- Abstract:
-
A new method is proposed for on-line Kanji handwriting recognition. The method employs sub-stroke HMMs as minimum units to constitute Kanji characters and utilizes the direction of pen motion. The present approach has the following advantages over the conventional methods that employ character HMMs. 1) Much smaller memory requirement for dictionary and models. 2) Fast recognition by employing efficient sub-stroke network search. 3) Capability of recognizing characters not included in the training data if defined as a sequence of sub-strokes in the dictionary. In experiments, we have achieved a correct recognition rate of above 96% by using JAIST-IIPL database that includes 1,016 educational Kanji characters.
