Abstract

In the late 19th Century the Old Executive Office Building (OEOB) was constructed adjacent to the White House. Over the years it has housed many of the departments of the executive branch of the U.S. Government. By the turn of the century most of the original painted designs on its walls had been covered over with various `institutional' wall paints. In recent years there has been a move to restore may of the private and public rooms in the OEOB to their original appearance. In the case of the Office of the Vice President during a brief period when the office was vacant, the overpaints were removed in small areas to reveal glimpses of the original wall designs. These design fragments were then photographed and digitally scanned. The techniques of digital computer image enhancement were next employed to clarify, extend, replicate, and rotate these designs. An image of the office was then restored to show its original appearance. Subsequently, the office itself was restored. Before and after images of the office are presented along with the computer-generated reconstruction that guided the restoration work.
