Minisymposium: Image Analysis Methods for Industrial Applications Digital Restoration for Antique Documents

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 m...

A Method for Improving the Visual Quality of Digitized Antique Books

In this paper we propose an algorithm which improves the quality of the digital version of antique books. In particular, we suggest a technique that enhances the virtual quality of the paper, eliminates some defects and improves the performance of Optical Character Recognition (OCR) operators.

Automatic Feature Extraction on Pages of Antique Books Through a Mathematical Morphology Based Methodology

This paper presents a mathematical morphology based methodology to identify and extract several components on antique printed books in order to automatically build metadata. These components were previously classified into five different sets (drop capitals, stripes, figures, annotations and text matter) each one characterised by particular geometric features. Based on that assumption several n...
