Paper Abstract

Ancient cuneiform inscriptions are remains of historic and cultural value. The characterization of cuneiform signs by means of feature enhancement, feature extraction, detection, and identification is therefore of special interest. The use of methods minimizing the in-class objects sensitivity while maximizing the discriminability for out-of-class objects is indispensable due to the inherent sensitivity of optical pattern recognition. To analyze cuneiform inscriptions a multifunctional experimental device was advanced enabling correlation experiments to be performed including an automatic prefiltering procedure. An original technique for coherent optical averaging is introduced. The in-class and out-of-class correlation sensitivities are compared for different types of matched spatial filters including classical single sign filter, optically averaged filter, digitally averaged filter, and multiplexed filter.
