Image Processing of Ancient Documents

I am collaborating with Dr. Keith Knox of Xerox, Dr. Robert Johnston of RIT, and others efforts to use the technologies of electronic imaging to clarify the writings of degraded ancient documents, including various of the Dead Sea Scrolls, the Archimedes Palimpsest, and the Khaboris Codex, and others.

Temple Scroll:
The Temple Scroll was discovered in 1947 in Cave 11 near Qumran. It is the longest of the Dead Sea Scrolls -- originally 28' long in 67 columns. We processed color transparencies of images taken by Bruce and Ken Zuckerman. We projected the 3-D color data at each pixel (i.e., the RGB gray values) to an opponent color space (luminance, red-green, and blue-yellow) From these images, we have been able to distinguish 18 characters that had not been recognized previously by Biblical scholars.Our efforts to clarify the so-called Temple Scroll were reported in Optics and Photonics News, 8(8), pp. 30-34, August 1997.

Archimedes Palimpsest

Khaboris Codex

The Khaboris Codex is the oldest known copy of the New Testament written in the original Aramaic, dating from the 10th century. We are cooperating with Michael Ryce to image the manuscript and develop a public website where the images would be available for scholarly study.

Colophon from JTSA
We have collaborated with Evelyn Cohen from the Jewish Theological Seminary of America to reveal the writing on the Colophon, a page of dedication from the scribe to the patron. A short summary of this work is included in the attached Word Document.
