Users can enjoy 3D video simply by choosing a target player and concentrating on a soccer match from the player's view by manually controlling the viewing position. The generated video provides an immersive sight as if the user is running on the pitch. To generate the player views, the target player's 3D trajectory must be estimated. We developed a novel computer vision technique for player tracking that robustly works in an actual soccer stadium. In the current system, the orientation of the virtual camera for the player's view does not follow the gaze direction of each player because the image resolution is too poor to acquire gaze direction by computer vision. Users can choose a favorite orientation control method. We applied the proposed method to an actual soccer match held in an outdoor stadium to confirm its effectiveness.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126111769","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 Random Hole Display (RHD) design eliminates the repeating zones found in regular barrier and lenticular autostereoscopic displays, enabling multiple simultaneous viewers in arbitrary locations. The primary task of a multi-user AS display is to deliver the correct and unique view to each eye of each observer. If multiple viewers see the same pixels behind the barrier, then a conflict occurs. Regular barrier displays have no conflicts between views for many viewer positions, but have significant, localized conflicts at regular intervals across the viewing area and when viewed at different distances from the display. By randomizing the barrier pattern the RHD exhibits a small amount of conflict between viewers, distributed across the display, in all situations. Yet it never exhibits the overwhelming conflicts between multiple views that are inherent in conventional AS displays. With knowledge of user locations, the RHD presents the proper stereoscopic view to one or more viewers. It further mitigates viewing conflicts by allowing display pixels that are seen by more than one viewer to remain active by optionally blending the similar colors of desired views. Interference between views for random hole barriers and for a conventional regular barrier pattern are simulated. Results from a proof-of-concept Random Hole Display are presented.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124660191","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 graphic card of the server computer drives the SLMs and red, green and blue channels are controlled in parallel. Resultant color holographic video is loaded to the SLMs which are illuminated by expanded light from LEDs. In the optics stage, reconstructed color components are combined by using beam splitters.

A very efficient technique is to solve the problem in Fourier space. In this paper we present a fast and simple method to overcome one of the main draw-backs of this approach, namely the large quantization steps. Due to high memory demands, the Fourier-based solution can be computed on low-resolution input only and the resulting rotation estimate is given on an equiangular grid. We estimate the mode of the likelihood density based on the grid values in order to obtain a rotation estimate of increased accuracy. We show results on data captured with a spherical video camera and validate the approach comparing the orientation estimates of the real data to the ground-truth values.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124504563","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 our approach, right image in stereo image and intermediate views are fundamentally predicted and synthesized from left image by 2D image warping using regular mesh and vice versa. To overcome texture distortion on object boundaries and preserve texture smoothness of homogenous areas, we propose node selection on the strong edges in the gradient map. Furthermore, the selected nodes are evaluated by stereo matching error and validated by cross validation for nodal disparity. Each node point is iteratively moving along the pixels with high gradient value instead every point to find the optimal node position. Therefore, our approach provides a fast mesh optimization as well as a reliable image quality. The experimental results show that the proposed approach provides computational efficiency and high PSNR of prediction image compared to previous methods.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129473575","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 performance is judged by increase of quality of view synthesis, which is the main aim of this paper. Experimental results over a variety of moving material demonstrate that considerable gain can be attained without any modifications to estimation core and with tuning of matching stage only. Finally, some guidelines on design of well performing similarity measures are given.

It trades off reconstruction quality for error resilience to provide the best expected reconstruction of 3D mesh sequence at the decoder side. The method is based on partitioning the mesh vertices into two sets and encoding each set independently by a 3D dynamic mesh coder. The encoded independent bitstreams or socalled descriptions are transmitted independently. The 3D dynamic mesh coder is based on predictive coding with spatial and temporal layered decomposition. In addition, the proposed method allows for different redundancy allocations by duplicating a number of encoded spatial layers in both sets. The algorithm is evaluated with redundancy-rate-distortion curves and flexible trade-off between redundancy and side distortions can be achieved.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121169272","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}
