Abstract
A system and process for rendering and displaying an interactive viewpoint video is presented in which a user can watch a dynamic scene while manipulating (freezing, slowing down, or reversing) time and changing the viewpoint at will. The ability to interactively control viewpoint while watching a video is an exciting new application for image-based rendering. Because any intermediate view can be synthesized at any time, with the potential for space-time manipulation, this type of video has been dubbed interactive viewpoint video.
