A better understanding of the inner structural features (watermarks and chain line/wire intervals) of the manuscript papers of Leonardo da Vinci (1452–1519) can provide valuable information regarding chronology, geographic origins, and studio practise. For valid conclusions, however, clear representations of watermarks and chain lines/wires are required. While the easiest way to capture these unique physical characteristics of paper is via transmitted light, they can be difficult to decipher when writing and other surface marks found on the recto (front/obverse) and the verso (back/reverse) of the sheet obscure them. Using Leonardo'sCodex Leicester(Bill Gates Collection), compiled circa 1508–1510, as a case study, a computational approach was designed to minimize surface writing to enhance the watermarks and chain lines/wires detectable in the paper, by subtracting out diffuse specular (normal) light images of the recto and the verso sides from the transmitted light image. This is accomplished by posing the problem as a mathematical optimization problem, and solving for the optimal weights is fast and robust.
