The Similarity Calculation of Chinese Character Glyph Based on Scale-Invariant Feature Transform
As a pictograph with large number and complex structure,the similarity calculation of Chinese char-acters is of great significance for the recognition and correction of misspellings in Chinese.In this paper,Chinese characters are treated as graphs,feature points of Chinese characters are extracted by Scale Invariant-Feature Trans-form(SIFT)algorithm,and a similarity calculation method based on feature points is proposed by using the corre-sponding relationship between feature points between characters.The similarity analysis is carried out for 8105 Chi-nese characters and the results show that this method is more consistent with the human cognitive results.
