Jia Gu Wen characters carved on turtle backs or animal bones with the featu
res of drawings are the most ancient Chinese characters used about 3000 yea
rs ago. This paper proposes a theory and technique for Jia Gu Wen character
recognition based on coding. The key idea is to treat a Jia Hu Wen charact
er as a non-directed graph. Its topological features are extracted to be th
e basis of recognition. The approach proposed in this paper is also applica
ble to character recognition of other languages such as Japanese, Korean, M
ongolian or Tibetan. (C) 2000 Academic Press.
