Stroke confirmation method of handwritten Chinese characters based on feature matrix for similarity matching

Abstract

The invention discloses a handwritten Chinese character stroke confirmation method based on feature matrix for similarity matching. The specific steps are: (1) establishing a stroke feature set based on writing orientation, topological relationship and shape for a given Chinese character as a judgment standard; (2) Use the digital handwriting platform to record the user's Chinese character writing trajectory, analyze and process the user's Chinese character features, and establish a user's Chinese character stroke feature matching space that is unified with the standard Chinese character stroke features; (3) Judgment based on the standard stroke feature set The total similarity between a stroke of a user's Chinese character and a stroke of a standard Chinese character; (4) If the total similarity is greater than a certain threshold, the stroke is matched; otherwise, the matching is considered to be a failure, and the stroke is written incorrectly. The method of the invention can realize the one-to-one correspondence judgment between the strokes of the handwritten Chinese characters of the user and the strokes of the standard Chinese characters, thereby realizing the judgment of whether the strokes of the Chinese characters handwritten by the user are correct or not, and has important application value.

Description

technical field [0001] The invention relates to the technical field of evaluating Chinese character writing by using a computer, in particular to a handwritten Chinese character stroke confirmation method for similarity matching based on a feature matrix. 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 been gradually replaced...

AI Technical Summary

Problems solved by technology

[0007] Although the above methods can evaluate the writing quality of handwritten Chinese characters in some aspects, these methods have not realized the one-to-one correspondence between strokes, so it is impossible to judge which strokes are overwritten or missing, and it is impossible to check the correctness of each stroke. Judging the correctness of the stroke order, the rationality of the structure and the evaluation of the overall writing quality cannot be realized
