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 novel algorithms appealing to morphological operators are proposed. The evaluation of the methodology is performed on pages of XVI century books.Attribution 4.0 International LicenseDigital antique books, mathematical morphology, geometric features, feature extractionDigital antique booksmathematical morphologygeometric featuresfeature extraction10.2312/pt.20011322115-1228 pages
