A Virtual Restoration Stage for Real-World Objects Daniel G. Aliaga Alvin J. Law Yu Hong Yeung
 

Summary: A Virtual Restoration Stage for Real-World Objects

Abstract
In this paper, we introduce a system to virtually restore damaged
or historically significant objects without needing to physically
change the object in any way. Our work addresses both creating a
restored synthetic version of the object as viewed from a camera
and projecting the necessary light, using digital projectors, to give
the illusion of the object being restored. The restoration algorithm
uses an energy minimization method to enforce a set of criteria
over the surface of the object and provides an interactive tool to
the user which can compute a restoration in a few minutes. The
visual compensation method develops a formulation that is
particularly concerned with obtaining bright compensations under
a specified maximum amount of light. The bound on the amount
of light is of crucial importance when viewing and restoring old
and potentially fragile objects. Finally, we demonstrate our
system by restoring several deteriorated and old objects enabling
the observer to view the original or restored object at will.
