Technique to correct yellowing and foxing in antique books

New algorithms for the automatic restoration of antique documents affected by foxing and by yellowing deterioration processes are proposed in the paper. The physical restoration of such objects is both expensive and hard to carry out by nonspecialised library personnel. The proposed algorithms ensure fast and less expensive results, and can be used also by nonqualified operators. Moreover, thes...

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...

In this document, we use the Abstract Interpretation framework to analyze concurrent programs using Thread-Modular Analysis. We designed a relational abstraction of interferences in order to infer more properties and go beyond the state of the art. We implemented a basic analyzer, studying the numerical properties of a simple language. We present the results obtained, as well as a study of the ...
