Since the most relevant object that attracts our attention in surveillance videos is human face, we focus in this paper on building a system for indexing surveillance videos based on human face features. The proposed system has three main stages: Video Surveillance Summarisation, Face Detection, and Facial Feature Descriptors, and Indexing. A keyframe selection technique based on local foreground entropy is used for video surveillance summarisation. In the Face Detection stage, a skin color based method using measurements derived from the color-space components of the keyframe is used to locate eye, mouth and face boundary. Subsequently, SURF algorithm is applied to extract the feature descriptors of interest point from the detected face region. These descriptors are then indexed using vocabulary tree. The integration of the above-mentioned methods that are all good in their results, have made our overall system robust and efficient. Therefore, good results have been obtained while testing in ChokePoint public dataset contains 48 video sequences with a total of 179 349 frames including 64 204 face images.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"10067 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120960744","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}

SaaS is based on Service Oriented Architectures and Web Service technology which are popular paradigm to design new generation of applications. These functionalities are published on the Internet, but exploiting rigorously a large data stream in order to use Web Services is a complicated and laborious task which may involve error prone. In this paper we investigate the problem of SaaS Web Service Composition. We present a new technique that translates the problem of minimum SaaS Web Services composition into MaxSAT problem. We extend this encoding to take int account the QoS by proposing a weighted MaxSAT version.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127244127","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 is because learning or practicing mathematics demands highly visual abilities. In this paper, a framework is introduced which will enable visually impaired students to learn and practice mathematics like sighted students. The framework was instantiated successfully to enable visually impaired students to learn and practice linear algebra. An electronic system was developed which was used by visually impaired university students. In addition, an instantiation was implemented to help visually impaired upper elementary and middle school students learn and practice Algebra using either Arabic or English. This instantiation has been implemented as an electronic system and tested for upper elementary students. Encouraging results were reported. Currently work is ongoing to augment it to serve middle school students.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"54 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129209609","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 majority of printed dictionaries organize ArSL signs (represented in drawings or pictures) based on their nearest Arabic translation; so unless one already knows the meaning of Arabic sign, dictionary look-up is not a simple proposition. In order to build Arabic signs recognition system, standard database of Arabic signs is required to validate the results, however, this database is absent. In this paper, we introduce the ArSL database, a large and expanding public dataset containing video sequences of thousands of distinct ArSL signs. The database is collected using digital camera, Microsoft Kinect 2 sensor and Leap motion tracking sensor. This dataset is created as part of a project to develop an Arabic sign language translator. This database contents and variations qualifies it to be a benchmark database for ArSL in both research and commercial purposes.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122293473","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}

It helps them understanding what they read, express their thoughts and communicate with others. Despite this importance, vocabulary acquisition remains a hard task which requires a higher motivation level. On the other hand, learning games are considered as one of the effective ways for increasing learner's desire to learn. This paper presents an accessible version of the popular crosswords game for deaf learners. It allows learning Arabic vocabulary in a fun and interactive way. The game was used by 38 learners. The obtained results showed that the game enhances the learners' level of knowledge regarding Arabic vocabulary.

Our module is a component of the framework PMAF (Personalized Mobile Assessment Framework) that aims to provide personalized mobile assessment resources. The use of semantic web technologies is explained with the feature of ensuring data interoperability and reuse of mobile feedback resources. In addition, an investigation for the enhancement of the defined feedback in IMS/QTI specification is presented. In our approach, a personalized mobile feedback module based on web services uses the learner's information stored in his/her e-portfolio to continuously suggest the most appropriate and personalized feedback in a particular field of knowledge to ensure the achievement of learning goals.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134434682","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}
