Embodiment Construction

[0086] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0087] like figure 1 Shown, a method for extracting single-character strokes in a calligraphy work, the extraction method includes:

[0088] S1, using the skeleton crawler unit to obtain the skeleton strokes of individual characters in calligraphy works. The step S1 includes:

[0089] S1.1, if Figure 2a As shown in the figure, the image of the calligraphy works scanned is processed, and the skeleton and contour extraction of the individual characters in the calligraphy works are performed.

[0090] In the present invention, step S1.1 includes:

[0091] Perform denoising and background color removal processing on the calligraphy works image, and extract the binary image of the individual characters in the calligraphy works.

[0092] Perform binarization processing on the binarized image of the above-mentione...

Abstract

The invention discloses a method for extracting single-character strokes in calligraphy works. The skeleton strokes of individual characters in calligraphy works are obtained by using a skeleton crawler unit, the stroke width of each stroke of the original single-character in calligraphy works is calculated, and the minimum enclosing area of ​​the outline of the skeleton strokes is obtained. , analyze the relationship between different types of skeleton intersections and the minimum enclosing area of ​​the stroke outline, locate the shared area and determine the type of the shared area, and complete the stroke extraction according to the type of the shared area and the minimum enclosing area of ​​the skeleton stroke outline. The invention can lay a foundation for stroke-based calligraphy character recognition, calligraphy style comparison, and authenticity identification of calligraphy works. By adopting the algorithm provided by the invention, single-character strokes in calligraphy works can be completely extracted, and a stroke extraction method is provided for stroke-based calligraphy character classification, recognition, reconstruction, animation simulation and other related research and applications.

Description

technical field [0001] The invention relates to a character image processing method, in particular to a method for extracting single-character strokes in calligraphy works. Background technique [0002] Strokes are the basic elements that compose and characterize characters, and are the basis of character classification, recognition and retrieval. Chinese characters are composed of strokes and radicals, written from top to bottom, left to right, and arranged in a two-dimensional manner. Classification and recognition of text is generally based on stroke elements. Calligraphy is a kind of handwriting. Western calligraphy is written with a flat pen, and Chinese calligraphy is usually written with a brush. Both are still in teaching practice. The biggest feature of Chinese calligraphy is that the strokes of calligraphy are not like those of printed characters: they are horizontal and vertical, and each stroke or letter has a fixed template. In the brush calligraphy of Chines...
