Digital Restoration for Antique Documents
Abstract
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 report the results of the restoration of water blotches, foxing and creases together with a novel methodology to obtain a continuous tone image starting from an halftoned one, without knowing the original halftoning technique.
