questionnaire and interviews. All evaluations were done with the supervisors as participants. The contribution of the study is the refined usability guidelines based on the triangulation of the findings from the different usability evaluations conducted on the same ODeL LMS.","PeriodicalId":386209,"journal":{"name":"2019 Conference on Information Communications Technology and Society (ICTAS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125367838","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}

Cognitive radio sensor Networks (CRSNs) based SGs uses dynamic RRA for resource allocation to CRSN nodes. However, the challenges associated with sensor nodes in an SG network are: energy or power constraints; poor quality of service (QoS); interference; delay; and problem of spectrum inefficiency. Thus, improvements in resource allocation criteria, such as energy efficiency, appreciable throughput, QoS guarantee, fairness, priority, interference mitigation, etc., will help in circumventing these problems in CRSN-based SGs. Hence, in this work, a new topology and algorithm for improved RRA and QoS guaranteed network connectivity in CRSN-based SGs are proposed. Bit error probability and latency are the metrics used for the investigation of the improved RRA and guaranteed network. The simulation result confirms that the improved model has a very low latency and low error rate at a given signal-to-noise ratio (SNR) compare to the conventional sensor network which has high latency and high error rate at a given SNR.","PeriodicalId":386209,"journal":{"name":"2019 Conference on Information Communications Technology and Society (ICTAS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121699168","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}

Deaf people are disadvantaged in many ways when communicating with the hearing world in real world scenarios, such as hospital visits and in cases of emergency. When possible, Deaf people can enlist the assistance of a family member, community worker or sign language interpreter to assist with such scenarios, however this assistance is pre-arranged and Deaf people would prefer on-the-fly assistance. Our application will assist Deaf people to contact any available sign language interpreter to facilitate communication between the Deaf person and a hearing person using a split screen model, effectively creating a three-way conversation between the Deaf person, the hearing person and the sign language interpreter. The prototype was developed using the WebRTC platform, with JavaScript for browser operability and hardware platform independence. Our hope is that the research can be used to persuade mobile network operators of the need for free or heavily discounted data connection to relay services for Deaf mobile customers.","PeriodicalId":386209,"journal":{"name":"2019 Conference on Information Communications Technology and Society (ICTAS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126943424","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}
