Tutorial on Immersive Imaging Technologies: from Capture to Display

V-SENSE Research Fellows Dr. Martin Alain, Dr. Cagri Ozcinar, and Dr. Emin Zerman, will be presenting a tutorial on “Immersive Imaging Technologies: from Capture to Display” at IEEE ICME 2020. We are looking forward to seeing you there!



The advances in imaging technologies in the last decade brought a number of alternatives to the way we acquire and display visual information. These new imaging technologies are immersive as they provide the viewer with more information which either surrounds the viewer or helps the viewer to be immersed in this augmented representation. These immersive imaging technologies include light fields, omnidirectional images and videos, and volumetric (also known as free-viewpoint) videos. These different modalities cover the full spectrum of immersive imaging, from 3 degrees of freedom (DoF) to 6DoF, and can be used for virtual reality (VR) as well as augmented reality (AR). Applications of immersive imaging notably include education, cultural heritage, tele-immersion, remote collaboration, and communication. In this tutorial, we cover all stages of the immersive imaging technologies from content capture to display. The main concepts of immersive imaging will first be introduced, and creative experiments based on immersive imaging will be presented as a specific illustration of these technologies. Next, content acquisition based on single or multiple camera systems is presented, along with the corresponding data formats. Content coding is then discussed, notably ongoing standardisation efforts, followed by adaptive streaming strategies. Immersive imaging displays are then presented, as they play a crucial role in the user’s sense of immersion. Image rendering algorithms related to such displays are also explained. Finally, perception and quality evaluation of immersive imaging is presented.
