Abstract
A system is disclosed for enhancing video by use of a virtual surface. One or more positions are identified in a first image. These one or more positions are transformed to one or more locations in relation to the virtual surface. In subsequent video images (e.g. fields, frames, or other units), the one or more locations in relation to said virtual surface are transformed to one or more positions in the subsequent video images. The subsequent video images are enhanced based on the one or more transformed positions.
