Research On The Correctness Judgment Method Of "anthropomorphic" Handwritten Chinese Characters Based On Template Matching

This study will focus on the realization of automatic judgment and guidance function for correctness of Chinese characters.Try to improve the non-standard tolerance rate for some calligraphic words and art words while ensuring accuracy of the judgement for correctness of Chinese characters written on mobile devices by users.And on this basis,to provide guidance on writing errors and non-standard Chinese characters in the angle of humans.This article reviews and summarizes the understanding and requirements about the correct writing of Chinese characters in history and Chinese language disciplines.Combined with the statistics on the writing errors of Chinese characters in the Chinese character writing investigation report and the summary of the early project work.This study constructs a complete set of structural characteristics system for the correctness of Chinese character.This study takes the standard template words and the set of user-written stroke trace points written on mobile devices as the research object.After preprocessing the stroke of standard template word and user's word,each feature was quantified,such as stroke morphology,stroke length,relative position and combination relationships.Then calculated to obtain the matching matrix of characteristics and give the judgement and guidance for correctness of Chinese character.The correctness judgement of Chinese character writing includes the correct output of writing and the correct matching of strokes.The judgement result of writing is achieved based on the matching of strokes.According to the matching matrix of the standard word and the user's word stroke,this method combines the weight of each feature obtained from the statistical analysis of experiments to obtain the final matching matrix of stroke,then gives the matching and correct judgement result.The correctness guidance is based on the correct matching of each stroke.If the strokes of template word and user's word cannot match one by one,then the correctness problem will be pointed out.And if the matching is successful,the matching values of each stroke's feature and the fault tolerance of corresponding feature will be compared.At the last.the guidance will point out the strokes and its feature which are non-standard,the features include the number of strokes,stroke morphology,stroke length,stroke relative position and combination relationships.The experiment showed that the method in this article was effective to standard writing,free writing,some calligraphic and art characters.It can be used in practical teaching,but some algorithms still needed to be improved.
