“…The perimeter length, L of the upper-half hexagon is given as (2) If the cross-sectional area of the trapezoid is C a then (3) The N rate of change of L can be expressed as (4) By taking the maximum of (4) into consideration, the allowable cross-sectional area, C a of the trapezoid can be obtained as in (5). The expression in (6) implies that the area of the trapezoid is approximately twice the area of a square of side N.…”

“…This approach requires little geometric information and can give potentially photorealistic results but requires many more input images [9,10]. These two approaches can be thought of as opposite extremes of a spectrum where a reduction of one resource, geometric completeness, requires a corresponding increase in another, the number of images, to maintain a consistent quality.…”

“…With these systems, the user can experience more free interactive navigation in the scene [33,70,68]. These systems typically employ image-based rendering (IBR) which is a technique to generate the novel view from multiple views of the scene recorded using multiple cameras [65,41].…”

High-spatial-resolution videos offer the possibility of viewing an arbitrary region-of-interest (RoI) interactively. The user can pan/tilt/zoom while watching the video. This chapter presents spatial-random-access-enabled video compression that encodes the content such that arbitrary RoIs corresponding to different zoom factors can be extracted from the compressed bit-stream. The chapter also covers RoI trajectory prediction, which allows pre-fetching relevant content in a streaming scenario. The more accurate the prediction the lower is the percentage of missing pixels. RoI prediction techniques can perform better by adapting according to the video content in addition to simply extrapolating previous moves of the input device. Finally, the chapter presents a streaming system that employs application-layer peer-to-peer (P2P) multicast while still allowing the users to freely choose individual RoIs. The P2P overlay adapts on-the-fly for exploiting the commonalities in the peers' RoIs. This enables peers to relay data to each other in real-time, thus drastically reducing the bandwidth required from dedicated servers.
