Systems for rendering arbitrary views of natural scenes have been well known in the computer vision community for a long time but only in recent years[when?]
Restricted free viewpoint television views for large environments can be captured from a single location camera system mounted on a moving platform.
Systems with more physical cameras can capture images with more coverage of the viewable scene, however, it is likely that certain regions will always be occluded from any viewpoint.
A larger number of cameras should make it possible to obtain high quality output because less interpolation is needed.
In terms of hardware, the user requires a viewing device that can decode MVV and synthesize new viewpoints, and a 2D or 3D display.
