Although one of the five components of the specification for UHDTV, ITU-R Recommendation BT.2020 in 2012, it is only when it became apparent that HDR could help accelerate the slow penetration of 4K into the TV and home-cinema market, that HDR suddenly started to gain significant attention. But what exactly is HDR? Dynamic range is defined as the difference between the largest and smallest useable signal. In photography this has meant the luminance range of the scene being photographed. However, as HDR grows as a “marketing tool” this definition is becoming less “black & white”. This paper considers the different ways in which the term HDR is now being exploited; the challenges of achieving a complete efficient HDR pipeline from capture to display for a variety of applications; and, what could be done to help ensure HDR algorithms are future proof as HDR technology rapidly improves.","PeriodicalId":404025,"journal":{"name":"2016 Digital Media Industry & Academic Forum (DMIAF)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115062331","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, inappropriate exercises cannot help exercisers build desired muscles, and may even get them hurt. In this paper, we proposed a 3D plank-coaching system to guide plank exercisers through fusing multimodal data and providing proper haptic feedback to them. Our proposed system can measure and fuse the user's muscle movements, posture, and several physiological parameters information, which are collected from Electromygraphy (EMG) sensors, Kinect v2 sensors, Electrocardiography (ECG) sensors, and thermometer. Based on comparison results between the user's fused data and the standard data, our system can activate the corresponding vibrotactile actuators, embedded in our developed haptic clothes, to suggest the correct adjustments. As a result, our system can improve the user' plank exercise quality and decrease his/her injury risk.","PeriodicalId":404025,"journal":{"name":"2016 Digital Media Industry & Academic Forum (DMIAF)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123244186","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}

Because of throughput variations, video adaptation methods are needed to avoid buffer underflows. In this context, it is also important to evaluate the overall video quality of a session. In this paper, we investigate a quality model that can evaluate a session quality as well as different adaptation strategies in real time. We use the histogram of segment quality values and the histogram of quality gradients in a session to model the overall video quality. Then, our quality model is employed to evaluate, for the first time, the cumulative quality of typical adaptation methods in real time. It is found that, to provide a high quality level, the client should avoid changing versions frequently and drastically.","PeriodicalId":404025,"journal":{"name":"2016 Digital Media Industry & Academic Forum (DMIAF)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131451650","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 has lead to a number of recommendations from the EU at a national and at an EU level [1]. In Germany, a “law on safe communication and applications in healthcare” (so called eHealth-law) has been passed by the German government in December 2015 [2]. It aims to accelerate the introduction of eHealth in Germany and includes mandatory milestones. The key aspects are an emergency health record, which must be implemented by 2018, an electronic medication plan, an electronic exchange of medical data and an EHR, which has to be implemented by the end of 2018. However, it remains arguable if such a law will be enough to facilitate the further development of eHealth.","PeriodicalId":404025,"journal":{"name":"2016 Digital Media Industry & Academic Forum (DMIAF)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133411893","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}

An end effect was found for both better TQ and worse TQ videos. However the peak effect was found for bad, but not good, videos.

Professional photographers often work with complex lighting setups to directly capture an image close to the targeted one. Some photographers reversed this traditional workflow. Indeed, they capture the scene under several lighting conditions, then combine the captured images to get the expected one. Acquiring such a set of images is a tedious task and combining them requires some skill in photography. We propose a fully automatic method, that renders, based on a 3D reconstructed model (shape and albedo), a set of images corresponding to several lighting conditions. The resulting images are combined using a genetic optimization algorithm to match the desired lighting provided by the user as an image.","PeriodicalId":404025,"journal":{"name":"2016 Digital Media Industry & Academic Forum (DMIAF)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125823788","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}

Yet previous works on medical records search did not pay attention to it.

In this paper, we propose a Temporal Bag-of-Words model to represent medical records as document sequence. In which framework, we adopt Dynamic Time Warping algorithm to calculate the temporal similarity between sequences. Then a clustering-based combination method is proposed for re-ranking.
