An Undefined Character Processing System Using Character Structure Analysis by Mathematical Morphology

摘要

In this paper, we propose a character processing system(undefined character processing system)that handles characters for which fonts or character code systems have not been provided on the terminals(unde- fined characters). The undefined characters include char- acters historically not installed din the input/output environment, such as ancient characters or characters used by minority groups, and characters not used in a particular language system environment.
