Digitized Watermarks in the Music Manuscripts of Franz Schubert

<p>The data set contains images taken via an infrared camera, so-called thermograms, of six music manuscripts by the composer Franz Schubert. The manuscripts themselves are kept in the music collection of the <a href="https://www.onb.ac.at">Austrian National Library</a> in Vienna: <a href="http://data.onb.ac.at/rec/AC13910894">Mus.Hs.19487</a>, <a href="http://data.onb.ac.at/rec/AC13910196">Mus.Hs.19488</a>, <a href="http://data.onb.ac.at/rec/AC13909250">Mus.Hs.19491</a>, <a href="http://data.onb.ac.at/rec/AC13909165">Mus.Hs.27666</a>, <a href="http://data.onb.ac.at/rec/AC13909150">Mus.Hs.41200</a> and <a href="http://data.onb.ac.at/rec/AC13909874">Mus.Hs.41542</a>.&nbsp;<br> Due to the large dimensions of the folios, two images per folio were usually made. These can be found in the subfolder &ldquo;orig&rdquo;. By stitching these pairs of images, the whole folios were digitally reassembled. These images are stored in the subfolder &ldquo;comb&rdquo;.</p>
