In a cloud gaming service, the contents of games can be delivered to the clients through either video streaming or file streaming. Due to the strict constraint on the end-to-end latency for real-time interaction in a game, there are still challenges in designing a successful cloud gaming system, which needs to deliver satisfying quality of experience to the customers. In this paper, the methodology for subjective and objective evaluation as well as the analysis of cloud gaming services was developed. The methodology is based on a nonintrusive approach, and therefore, it can be used on different kinds of cloud gaming systems. There are challenges in such objective measurements of important QoS factors, due to the fact that most of the commercial cloud gaming systems are proprietary and closed. In addition, satisfactory QoE is one of the crucial ingredients in the success of cloud gaming services. By combining subjective and objective evaluation results, cloud gaming system developers can infer possible results of QoE levels based on the measured QoS factors. It can also be used in an expert system for choosing the list of games that customers can appreciate at a given environment, as well as for deciding the upper bound of the number of users in a system.","PeriodicalId":164858,"journal":{"name":"2014 IEEE 16th International Workshop on Multimedia Signal Processing (MMSP)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115608697","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}

While many methods have been proposed for recovering spatial layout of rooms in recent years, their performance is still far from satisfactory due to high occlusion caused by the presence of objects that clutter the scene. In this paper, we propose a new approach to estimate the spatial layout of rooms from RGB-D videos. Unlike most existing methods which estimate the layout from still images, RGB-D videos provide more spatial-temporal and depth information, which are helpful to improve the estimation performance because more contextual information can be exploited in RGB-D videos. Given a RGB-D video, we first estimate the spatial layout of the scene in each single frame and compute the camera trajectory using the simultaneous localization and mapping (SLAM) algorithm. Then, the estimated spatial layouts of different frames are integrated to infer temporally consistent layouts of the room throughout the whole video. Our method is evaluated on the NYU RGB-D dataset, and the experimental results show the efficacy of the proposed approach.","PeriodicalId":164858,"journal":{"name":"2014 IEEE 16th International Workshop on Multimedia Signal Processing (MMSP)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126857351","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}

Most existing methods focus on searching for highlight events in soccer videos such as goals, penalty kicks and generating a summary as a list of such events. However, besides highlight events, scenes of intensive competition between players of two teams and emotional moments are also interesting. In this paper, we propose a soccer summarization system which is able to capture highlight events, scenes of intensive competition, and emotional moments. Based on the flow of soccer games, we organize a video summary as follows: first, scenes of intensive competition, second, what events happened, third, who were involved in the events, and finally how players or audience reacted to the events. With this structure, the generated summary is more complete and interesting because it provides both game play and emotional moments. Our system takes broadcast video as input, and divides it into multiple clips based on cinematographic features such as sport video production techniques, the transition of shots, and camera motions. Then, the system evaluates the interest level of each clip to generate a summary. Experimental results and subjective evaluation are carried out to evaluate the quality of the generated summary and the effectiveness of our proposed interest level measure.","PeriodicalId":164858,"journal":{"name":"2014 IEEE 16th International Workshop on Multimedia Signal Processing (MMSP)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959582","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}
