Digital Restoration for Antique Documents
Sebastiano Battiato, Filippo Stanco · 2007
Different advantages stem from the digital restoration of documents of high cultural value. In this paper different techniques to digital restoration of antique documents are reported. In particular, we address the problem of virtual restoration of photographic prints. We propose a classification of defects related to their origin presenting also some non linear techniques able to restore the more diffused ones. In particular we briefly report some restoration results of water blotches, foxing and creases with some more details for a novel methodology to obtain a continuous tone image starting from an halftoned one, without no knowledge of the original halftoning technique. 1
