@mastersthesis{Hoffman2003_0,<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Abstract = {Ancient documents of cultural significance are often illegible. In some cases,writing was purposefully defaced or removed or has been damaged by mold. This is the case with the Archimedes Palimpsest, a 1200-year-old manuscriptcontaining the oldest known copies of several scientific treatises by Archimedes. The parchment on which the treatises were copied were erased and overwrittenwith a prayer book, the Euchologion, about eight hundred years ago. Since the Palimpsest is of cultural significance research teams are working on applyingvarious methods to enhance the legibility of the underwriting. These methods have largely ignored the techniques available to and used by analysts ofremotely sensed data. Analysts use a number of different techniques to exploit remotely sensed data,including Spectral Angle Mapping, Principal Component Analysis, and target detection algorithms based on a Generalized Likelihood Ratio Test. Thesetechniques were applied to 16-band images of the Archimedes Palimpsest to locate the poorly legible underwriting with the goal of making it easier for scholarsto read the overwritten manuscript. The results are largely qualitative, since success is determined by improving legibility over other available techniques.Initial results, while not conclusive until studied by scholars, are encouraging.},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Address = {Rochester, New York, United States},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Author = {G Hoffman},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Keywords = {restoration},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Month = {},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;School = {Rochester Institute of Technology, College of Science, Center for Imaging Science},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Title = {The Application of Spectral Methods of ImageExploitation to Document Restoration},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Type = {M.S.
