Abstract
In the northern part of Thailand since 1802, Lanna characters were popular as ancient characters. The segmentation of printed documents in Lanna characters is a challenging problem, such as the partial overlapping of characters and touching characters. This paper focuses on only the touching characters such as touching between consonants and vowels. Segmentation method begins with the horizontal histogram and then vertical histogram for segmentation of text lines and characters, respectively. The results are characters consisted of correct clear characters, partial overlapping characters, and touching characters. The proposed method computes the left edge junction points and right edge junction points. Then find their maximum numbers and find the value of its row to separate consonant and vowel from touching. The trial over the text documents printed in Lanna characters can be processed with an accuracy of 95.81%.
