| Summary: | 碩士 === 大同工學院 === 資訊工程研究所 === 81 === This paper presents a methodology for classifying syntactic
patterns is using a feature matching against a set of proto-
otypes. The prototypes are first classified and arranged
into a hierarchical structure that facilitates this matching.
Image of characters are described by a sequence of features
extracted from the chain codes of their contours. A rotatio-
nally invariant string distance measure is defined that com-
pared two feature strings. The methodology discussed in this
paper is compared to a nearest neighbor classifier that use
2,010 prototypes. The proposed technique can get a recognit-
ion rate of greater than 97 percent, and the recognition sp-
eed is 0.5 sec/char.
