Chinese character text line writing quality automatic evaluation method and system based on time sequence point set calculation

Abstract

The invention discloses a Chinese character text line writing quality automatic evaluation method and system based on time sequence point set calculation. The method comprises the specific steps of obtaining point set data of a handwriting Chinese character text line writing track of a user; performing line division according to the obtained point set data; performing word segmentation by adoptingan image processing method according to the line division result to obtain a line axis; calculating user handwritten text line index characteristics by using the line axis description; performing quality evaluation scoring according to indexes in the handwritten text line of the user. The method can be used for judging whether the handwritten Chinese character text line of the user is neat or notand conforms to the general aesthetic principle or not, can be applied to chapter training in hard-tipped pen writing teaching, can also be used for text line personalized writing guidance and the like, and has important practical significance.

Description

technical field [0001] The invention relates to the technical field of using a computer to evaluate online handwritten Chinese character text lines, in particular to an automatic evaluation method and system for the writing quality of handwritten Chinese character text lines based on important writing features. Background technique [0002] Chinese characters are an important carrier of the history of Chinese civilization and a treasure in Chinese culture. Chinese character text works are a way that people use Chinese characters to communicate and express their thoughts, and have their own specific norms and aesthetic requirements. In the evaluation of the writing quality of a text work, the compositional layout is the primary factor, that is, the overall layout and structural arrangement of its text lines determine the overall style of the text. Therefore, the evaluation of Chinese character writing quality requires not only the evaluation at the individual character level...

[0006] 3. "Perception-Based Multi-Direction Online Handwriting Text Line Extraction" of "Journal of Computer-Aided Design and Graphics" 2007 No. 19 is based on the theory of visual perception and adopts a bottom-up strategy to establish a link model of stroke blocks. Search line arrangement results, this method can extract curved text lines, but the handwriting is required to conform to the normal writing direction, and supplementary pen behavior is not allowed, and it is also somewhat far from the actual demand

[0007] The above evaluation methods are only for individual character evaluation, and there is no evaluation method for the overall level of the text such as the writing quality of the text line
