Hardware encoder manufacturers have adopted their product lines to support the dynamic adaptive streaming over HTTP but suffer from the inflexibility to provide scalability on demand, specifically for event-based live services that are only offered for a limited period of time. The cloud computing paradigm allows for this kind of flexibility and provide the necessary elasticity in order to easily scale with the demand required for such use case scenarios. In this paper we describe bitcodin, our transcoding and streaming-as-as-ervice platform based on open standards (i.e., MPEG-DASH) which is deployed on standard cloud and content delivery infrastructures to enable high-quality streaming to heterogeneous clients. It is currently deployed for video on demand, 24/7 live, and event-based live services using bitdash, our adaptive client framework.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121855485","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}

However, disocclusion is a critical problem that the regions occluded by foreground objects become visible in virtual views, which is difficult to be visual-plausibly inferred. In this paper, we propose a novel temporally consistent filling method using multiple sprites with depth (MSD) to fill the disocclusions faithfully. MSD stores the background as well as intermediate foreground objects of past frames in multiple sprites, so that amounts of pixels in disocclusions can be recovered from MSD. Moreover, we also introduce a method to recognize the source space for exemplar based inpainting to fill the remaining disocclusions. The experimental results show the proposed method achieves objective and subjective improvement compared with the state-of-the-art methods. The synthesized sequences by the proposed method have higher spatio-temporal consistency.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134490846","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}

As compared with previous learning-based VQA methods, it has two unique features. First, EVQA adopts a frame-based learning mechanism to address the limited training data problem. Second, a dynamic image quality assessment(IQA) fusion scheme is developed by taking three factors into account: the spatial complexity and temporal context of a frame in a video source and the strength of IQA indices. In the test stage, EVQA applies the derived IQA fusion rule to different frames and take an average of the frame-based scores to generate the final video quality score. The superior performance of the proposed EVQA index is demonstrated by experimental results conducted on both LIVE and MCL-V video databases.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133131195","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}

Currently a smart city is no longer focused just on offering administrative services, but on providing useful and pervasive information to citizens and serving as basic data source for local companies to create value added services. Live Fallas combines Future Internet enablers developed for Smart City platforms in the framework of FIContent2 project to provide a mobile application aimed at a large scale event, such as the Fallas Festival. Open data fusion, real time social network analysis and context-aware recommendation are the most relevant functionalities offered to users.

Most of these studies ignore the potential confounding effects of a sequence of these factors with a specific time lag between them and asthma outbreaks. In this paper we present a new method for identifying consequential relations in the form of complex patterns between environmental factors and asthma attacks. Temporal structure and order relation between these data and their effect on asthma exacerbation comprise complex patterns called asthma risk factors. By extracting such patterns we create a risk prediction model that is important both for an asthmatic patient and public health. For experimental evaluations, we have collected pollution and meteorological data in Tokyo city and found 32 complex risk factor patterns that might result in asthma outbreaks. The experimental results show that extracted model has 71.15% precision.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"293 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114528384","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 modality in fact possesses several properties which may be appealing for automatic people recognition, such as the intrinsic liveness detection and the robustness against potential attacks. Moreover, it could be easily exploited in applications based on brain-computer interfaces (BCI). In this paper we exhaustively analyze the discriminative capability of a compact representation of EEG signals acquired in resting conditions. Specifically, the exploited templates are obtained as projections into a subspace defined through EigenBrains (EBs), a basis for EEG data relying on principal component analysis (PCA). An extensive set of experimental tests, conducted on a database comprising 60 users, is performed to evaluate the recognition capabilities of the proposed representation under different system configurations.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126225800","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}
