In order to reduce the switching delay, many researches tend to transmit all the views, which brings much more increment in the bandwidth requirement. And the traffic increase as the increase of the number of the views in the multi-view video. In order to overcome these problems, we have proposed a user dependent scheme called UDMVT for the transmission of multi-view video in [1]. And we further improved this scheme to support the 3D multi-view video in the [2]. The evaluation results proved that UDMVT is efficient to reduce the bit-rate of the transmission of the multi-view video in the successive motion model especially when the number of view is larger. In this paper, we will simply introduce the UDMVT and discuss the application of the UDMVT in the Free Viewpoint TV.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"38 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116165319","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 video coding applications mostly concentrate on finding a good trade-off between rate and distortion, the additional constraint of limited processing power has to be considered for mobile applications. Realizing mobile video coding applications for stereo instead of 2D video is challenging, as twice the amount of video data has to be processed. Therefore, we investigate how the trade-off between rate, distortion, and complexity can be optimized for the multiview video coding (MVC) extension of the H.264/AVC standard. In the paper, we focus on the encoder, as its complexity is much higher and more configuration dependent than at the decoder. By enabling and disabling certain tools and setting different parameter values, the encoder complexity can be adapted for mobile applications. The presented results show that an optimized MVC encoder configuration performs significantly faster without impairing the rate-distortion performance.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122707765","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 the proposed method, at first, synthesized images with different depths for a desired view point are obtained by the conventional light field rendering (LFR) method. The synthesized images contain both low and high frequency component artifacts in out-of-focused regions. After that, the proposed dynamic block-based focusing technique is applied to these synthesized images in block by block. Using this process, all in-focus images can be reconstructed. Experimental results show both objective and subjective evaluations compared to the previous works. The proposed method saves processing time and the rendered images have an acceptable quality.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"22 6S 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122815479","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}

Especially, the techniques employed in motion estimation are extended to reduce not only temporal but inter-view redundancies in MVC, but motion vector prediction of a skip mode is only performed in a temporal direction. Therefore, we introduce a temporal skip mode using reference pictures at the same view as the current picture and an inter-view skip mode employing reference pictures at the different views from the current picture. The proposed method decides the best one of the temporal and the inter-view skip modes, based on rate-distortion (RD) optimization. Experimental results illustrate that the proposed method is significantly more efficient than the conventional method.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126155418","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 is expected that after a boom of displays based on active glasses, new display generations will appear. Those would be probably displays with passive glasses, multiview autostereoscopic displays based on parallax barrier or lenticular technology, and displays based on integral photography principles. Each of these types would be outperformed by holographic displays once they eventually mature. Holography is a concept known for a long time to opticians; however, for the computer graphics community it is a new undiscovered world. The tutorial provides basic principles of classical holography for people used to think in terms of rays instead of wave optics, and for those that have little experience with modern optics. These principles are then exploited in a talk about digital aspects of holography and about making holographic renderers. Every participant of the tutorial should be then able to make his or her own basic hologram renderer, to understand principles of advanced ones, and to build a very low budget holographic laboratory.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130008056","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 order to obtain the necessary control over the light exiting the screen a red, green and blue laser source is employed.

This method uses depth information acquired by a depth camera to automatically compute trimaps. Trimaps segment an image into three nonoverlapping regions (foreground, background, and unknown) and generation of a highly accurate trimap is one of the most important tasks in natural alpha matting. We propose an adaptive approach to generate unknown regions according to the fuzziness of the foreground object. Fuzzy regions have wide unknown regions, whereas areas that contain sharp edges have narrow unknown areas. We further extend the standard closed-form matting method to optimize both spatial and temporal domains. Our results show the proposed method significantly reduces flickering artifacts and generates natural 3D scenes.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134378215","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}

Furthermore, the paper discusses the key design issue on compact hardware structure for SDRAM access, which is ultimately achieved in a single general SDRAM by data clustering and integration.
