A single reference view and a set of depth maps are used in the proposed approach. The method not only deals with small disocclusion filling related to small camera baseline, but also manages to fill in larger disocclusions in distant synthesized views. This relies on a coherent tensor-based color and geometry structure propagation. The depth is used to drive the filling order, while enforcing the structure diffusion from similar candidate-patches. By acting on patch prioritization, selection and combination, the completion of distant synthesized views allows a consistent and realistic rendering of virtual viewpoints.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"1 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":"130710389","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}

Therefore, metrics that measure the quality of images that are for end user viewing does not necessarily reflect the quality of depth maps in terms of its ability to render views. This paper investigates the relationship between the quality of the rendered views and different quality measures of the depth map. A novel depth map quality metric is proposed based on a distortion model that approximates rendering errors due to pixel errors in the depth map. The proposed depth map quality metric correlates very well with the quality of the rendered views, as compared to the PSNR and SSIM of the depth map. The application of the proposed depth map quality metric is further illustrated by incorporating the metric at the encoding mode selection stage of a video encoder. Experimental results suggest that with the proposed encoding mode selection scheme bit rate savings of up to 30% can be achieved compared to traditional encoding mode selection scheme based on sum of squared errors.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"27 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":"117241255","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 framework avoids the need to consider an specific encoder architecture for encoding latency analysis by assuming an unlimited processing capacity on the multiview encoder. Under this assumption, only the influence of the prediction structure and the processing times have to be considered, and the encoding latency is solved systematically by means of a graph model. The results obtained with this model are valid for a multiview encoder with sufficient processing capacity and serve as a lower bound otherwise. Furthermore, with the objective of low latency encoder design with low penalty on rate-distortion performance, the graph model allows us to identify the prediction relationships that add higher encoding latency to the encoder. Experimental results for JMVM prediction structures illustrate how low latency prediction structures with a low rate-distortion penalty can be derived in a systematic manner using the new model.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"12 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":"127778411","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}

Audio can be customized through using personalized HRTF. So, listening distortions are caused if HRTFs do not match anthropometric parameters concerning different listeners. In this paper, personalized method is proposed to customize individual HRTF based on non-negative matrix factorization (NMF) and support vector regression (SVR). The anthropometric parameters are selected and high dimensional HRTFs are decomposed into low dimensional matrix using NMF. Nonlinear regression model is derived between the selected anthropometric parameters and low dimensional matrix by SVR. Experimental results demonstrated that personalized HRTF has better performance than using the same HRTF for different listeners in 3DTV audio.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"132 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":"133616079","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 integral imaging the multiperspective information of 3D scenes is stored in a 2D picture. Such picture, composed by a set of elemental images, is obtained through a 2D array of microlenses. The elemental-images set can be used for many purposes. One is the display of 3D color scenes to audiences or much more than one person. Other is the 3D display, with full parallax, in personal monitors, like the screen of a smartphone, a tablet, or the monitor used by a surgeon in an endoscopic operation. Other important types of applications are connected with the topographic reconstruction, slice by slice, of the 3D scene. This is especially important in the case of microscopy applications.

Besides the bandwidth problems caused by the huge data flow, the calculation power needed by the multi-view encoder is an even higher burden than that of a single view encoder. In this paper, a complexity efficient way to encode a single-time instant of 5×3 view frames is presented. Some of the P frames known from the traditional encoding schemes have been replaced by a new type of frame called the D frame, in which the disparity vector of a block in a view can be derived from the other views due to the strong geometrical correspondence existing between adjacent views. Experimental results show that 20.2% complexity gain is achieved without compromising quality and bit-rate by wisely selecting threshold values at different QPs.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"09 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":"127228877","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 allows for a smaller search area which reduces the computational cost of the multi-view encoding system.

Hence, in stereo video encoding the best overall rate vs. perceived-distortion performance may be achieved by asymmetric coding which is reduction of the spatial or quantization resolution of the auxiliary view, while keeping the reference view in full resolution. In this paper, we propose an interactive quality assessment method to evaluate perceptual quality for asymmetric coding of 3D video. Subjective Evaluation of Stereo VIdeo Quality (SESVIQ) is proposed as stereo extension of SAMVIQ (Subjective Assessment Methodology for VIdeo Quality) methodology of EBU. We conducted subjective experiments to compare different algorithms such as symmetric over asymmetric rate allocation or spatial over SNR (signal-to-noise ratio) scaling of the auxiliary view.
