The set of Tibetan characters consist of basic 30 consents, 76 combination characters, and 4 vowels. Despite the limited number, there are many similar characters and thus, special treatment is necessary to recognize them automatically.
In this paper, each Tibetan character is assigned to have an Object Oriented dictionary which is created by combining the categorization and the character identification procedures. When the Euclidean distance between the candidate characters becomes shorter than the assumed threshold values, these characters are categorized as similar characters.
