Recognition of vertical vowel graphemes of Korean characters based on combination of vowel graphemes

摘要

Korean characters consist of 2-dimensional-distributed consonantal and vowel graphemes. The purpose of reducing the 2-dimensional characteristics of Korean characters to linear arrangements at early stage of character recognition is to decrease the complexity of following recognition task. By defining the identification codes for the vowel graphemes of Korean characters, the rules for combination of vowel graphemes are established, and a recognition algorithm based on the rules for combination of vowel graphemes, is therefore proposed for vertical vowel graphemes. The algorithm has been proved feasilbe through demonstrating simulations.
