This book addresses electrical engineers, physicists, designers of flat panel displays (FDPs), students and also scientists from other disciplines interested in understanding the various 3D technologies. A timely guide is provided to the present status of development in 3D display technologies, ready to be commercialized as well as to future technologies. Having presented the physiology of 3D perception, the book progresses to a detailed discussion of the five 3D technologies: stereoscopic and autostereoscopic displays; integral imaging; holography and volumetric displays, and: Introduces spatial and temporal multiplex for the two views needed for stereoscopic and autostereoscopic displays; Outlines dominant components such as retarders for stereoscopic displays, and fixed as well as adjustable lenticular lenses and parallax barriers for auto- stereoscopic displays; Examines the high speed required for 240 Hz frames provided by parallel addressing and the recently proposed interleaved image processing; Explains integral imaging, a true 3D system, based on the known lenticulars which is explored up to the level of a 3D video projector using real and virtual images; Renders holographic 3D easier to understand by using phasors known from electrical engineering and optics leading up to digital computer generated holograms; Shows volumetric displays to be limited by the number of stacked FPDs; and, Presents algorithms stemming from computer science to assess 3D image quality and to allow for bandwidth saving transmission of 3D TV signals. The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics

Stereoscopic displays have become important tools in the fields of molecular modeling, architectural design, computer-aided design, and medicine. These displays significantly enhance the ability of the viewer to comprehend spatial relationships. With the commercial introduction of flicker-free liquid crystal stereoscopic shutters (LCSS), it has become practical to incorporate stereoscopic 3D into moderately-priced graphics workstations, greatly extending the applicability of this display technique. This Project Three-Dimensional Displays for Battle Management, evaluated the 3D stereoscopic display medium for US Air Force applications. We focused on the identification and development of optimized stereoscopic display techniques for the visualization of terrain data. We applied these display techniques to a simulation of a mission planning and rehearsal system to demonstrate the utility of stereoscopic displays. We made advances in the following areas: (1) Display Measurements: (2) Stereoscopic Projection Geometry; (3) Scene Complexity Management Algorithms; (4) Testbed Implementation.

Human Factors of Stereoscopic Displays provides an overview of all vision-relevant topics and issues that inform stereo display design from a user-centric or human factor, perspective. Although both the basic vision science literature and the applied literature will be reviewed, the strength and originality of this book comes from the emphasis on the basic science literature on human stereo vision and its implications for stereo display design. The reader will learn how to design stereo displays from a human vision/human factors perspective. Over the past several years, there has been a growing interest in the development of high-quality displays that present binocular parallax information to the human visual system for inducing the perception of three-dimensional depth. The methods for presenting binocular parallax to an observer vary widely and include three broad categories of display: stereoscopic, holographic and volumetric displays. Because the technology for stereoscopic displays is more developed and more widely used, than those based on holography or volumetric methods, the proposed book addresses those human factors issues involved in the viewing of stereoscopic displays. Despite the diverse methods for creating stereoscopic displays, which includes stereo spatial multiplexing as well as temporal multiplexing (i.e., field sequential) techniques, there remain common human factor issues that arise when viewing such displays. Human Factors of Stereoscopic Displays will provide a detailed review of these important issues so that they can be considered when designing and using 3D displays. In doing so, the following topics will be covered: interocular cross talk; interocular differences in luminance and contrast; accommodation-vergence mismatch; stereoanomaly; spatio-temporal frequency effects; distance scaling of disparity and high-level cue conflict. body>

This thesis outlines the various techniques for creating electronic 3D displays and analyzes their commercial potential. The thesis argues for the use of view-sequential techniques in the design of 3D displays based on considerations of state of the art 3D displays and currently available technology. A view-sequential 3D display was built, which is described in detail. The performance of this display is given, as well as an analysis which characterizes its anticipated performance and comparison with measured results.

This thesis focuses on Intermediate View Reconstruction (IVR) which generates additional images from the available stereo images. The main application of IVR is to generate the content of multiscopic 3D displays, and it can be applied to generate different viewpoints to Free-viewpoint TV (FTV). Although IVR is considered a good approach to generate additional images, there are some problems with the reconstruction process, such as detecting and handling the occlusion areas, preserving the discontinuity at edges, and reducing image artifices through formation of the texture of the intermediate image. The occlusion area is defined as the visibility of such an area in one image and its disappearance in the other one. Solving IVR problems is considered a significant challenge for researchers. In this thesis, several novel algorithms have been specifically designed to solve IVR challenges by employing them in a highly robust intermediate view reconstruction algorithm. Computer simulation and experimental results confirm the importance of occluded areas in IVR. Therefore, we propose a novel occlusion detection algorithm and another novel algorithm to Inpaint those areas. Then, these proposed algorithms are employed in a novel occlusion-aware intermediate view reconstruction that finds an intermediate image with a given disparity between two input images. This novelty is addressed by adding occlusion awareness to the reconstruction algorithm and proposing three quality improvement techniques to reduce image artifices: filling the re-sampling holes, removing ghost contours, and handling the disocclusion area. We compared the proposed algorithms to the previously well-known algorithms on each field qualitatively and quantitatively. The obtained results show that our algorithms are superior to the previous well-known algorithms. The performance of the proposed reconstruction algorithm is tested under 13 real images and 13 synthetic images. Moreover, analysis of a human-trial experiment conducted with 21 participants confirmed that the reconstructed images from our proposed algorithm have very high quality compared with the reconstructed images from the other existing algorithms.
