Download or read book Interactive Focus of Light Fields for 3D Displays written by Karen A. Lin and published by . This book was released on 2007 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: We desire to render scenes onto 3D displays for realtime applications based on image data, targeting media such as streaming multi-view video. The conventional method for rendering would be to first perform 3D reconstruction of the image data, then render the 3D geometric and texture data. However, this approach would be too slow and would lack robustness for complex scenes. Instead, we take an image based approach by using appropriate filtering. Our approach interpolates limited light field data of a 3D scene to simulate depth of field, so that we are able to render new stereo pair views from camera array data in realtime. This allows users to roam in front of a 3D display and still experience seamless natural viewing. We produce these images by convolving 2D image data with an elliptical Gaussian. By shearing the line-like Gaussian to minimize variance over an area-of-interest, the application determines the depth of a user designated pixel. This lets users change focus in realtime, so that their vision does not feel inhibited by the shallower focal depth. Instead, they are able to better focus on the details of their current interest. Our method can be combined with eye trackers and video data for minimally invasive surgery, video conferencing, or any other remote controlled interactive visual applications for enhanced realistic viewing experience.

Download or read book Introduction to Holography written by Vincent Toal and published by CRC Press. This book was released on 2022-12-13 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully updated second edition of Introduction to Holography provides a theoretical background in optics and holography with a comprehensive survey of practical applications. It is intended for the non-specialist with an interest in using holographic methods in research and engineering.

Essential practical requirements for successful holographic recording are explained in detail. Recording materials are considered with detailed discussions of those in common use. Properties peculiar to holographically reconstructed images are emphasised as well as applications for which holography is particularly suitable. Mathematical tools are introduced as and when required throughout the text with important results derived in detail. In this new edition, topics such as photopolymers, dynamic holographic displays, holographic optical elements, sensors, and digital holography are covered in greater depth. New topics have been added, including UV and infrared holography, holographic authentication and encryption, as well as particle beam, X-ray, and acoustic holography. Numerical problems are provided at the end of each chapter. This book is suitable for undergraduate courses and will be an important resource for those teaching optics and holography. It provides scientists and engineers with knowledge of a wide range of holographic applications in research and industry, as well as an understanding of holography’s potential for future use.

Download or read book Cameras and Display Systems Towards Photorealistic 3D Holography written by Jin Li and published by Springer Nature. This book was released on 2023-11-26 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent advances in three-dimensional (3D) imaging and display frameworks, encompassing three categories of 3D imaging and display technologies. The first category is nonphotorealistic 3D approaches based on conventional optical cameras to implement 3D stereoscopic observation of a scene. In the context of nonphotorealistic 3D imaging and reconstruction systems, the authors introduce general principles and also demonstrate camera calibration for 3D imaging, smart cameras, and full-link imaging methods using the optical modulation transfer function to improve imaging quality in conventional cameras. The second category is based on light-ray light field technology to achieve photorealistic 3D imaging and displays. In the context of light-ray light field systems, two approaches capable of light-ray light field 3D imaging by utilizing a camera array or a lens array are demonstrated. Accordingly, light-ray light field display approaches comprising head-mounted displays and integral displays are also introduced. The third category is also photorealistic 3D imaging and display technology, which is based on holography (i.e., diffraction or wavefront light field). In the corresponding holographic displays, the authors introduce 3D holographic displays from three elements: algorithms, devices, and systems, involving fast hologram generation algorithms, wide-viewing-angle display systems, and metasurface holography, etc. Including an investigative roadmap for future progress in optical imaging and 3D display systems, this book is essential reading for scientists and engineers in academia and industry who are interested in next-generation imaging and display concepts for 3D visual sensing systems.

This book was released on 2005-11-24 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1st International Conference on Virtual Storytelling took place on September 27–28, 2001, in Avignon (France) in the prestigious Popes’ Palace. Despite the tragic events of September 11 that led to some last-minute cancellations, nearly 100 people from 14 different countries attended the 4 invited lectures given by international experts, the 13 scientific talks and the 6 scientific demonstrations. Virtual Storytelling 2003 was held on November 20–21, 2003, in Toulouse (France) in the Modern and Contemporary Art Museum “Les Abattoirs.” One hundred people from 17 different countries attended the conference composed of 3 invited lectures, 16 scientific talks and 11 posters/demonstrations. Since autumn 2003, there has been strong collaboration between the two major virtual/digital storytelling conference series in Europe: Virtual Storytelling and TIDSE (Technologies for Interactive Digital Storytelling and Entertainment). Thus the conference chairs of TIDSE and Virtual Storytelling decided to establish a 2 year turnover for both conferences and to join the respective organizers in the committees. For the third edition of Virtual Storytelling, the Organization Committee chose to extend the conference to 3 days so that more research work and applications could be be presented, to renew the Scientific and Application Board, to open the conference to new research or artistic communities, and to call for the submission of full papers and no longer only abstracts so as to make a higher-level selection.
