“…SFF is a widely used technique, especially at microscopic level while applications at macroscopic level are relatively recent [12]. To the best of our knowledge, there have been very few applications in cultural heritage, once again generally at the microscopic level [13,14]. Basically, SFF produces 3D maps based on a stack of 2D images, obtained by varying the camera-object distance.…”

This work illustrates the use of three different digitization techniques in order to study and valorize a 15th century engraved tablet discovered during a preventive archaeological excavation in the area of a former convent. The tablet is covered with engraved inscriptions on both sides, and includes a musical score. Digitization allowed for an advanced analysis of the inscriptions, and to generate a complete and precise 3D model of the artifact which was used to produce an interactive application deployed both on tactile tablets and website. The interactive application integrates a musical interpretation of the score that gives access to a testimony of intangible heritage. This interdisciplinary work gathered archaeologists, researchers from computer science and physics, and a professional musician. CCS Concepts: • Applied computing → Arts and humanities; • Computing methodologies → Computer graphics.

“…Focus variation microscopy has been demonstrated, for instance to analyse punchmarks on medieval panel paintings [22], and to evaluate its usefulness in supporting painting cleaning [23]. Both studies have only used this technique to capture small areas, rather than 3D imaging larger regions or complete paintings.…”

A seventeenth-century canvas painting is usually comprised of varnish and (translucent) paint layers on a substrate. A viewer's perception of a work of art can be affected by changes in and damages to these layers. Crack formation in the multi-layered stratigraphy of the painting is visible in the surface topology. Furthermore, the impact of mechanical abrasion, (photo)chemical processes and treatments can affect the topography of the surface and thereby its appearance. New technological advancements in non-invasive imaging allow for the documentation and visualisation of a painting's 3D shape across larger segments or even the complete surface. In this manuscript we compare three 3D scanning techniques, which have been used to capture the surface topology of Girl with a Pearl Earring by Johannes Vermeer (c. 1665): a painting in the collection of the Mauritshuis, the Hague. These three techniques are: multi-scale optical coherence tomography, 3D scanning based on fringe-encoded stereo imaging (at two resolutions), and 3D digital microscopy. Additionally, scans were made of a reference target and compared to 3D data obtained with white-light confocal profilometry. The 3D data sets were aligned using a scale-invariant template matching algorithm, and compared on their ability to visualise topographical details of interest. Also the merits and limitations for the individual imaging techniques are discussed in-depth. We find that the 3D digital microscopy and the multi-scale optical coherence tomography offer the highest measurement accuracy and precision. However, the small field-of-view of these techniques, makes them relatively slow and thereby less viable solutions for capturing larger (areas of) paintings. For Girl with a Pearl Earring we find that the 3D data provides an unparalleled insight into the surface features of this painting, specifically related to 'moating' around impasto, the effects of paint consolidation in earlier restoration campaigns and aging, through visualisation of the crack pattern. Furthermore, the data sets provide a starting point for future documentation and monitoring of the surface topology changes over time. These scans were carried out as part of the research project 'The Girl in the Spotlight' .
