Handwritten Chinese character homonymous stroke extraction method based on position constraint

Abstract

The invention belongs to the technical field of image processing, particularly relates to a handwritten Chinese character homonymous stroke extraction method based on position constraint, which aims to solve the problem of low extraction applicability and accuracy due to the fact that stroke arrangement is not considered in extraction of homonymous strokes of handwritten Chinese characters. The method comprises the following steps of acquiring a handwritten Chinese character image and a reference Chinese character image, respectively centrally placing foreground areas of the handwritten Chinese character image and the reference Chinese character image in the two empty images to serve as a first image and a second image, obtaining a segmented connected region of the first image, traversing the segmented connected region of the first image, and adjusting the position of the reference stroke in the second image, obtaining a homonymous stroke connected region in the first image, and outputting a point set corresponding to the homonymous stroke connected region and the outer contour thereof. The method solves the problem that extraction of homonymous strokes of handwritten Chinese characters needs to pay attention to overall fonts and consider stroke arrangement, and improves applicability and accuracy of extraction of homonymous strokes of handwritten Chinese characters.

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:
