The most popular used approach to adjust depth of a scene is changing the baseline distance. The baseline distance can be changed by generating virtual views, using view interpolation or extrapolation. But these kinds of approaches change the depth of objects, but the size of objects. As a matter of fact, the size of an object is one of the factors that give 3D depth perception. The proposed scalable multiplexing changes the size of an object as well as the disparity of a scene. The proposed method changes the size of an object with varying the downscaling ratio during multiplexing stage. Not only can it enlarge the size of an object without any quality loss, but it can also adjust depth of an object by shifting it. As a result, we confirmed that it is possible to adjust the depth and change size of the ROI by enlarging the ROI gradually and shifting it pixel by pixel in 3D display.","PeriodicalId":111565,"journal":{"name":"2013 3DTV Vision Beyond Depth (3DTV-CON)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121103451","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 aims to find the rotation and translation differences between the point clouds. A key component in the algorithm is finding correspondences between the two data sets, which are then used to determine the differences. A method for finding these pairings is described, utilizing the circular trajectory of points when the cloud is being rotated. The proposed method reveals more information per iteration cycle than techniques previously used for 3D data. The method enables the use of an efficient implementation by using a simple data structure, which has the same computational complexity to build and to access as the k-d tree commonly used with nearest neighbor correspondence searches. The experimental results show that the convergence rate is superior to the original ICP based on point-to-point minimization and compares favorably to more refined and complex approaches, e.g. normal shooting with point to plane minimization. This together with the efficient implementation strategy and low amount of computation per iteration makes the circular trajectory correspondences (CTC) a valid choice for registration tasks, especially in applications where processing power is limited.","PeriodicalId":111565,"journal":{"name":"2013 3DTV Vision Beyond Depth (3DTV-CON)","volume":" 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113949122","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}

We propose a hole-filling algorithm to fill the disocclusion holes in the virtual view by exploiting the temporal information of the reference views. We also propose an algorithm to avoid the shining of background pixel through a foreground object in the virtual view due to the absence of foreground pixel information. We generate different zoomed views of the scene by applying the concept of view synthesis and observe the variation of holes with different zoom scales. Finally, we propose and demonstrate depth based image segmentation to facilitate parallel computing. Experimental results show that good quality virtual views are generated with high PSNR and with fewer artifacts.","PeriodicalId":111565,"journal":{"name":"2013 3DTV Vision Beyond Depth (3DTV-CON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128202218","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 based on zero-padding the predefined projected intensity and calculating an extended phase distribution using an optimized iterative approach based on the generalized projection method. The extended phase distribution is divided into several finite ones with the size of the spatial light modulator (SLM). The SLM manipulates an incident plane wave to generate the projected intensity at a remote plane. Utilizing the temporal-multiplexing property of a phase-only SLMand incoherent superposition of the redundant intensities projected across the observation plane reduce the speckle effect. In contrast to the state of the art, no mechanical moving parts and no additional information are required during the projection process. The basic principle of this technique and its experimental verification are described.","PeriodicalId":111565,"journal":{"name":"2013 3DTV Vision Beyond Depth (3DTV-CON)","volume":"517 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123101617","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 results of this comparison are presented with regard to coding performance and quality of the base and virtual views. In the light of these results, the 2D+Z format turns out to be competitive over a broad range of requirements for the delivery of consumer auto-stereoscopic 3D TV. Such a format is much easier to implement and to compress than competing 3D+2Z solutions. It can better deal with low quality depth maps and it doesn't need to bother with left-right consistencies.","PeriodicalId":111565,"journal":{"name":"2013 3DTV Vision Beyond Depth (3DTV-CON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133750336","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}
