2010 was the year of breakthrough for 3D video. Stereoscopic 3D is established in cinema, on Blu-ray, TV, PCs, laptops, and mobile devices. Since technology for stereo 3D is mature and content creation is understood well enough, these developments are expected to be sustainable this time. Most current systems rely on classical approaches to 3D video, i.e., representation as stereo or multiview video,...
Extending the frontier of visual computing, sound rendering utilizes sound to communicate information to a user and offers an alternative means of visualization. By harnessing the sense of hearing, audio rendering can further enhance a user's experience in a multimodal virtual world and is required for immersive environments, computer games, simulation, training and designing next generation human-computer...
3D displays are now rapidly designed, enhanced and sold. It is expected that after a boom of displays based on active glasses, new display generations will appear. Those would be probably displays with passive glasses, multiview autostereoscopic displays based on parallax barrier or lenticular technology, and displays based on integral photography principles. Each of these types would be outperformed...
In HELIUM3D a glasses-free (autostereoscopic) display is under development by an eight member consortium with funding from the European Union. The project commenced in 2008 and will finish in June 2011. This display is designed to supply 3D to several users by employing the principle of head position tracking so that the positions where stereoscopic image pairs can be observed, referred to as exit...
Integral imaging is a rising 3D imaging technique that can be considered the incoherent version of holography. 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...
Capturing 3D scenery, processing the captured data for storage and transmission, and displaying the result for creating 3D visual sensation are the main functional components of a 3DTV system. 3DTV-CON 2011 is the 5th in a series of successful conferences bringing together researchers and developers with diverse experience and activity in distinct, yet complementary, areas in relation to 3D television...
Recent years have seen a surge in interest in 3D entertainment. Cinema goers have flocked to view 3D movies in large numbers, which has encouraged broadcasters to introduce 3DTV channels. At the same time, advances in display technology, have resulted in more affordable stereoscopic displays being made available to the consumer. While delivering stereoscopic 3D video to the general publics' homes...
In this study, we propose a heuristic methodology for modeling the end-to-end distortion characteristics of an error resilient broadcast system for 3D video over Digital Video Broadcasting - Handheld (DVB-H).We also use this model to optimally select the parameters of the video encoder and the error correction scheme, namely, Multi Protocol Encapsulation - Forward Error Correction (MPE-FEC), minimizing...
This paper presents a technical development and broadcast trials of 3D service over digital multimedia broadcasting (DMB). Generally, 3D broadcasting has some considerations such as the 3D content delivery, rendering for generating of virtual-view image and glassless comfort viewing. These kinds of consideration seem more important in mobile broadcasting domain. Because, most of the mobile broadcasting...
This paper presents a three-dimensional television (3DTV) trial broadcasting service that has been recently launched in Korea. The 3DTV trial broadcasting service employs a delivery mechanism of 3D content, called as dual stream method that delivers left and right images over each encoded stream based on MPEG-2 system technology, guaranteeing backward-compatibility. Specifically, this dual stream...
We present a multi-view 3D video acquisition and its processing system for multi-view 3D television (3DTV). The proposed hybrid camera system consists of three-color cameras and one time of flight (TOF) camera. Since currently available TOF cameras do not provide color images associated with the depth image, we use a beam splitter between the color camera of the center view and the TOF camera to minimize...
The designed circular holographic display system produces ghost-like 3D optical reconstructions of a computer generated 3D model. System uses six phase-only reflective-type spatial light modulators (SLMs) that are configured circularly. Alignment of the SLMs are successful and gap problem is solved by using half-mirrors. The total number of pixels of the resultant display is 11520 × 1080. Reconstructions...
Under many viewing circumstances, asymmetric stereoscopic video coding provides similar perceived quality with significant decrease in bitrate, computational complexity, and memory usage compared to conventional stereoscopic video coding. However, in other circumstances, users may prefer conventional symmetric stereoscopic video to asymmetric stereoscopic video. This paper presents a stereoscopic...
We implement a viewing angle enhanced integral imaging system by the use of more than one lenslet arrays placed in a curve-like manner. The curve effect providing widened viewing angle is achieved, from the nature that we approximate a curved lenslet array using three flat lenslet arrays. To confirm the feasibility of pickup in real time, a digital reconstruction is carried out. It is revealed that...
Generating in-between images from multiple views of a scene is a crucial task for both computer vision and computer graphics fields. Photorealistic rendering, 3DTV and robot navigation are some of many applications which benefit from arbitrary view synthesis, if it is achieved in real-time. GPUs excel in achieving high computation power by processing arrays of data in parallel, which make them ideal...
This paper presents a stereo video encoder optimization for mobile applications. While video coding applications mostly concentrate on finding a good trade-off between rate and distortion, the additional constraint of limited processing power has to be considered for mobile applications. Realizing mobile video coding applications for stereo instead of 2D video is challenging, as twice the amount of...
