Method for identifying strokes of handwritten Chinese characters

Abstract

The invention discloses a method for identifying the strokes of handwritten Chinese characters. The method comprises the specific steps of building the feature sets of standard strokes of Chinese character, position relationships and intersection relationships; recording the writing features of the strokes of handwritten Chinese characters, and building the feature set of the strokes of handwritten Chinese characters; separating the strokes of strokes type uniqueness, so as to be matched with the standard Chinese characters; building the externally covered rectangle of the handwritten Chinese characters, equally dividing the rectangle to a plurality of sublattices, determining the sublattice of each stroke, and matching the sublattices with the standard Chinese characters according to an absolute position relationship; extracting the strokes of the handwritten Chinese characters, and matching with the standard Chinese characters according to the intersection relations, wherein the strokes of the handwritten Chinese characters and the strokes with the defined corresponding relations have intersection characteristics; calculating the relative position relations of similar strokes, and matching with the standard Chinese characters according to the similarity of relative positions; and judging the comprehensive similarity on the rest of strokes, and finally completing the building of the corresponding relations of all strokes. According to the method provided by the invention, the corresponding relationships between the handwritten Chinese characters of the user and the standard Chinese characters can be built, so that the method has an 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 method for recognizing strokes of handwritten Chinese characters. Background technique [0002] Characters are a social symbol system that records and transmits language information. As a language of the Chinese nation, Chinese characters carry the history, culture and temperament of our nation. They are the most direct inheritors of the 5,000-year Chinese civilization. And along with the popularity of computers, people are more and more dependent on computer typing, and the chances of handwriting Chinese characters are then less and less. The degree of attention and practice intensity of handwritten Chinese characters has been greatly weakened, and how to improve the writing ability of Chinese characters has become an urgent problem to be solved. [0003] At present, there are mainly the following automatic evaluation methods f...

Problems solved by technology

[0007] Although the above methods can evaluate the writing quality of handwritten Chinese characters in some aspects, these methods do not realize the one-to-one correspondence between the strokes, so it is impossible to judge the correctness of each stroke, and it is impossible to judge the correctness of the stroke order and the structure is reasonable.
