Ben-Gurion U. developing new computer techniques to analyze historic Hebrew and Arabic documents
Date:8/14/2009

the problem, we created an algorithm to cover the text in a dark grey color, which then highlights lighter colored pixels as background space and identifies the darker pixels as outlining the original Hebrew lettering," said Prof. Klara Kedem of the Department of Computer Sciences and one of the system's creators.

Many of the new methods will apply to other languages as well, including binarization of highly degraded documents (converting up to 256 grey colors to black and white to facilitate digitization), segmentation of skewed and curved lines and word spotting in both curved and highly degraded documents. Other algorithms will be more language specific, such as paleographic analysis of Hebrew and Arabic historical documents that will include automatic indexing of document collections, determining authorship, location and date of the documents.

The research is being funded by the Israel Science Foundation (ISF). Prof. Ehrlich and other BGU scholars in the humanities will be among those to evaluate the system to be built by Prof. Klara Kedem and Dr. Jihad El-Sana of the Department of Computer Sciences and Prof. Emeritus Tsiki Dinstein from Electrical Engineering.

The group is part of the emerging global effort to understand, manipulate and archive historical documents so that they are available to researchers in paleography, archaeology and historical research.
