A method for extracting strokes with the same name in handwritten Chinese characters based on position constraints

Abstract

The invention belongs to the technical field of image processing, and specifically relates to a position-constrained method for extracting strokes of the same name in handwritten Chinese characters. question. The method of the present invention includes: obtaining the handwritten Chinese character image and the reference Chinese character image; centering the foreground areas of the handwritten Chinese character image and the reference Chinese character image respectively in two empty images as the first and second images; obtaining the segmented and connected images of the first image area; traverse the segmented connected area of ​​the first image, and adjust the position of the reference stroke in the second image; obtain the connected area of ​​the stroke with the same name in the first image; output the point set corresponding to the connected area of ​​the stroke with the same name and its outer contour. The invention solves the problem that the stroke extraction of handwritten Chinese characters with the same name needs to pay attention to both the overall font and stroke arrangement, and improves the applicability and accuracy of the stroke extraction of the handwritten Chinese characters with the same name.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for extracting strokes of handwritten Chinese characters with the same name based on position constraints. Background technique [0002] Practicing hard pen calligraphy and writing Chinese characters in a standardized and beautiful way is helpful to a person's study and work. At present, the feedback and guidance for students' calligraphy practice work mainly depends on the manual. When a large number of practice work needs to be given guidance, the problem of low efficiency and heavy tasks is prominent. Therefore, intelligent means are needed to provide timely and effective pertinence to students' calligraphy work Guiding opinions to improve the effect of students' calligraphy practice. [0003] To give guidance on the regularity of each stroke and frame structure of handwritten Chinese characters, it is necessary to accurately identify each stroke...

Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the current extraction of strokes of handwritten Chinese characters with the same name without considering the arrangement of strokes, the applicability and accuracy of the stroke extraction of handwritten Chinese characters with the same name are low, and it is impossible to accurately guide students to the stroke level. To solve the problem of writing Chinese characters, the present invention proposes a method for extracting strokes of handwritten Chinese characters with the same name based on position constraints. The method includes:
