In this paper, we present a system to interactively enhance the viewing experience of synchronized video streams in 3D space. Our system automatically computes the relative positions of all cameras and enables smooth transition between videos in 3D space. We are proposing a new approach to transition between videos. Other methods in viewpoint navigation demand a lot of computation for estimating depth...
Conventional autostereoscopic quality assessment focuses on the physical properties and not on the perceptual aspects; however, the user visual quality verifications, especially in mobile gaming, is also crucial since personal experience determines the success of these products. For evaluating the quality features of autostereoscopic displays, especially in terms of viewing angle or viewing field,...
Welcome to the fifth (5th) edition of the “International Conference on 3D Imaging (IC3D)”, which is technically co-sponsored by the IEEE Signal Processing Society, and the proceedings of which are archived in the IEEE Xplore digital library.
This study investigated the contribution of stereoscopic depth cues to the reliability of ordinal depth judgments in complex natural scenes. Participants viewed photographs of cluttered natural scenes, either monocularly or stereoscopically. On each trial, they judged which of two indicated points in the scene was closer in depth. We assessed the reliability of these judgments over repeated trials,...
The design of autostereoscopic display devices is mainly based on the formation of different viewing zones respective to expected positions and interpupillary distances of observers. We developed a generic model approach for the description of light ray distributions through common kinds of optical image splitters. The calculation of viewing zones is based on our subpixel area model. As a novel feature,...
Film is about engagement with the audience. Drawing the audience into a story so as to forget everything else for the time they are watching that movie requires a suspension of disbelief by the audience. Those who develop technology for creative purposes have had at their heart a remit to give filmmakers the ability to give audiences less and less reason to break this suspension of disbelief by creating...
Present multi-view display techniques are often based on the use of multi-pass algorithms, one per view usually besides an additional step for image compositing. Generally linearly dependent on the number of views, these approaches introduce a bias by incorrectly considering that depth information is located at the pixel level, while the sub-pixel level would be more suitable to improve the intrinsic...
This paper presents a novel method for creating omnistereo images using longer focal lengths. The purpose of this study is to give the viewer with head mounted displays (HMD) or cardboard headsets a more cinematographic experience and to enable content creators to overcome present limitations in the aesthetics of virtual reality image recording. The presented method demonstrates the camera setup,...
In this paper we present the realization of a 3D virtual museum tour through the use of paired full-panoramas, to be displayed using the Head-Mounted Display “Oculus Rift”. The paper analyzes in details every stage of the project, from the starting point, i.e. the collection of the required images, to the end, that is the creation of the tour itself. The proposed solution is conceived to be developed...
Over recent years, television sets have increased in size steadily while also decreasing in price. S3D content has also become more easily accessible, with lowering prices and an improvement in content quality. We are interested in how these developments have been reflected in viewing habits and particularly the distance at which today's large televisions are viewed from. This study measured the viewing...
In this paper, the tolerance of the brightness and the color distortions of stereoscopic images are discussed based on extensive experimental studies. We explore the tolerance of the brightness and distortions, including overall luminance difference, white clip level inconsistency, black clip level inconsistency, and color distortions, between left and right images. The experiment result demonstrates...
With the rapid maturing of 3D printing technologies, research on optimizing models to be printed in geometrical perspective has been considered; for example, model hollowing, partitioning. Much of these works however do not deal with the basic property that has to be determined in every 3D printing moment: model orientations. In this paper, we propose a novel approach to find reasonable orientations...
In this paper we present a method for the generation of 3D stereo (3DS) pairs from sequences of historical aerial photographs. The goal of our work is to provide a stereoscopic display when the existing exposures are in a monocular sequence. Each input image is processed using its neighbours and a synthetic image is rendered, which, together with the original one, form a stereo pair. Promising results...
Various watermarking schemes achieved the robustness against the usual operations such as simplification, remeshing and noise addition. However, the techniques were not robust against cropping, nevertheless the cropping attack is commonly performed by general editing. In this paper, we propose a robust 3D mesh watermarking method against cropping. We achieve the blind watermarking scheme involving...
The bandwidth and storage restrictions of consumer devices and conventional delivery infrastructures on stereoscopic 3D video require efficient compression methods to save the bandwidth and preserve the perceptive quality at the same time. Compression efficiency is actually determined as the visual quality achieved for a certain amount of bitrate. In this paper, a perception aware coding scheme is...
Depth-Image-Based Rendering (DIBR) is an effective 3D image generation method. It has been widely used by virtue of its low bandwidth requirements and depth adjustment capability. However, the development of an effective copyright protection scheme of DIBR images remains a challenging task. Digital watermarking has been applied with a great success in recent years to provide copyright protection for...
Stereoscopic 3D viewing (S3D) can create a clear and compelling improvement in the quality of the 3D experience compared with 2D displays. This improvement is distinct from any change in the amount of depth perceived, or the apparent 3D shapes of objects and the distances between them. It has been suggested instead that the enhanced feeling of realness is associated more with the precision with which...
