Spectral Image Processing and Analysis of the Archimedes Palimpsest
The Archimedes Palimpsest is a 10th-century parchment manuscript that was erased in the 13th century and overwritten with a Christian prayer book. The Walters Art Museum in Baltimore, MD, USA has supervised ten-year collaboration by conservators, imaging scientists, and scholars to image and transcribe the original writings. This paper reports on the variety of optical imaging and image processing techniques used in the project. Image analysis tools to clarify texts included supervised segmentation via a spectral pseudo inverse calculation, deterministic renderings in pseudo color, and statistical analysis with dynamical pseudo color rendering.
