Abstract

A system and method for volumetric display of video images extracted from arbitrary background environments comprising an arrangement for extracting a video image in real time from an arbitrary background and creating a stream of extracted image data in response thereto and a free space or volumetric display operationally adapted to display the stream.

Claims

1. A system for volumetric display of video images extracted from arbitrary background environments comprising:

means for extracting a video image in real time from a chromatically heterogeneous background and creating a stream of extracted image data in response thereto and

a volumetric display operational adapted to display said stream.
