We propose an efficient semi-automatic depth map generation scheme based on limited user inputs and depth propagation. First, the original image is over-segmented. Then, the depth values of selected pixels and the approximate locations of T-junctions are specified by user inputs. The final depth map is obtained by depth propagation combining user inputs, color and edge information. The experimental results demonstrate that our scheme is satisfactory in terms of both accuracy and efficiency, and thus can be applied for high quality 2D to 3D video conversion.","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":"125953540","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}

As a popular camera calibration approach, minimal solution method gives rise to a great number of focal-length estimates, from which generating an accurate one is of great significance. Our method concentrates on how to obtain an accurate estimate and is carried out in two steps: firstly, a norm constraint for the fundamental matrix is employed to prune the low-confidence focal-length candidates. Then the focal-length estimate is obtained with a robust focal-length estimation scheme, which consists of occurrence to probability transform, focal-length candidates resample and final estimation with expectation. Experimental results demonstrate that our method could obtain better estimate with both higher accuracy and higher stability than the state-of-the-art method.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"22 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":"134141730","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 normal estimation and position adjustment of each point is required for this procedure. We present a mathematical analysis of the normal estimation approach, and propose two hypotheses to determinate the accuracy and smoothness of the points in a local region. A multi-scale strategy is implemented to obtain a proper scale for each point. Then the according normal is calculated by PCA on this scale, and the positions can be optimized by combining the accurate neighboring normals. A 2D toy example proves that the proposed approach can adjust the noisy point to the right surface while preserving details. At last we show that our method can improve the quality of mesh models for real MVS reconstruction tasks.","PeriodicalId":158764,"journal":{"name":"2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON)","volume":"41 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":"131877861","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 human visual system is known to fuse left and right views in such a way that the perceptual visual quality is closer to that of the higher-resolution view. In this paper, a subjective assessment of mixed resolution (MR) stereoscopic videos is presented and the results are analyzed and compared with previous subjective tests presented in the literature. Three downsampling ratios 1/2, 3/8, and 1/4 were used to create lower-resolution views. Hence, the lower-resolution view had different spatial resolutions in terms of pixels per degree (PPD) for each downsampling ratio. It was discovered that the subjective viewing experience tended to follow a logarithmic function of the spatial resolution of the lower-resolution view measured in PPD. A similar behavior was also found from the results of an earlier experiment. Thus, the results suggest that the presented logarithmic function characterizes the expected viewing experience of MR stereoscopic video.","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":"132829060","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}

Recently, we proposed a depth up-sampling method which uses the high resolution view in the process of depth up-sampling. Actually, in 2007 Kopf et.al. already proposed a Joint Bilateral Upsampler(JBU), which uses a high resolution input image as prior in a joint bilateral filter for upscaling. In this paper we compare our previous method with the JBU approach, in the context of depth coding.

To accurately evaluate the predictors, we also propose a measure that minimizes the impact of errors in the depth information and view-dependent image signals.

For the experimental service, stereoscopic 3D video signals are encoded with 35 Mbps and transmitted over single broadcasting channel by using the existing cable headend and transmission systems. Prototypes of the software-based 3D encoder and 3D STB were also used for the experimental service. Through the experimental broadcasting service, it was possible to provide HD 3DTV broadcasting service under legacy cable environment and to support backward compatibility for the conventional 2D STBs to receive HD broadcasting by using the reference video.
