Due to the curved shape of cuneiform tablets, inscriptions on the tablets are often not fully legible on photographs. A more readable two-dimensional representation can be achieved by applying a local filter to the high-resolution 3D-scan of the tablets. This method determines the local curvature on multiple scales by calculating the intersection of virtual spheres of different sizes with the triangular mesh of the clay tablet surface. This approach significantly improves the readability of cuneiform tablets and ancient stone inscriptions. Moreover, the GigaMesh software framework presented in this paper is able to recognize the wedge-shaped marks of cuneiform tablets and to vectorize the inscriptions.
