Method for judging correctness of position relation of strokes of handwritten Chinese character based on template matching

Abstract

The invention discloses a method for judging the correctness of the position relation of strokes of a handwritten Chinese character based on template matching. The method comprises the specific steps of building a whole character feature set and a part feature set of a standard Chinese character; recording handwriting of the Chinese character handwritten by a user to obtain stroke features of the Chinese character; carrying out matching comparison on whole character features of the user Chinese character and whole character features of the standard Chinese character, building the one-to-one correspondence relation between the strokes of the user Chinese character and strokes of the standard Chinese character, confirming the attribute of each stroke of the user Chinese character, and distributing the strokes of the user Chinese character into parts to which the strokes belong; carrying out matching comparison on part features of the user Chinese character and part features of the standard Chinese character, judging whether the relative azimuth relation and the distance relation between the strokes in the parts of the user Chinese character are correct, and judging whether the relative azimuth relation and the distance relation between the parts of the user Chinese character are correct. The method can be used for judging whether the position relation between the strokes of the Chinese character handwritten by the user is correct and whether the position relation between the parts of the Chinese character handwritten by the user is correct and has important value in applications of judging the writing quality of the handwritten Chinese character and the like.

Description

technical field [0001] The invention relates to the technical field of evaluating Chinese character writing by using a computer, in particular to a template matching-based method for judging the correctness of the stroke position relationship of handwritten Chinese characters. Background technique [0002] Chinese characters are a symbol system for recording Chinese language and characters, and a tool for all Chinese speakers to communicate their thoughts and feelings. It has unique charm and beauty, and is one of the oldest characters in the world. Chinese characters embody the wisdom and wisdom of the Chinese nation, carry the history of culture and civilization of the Chinese nation, contain the beautiful pursuit and integrity of the Chinese nation, and are the most precious cultural heritage of the Chinese nation. With the popularization of computers, the way people record Chinese characters has undergone revolutionary changes. The traditional pen and paper writing has b...

Problems solved by technology

[0007] Although the above methods can evaluate the spatial structure of handwritten Chinese characters and the layout relationship between strokes in some aspects, these methods cannot accurately judge whether the relative positional relationship between the user's handwritten Chinese characters and standard Chinese character strokes or components is correct, so it cannot be realized. Judgment of the correctness of the positional relationship between strokes in Chinese characters, the judgment of the rationality of the structure, and the evaluation of the overall writing quality
