The mission of the this laboratory is to apply digital
imaging algorithms and technologies to clarify ancient
documents, including text material written on parchment
and papyrus and on and within clay tablets. Imaging
technologies including digital electronic cameras and
xerographic printers are used to gather and print images,
and image processing algorithms are developed and applied
for monochrome, color, and multispectral images.
The lab is partially funded by a Center for Advanced
Technology Grant (CAT), which is a grant program administered
by the New York State Science and Technology Foundation.
The CAT helps support the Center for Electronic Imaging
Systems, which is a joint effort of the University of
Rochester and RIT. The CAT program is intended to facilitate
and encourage economic growth in New York State by funding
promising new technologies that may lead to establishment
of new employment.
Besides the Dead Sea Scrolls, the lab also works on
the imaging of low-relief clay tablets with raking illumination
to bring out features as well as forensic imaging (image
clarification and enhancement) applied to evidence.
Bob Johnston, who is the principle scientist in the
lab, has been working in archeology for many years that
include many trips to digs in the near east. In the
course of this work, he was an early advocate of applying
imaging technologies to the study of antiquities. For
example, he was among the first to use xerographic x-ray
imaging (xeroradiography) to view structure within clay
pottery and writings on clay tablets stored within clay
containers without damaging the container. The work
with scrolls resulted from his many contacts in archeology.
