Results for laid line extraction of two different papers, the left images in each box show the reflected light image and the right images the spectral TV decomposed images with the detected lines drawn. a Patch taken from The Parker Library, Cambridge, Corpus Christi College, MS 100: Transcripts (16th century). Simeon of Durham OSB. Geoffrey of Coldingham OSB. Tito Livio Frulovisi. Walter of Guisborough OSA. Asser, p. iiv. The laid line density measured in the 1 cm section marked by the red line is 8 lines per cm. b Detail from Cambridge University Library, MS Ii.5.41, fol. 336r.
