Digitization, Preservation and Character Recognition in Ancient Documents Using Image Processing Techniques – A Review

Abstract

Historical documents are considered a significant source of national heritage and societal development. It is an essential feature of society and a reference to their culture, tradition, and civilization. An imagebased information management system for the restoration of cultural heritages has been developed. Precise records of the status of a cultural heritage are necessary to preserve or restore it. The precise records of the object have been available by photogrammetric technique, but there are too few expensive photogrammetric instruments and experienced photogrammetrists at a heritage site.
