Recently, the advent of next-generation GPGPU replaced the traditional way of exploiting the graphics hardware. We have migrated real-time depth image-based rendering - for use in contemporary 3DTV technology - and noticed however that using both GPGPU paradigms leads to a higher performance than non-hybrid implementations. Using this paper, we want to sensitize other researchers to reconsider before migrating their implementation completely, and use our practical migration rules to achieve maximum performance with minimal effort.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"1 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":"130406739","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}

Stereo video enables 3D television, but as mobile services are subject to various limitations, including bandwidth, memory, and processing power, efficient compression is required. Three of the currently available MPEG coding standards are applicable for stereo video coding, namely H.264/AVC with and without stereo SEI message and H.264/MVC. These methods are evaluated with respect to the limitations of mobile services. The results clearly indicate that for a certain bitrate inter-view prediction as well as temporal prediction with hierarchical B pictures lead to a significantly increased subjective and objective quality. Although both techniques require more complex processing at the encoder side, their coding efficiency offers the chance to realize 3D stereo at the bitrate of conventional video for mobile services.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"37 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":"126631161","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 multiview plus depth representation provides a lower bit rate when it is encoded than multi-view and higher resolution than a 2D-plus-depth sequence. Scalable video coding provides adaption to the conditions at the receiver. In this paper we propose a scheme that combines scalability in both the view and depth domain. The center view data is preserved, whereas the data of the side views are extracted in layers depending on distance to the camera. This allows a decrease in bit rate of 16–39 % for the colour part of a 3-view MV depending number of pixels in the first enhancement layer if one layer is extracted. Each additional layer increases the visual quality and PSNR compared only using center view data.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"18 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":"121619382","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 light rays pass through the lens array and form an optical image, part of which enters the observer's pupil and forms an image on the retina. It was assumed that the pupil has a certain diameter. The depth range of the 3D image (whose projected image on the retina is sampled by the lens array) was derived. That is, the depth range is restricted to the surrounding area of the lens array and depends on the pitch of the elemental lenses constituting the lens array. When the reconstructed 3D image is located within the depth range, its visual resolution is limited by the Nyquist frequency. On the other hand, when the 3D image is located out of the depth range, the visual resolution can be increased to the upper limit of frequency by diffraction of the elemental lens.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"21 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":"114155899","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}

Currently, multiview LCD optical plate autostereoscopic display device is common in the art, while the composition method is limited[1,2]. A new general multiview LCD stereo image composition method is proposed in this paper based on the optical plate LCD stereo display device. The proposed method mainly consists of three steps: sub-pixel judgment, sub-sampling of sub-pixel of each view, arrangement and composition of sub-pixels. The proposed method covers all possible cases of the optical plate LCD stereo display device. It has good universality and applicability.

One of the key elements in 3DTV is the multi-view video coding, obtained from a set of synchronized cameras, capture the same scene from different view points. The video streams are synchronized and subsequently used to exploit the redundancy contained among video sources. A multi-view video consists of components for data acquisition, compression, transmission and display. This paper outlines the design and implementation of a multi-view video system for transmission over a wireless channel.

Two MPEG coding standards are applicable for video plus depth coding, namely MPEG-C Part 3 and H.264 Auxiliary Picture Syntax. These methods are evaluated with respect to the limitations of mobile services and the achievable quality for rendering the second stereo view from compressed video plus depth.

However if the stereoscopic image captured by the toed-in camera system with fish-eye lens is displayed on mobile device, it is uncomfortable to view because the horizontal parallax contain horizontal parallax distortion occurred by the wide field of view of the lenses. Therefore, in this paper, we propose a novel correction method of the horizontal parallax distortion, which is one of the keystone distortions. We have experimented to attest the proposed method. The captured stereoscopic image was corrected for the barrel distortion and the horizontal parallax distortion. Therefore, the proposed method provides correcting of the horizontal parallax distortion from a toed-in camera system in order that users can enjoy three-dimensional effects without the visual fatigue.","PeriodicalId":230128,"journal":{"name":"2009 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video","volume":"120 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":"123491393","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}
