Within the scope of this paper, we investigate the case of crowdfunding in Finland and identify particular national needs and potential what this new phenomenon has. The phenomenon of the Crowdfunding has been growing at a rapid pace in Finland, with it being seen as fundraising and effective marketing tool. Especially start-ups have started using the power of the crowd to promote their ideas and products as well as to raise funding. They are very opened to use Crowdfunding as an additional source of finance during their first round of financing. The effect of global platforms like Kickstarter and Indegogo, and in addition successful national ventures like Timo Vuorensola's campaigns for the new movie Iron Sky popularised Crowdfunding in Finland demonstrates the power of this instrument. In particular the younger audience is opened for this new tool. Within the scope of this paper we analyse the power of Crowdfunding in the Finnish context based on a literature study, and analysis of data gathered from Crowdfunding platforms.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125830285","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 theoretic model, now known as the sequential coding model, abstracts consecutive frames as correlated random variables. Even the most efficient High Efficiency Video Coding (HEVC) standard can be roughly described by this sequential coding model. Searching for methods and algorithms which can improve the coding efficiency of HEVC is an attractive yet formidable task. In this paper, we propose a sequential coding model with backward refinement (BR). In this modified sequential coding model, after each frame is reconstructed, it can be backward refined by the frames encoded afterwards. Note that the proposed BR model does not depend on the coding tools and thus can be implemented on any current video coding standard. So, using this BR model, we can further improve the coding efficiency of any video coding standard, with only slight modification of the coding structure. Theoretical analysis is given on the performance of the BR model. We also propose a BR algorithm for the practical purpose, which is implemented on the HEVC standard. Experiment results show a maximum of 2.2% BD-rate saving compared with original HEVC codec.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129365456","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 this paper, we propose an effective and easy-to-use algorithm for interactive image segmentation (IIS) on mobile phones through integrating a Bayesian Classifier into the Random Walk optimizer. We exploit the user input information to train a Bayesian classifier for determining the posterior probabilities of the image pixels belonging to foreground or background. These probabilities are used to calculate the edge weights and label the seed pixels in the random walk optimizer for image segmentation. The resultant method is called BCRW for short. In this way we improve the segmentation accuracy and alleviate the user burden. The user is only required to draw a rectangle bounding the interested object to get the high-quality segmentation result. We further design an efficient mobile phone version of our BCRW algorithm. The effectiveness and efficiency of the proposed algorithm is confirmed by the comparative experimental results with the Grab Cut and the PIBS algorithms, as well as the experimental results on a mobile phone.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125496576","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}
