Handwritten Chinese character stroke confirmation method for carrying out similarity matching on the basis of characteristic matrix

A technology of similarity matching and feature matrix, which is applied in character and pattern recognition, instruments, computer components, etc., can solve the problem of failure to realize the relationship between strokes, the inability to judge the correctness of each stroke, the inability to realize the correctness of stroke order, and reasonable structure Sexual judgment, overall writing quality evaluation, etc.

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

Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 , a handwritten Chinese character stroke confirmation method based on feature matrix for similarity matching, comprising the following steps:

[0043] 1. Establish a feature set of stroke orientation, topological relationship and shape of standard Chinese characters;

[0044] (1) Traverse the standard Chinese character point set to obtain the minimum and maximum values ​​of the X coordinates in the point set x min 、x max , Y coordinate minimum and maximum y min 、y max , with (x min ,y min ), (x min ,y max ), (x max ,y min ), (x max ,y max ) four points to build a horizontal rectangle for the vertices. Such as figure 2 As shown, construct the intersection point p of the diagonals of the horizontal rectangle 0 as the center of the circle, with p 0 A is a circle of radius, where A is the center to p of the points that make up the...

Abstract

The invention discloses a handwritten Chinese character stroke confirmation method for carrying out similarity matching on the basis of a characteristic matrix. The method comprises the following specific steps: (1) establishing a stroke feature set based on writing direction, topological relation and shape for a certain Chinese character which is given as criteria; (2) recording the Chinese character writing trajectory of a user by utilizing a digital handwriting platform, analyzing and processing to obtain user Chinese character features, and establishing user Chinese character stroke feature matching space which is uniform with standard Chinese character stroke features for the user Chinese character features; (3) judging total similarity between certain stroke of the Chinese character and a standard Chinese stroke by taking the standard stroke feature set; and (4) if the total similarity is higher than a certain threshold value, finishing stroke matching, and otherwise, judging that matching fails and the stroke is wrongly written. One-to-one corresponding relationship judgment of a user handwritten Chinese character stroke and the standard Chinese character stroke can be realized, so that whether the user handwritten Chinese character stroke is correct can be judged, and the invention exhibits 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...
