Problems solved by technology
[0004] Although there are currently existing font processing technologies that can be used to process modern Chinese characters, but because oracle bone inscriptions have their own glyph characteristics, which are different from regular modern Chinese characters, the oracle bone glyph processing technology is far more complicated than that of modern Chinese characters, and the generation of oracle bone glyphs cannot be simple. Applying modern Chinese character glyph production technology, a glyph technology that is more suitable for the shape characteristics of oracle bone inscriptions is needed
Otherwise, the generated glyphs will have glyph distortion due to the enlargement and reduction of the curve

Embodiment 1
[0042] Embodiment 1: First, image preprocessing operations such as denoising, image segmentation, and smoothing are performed on the original rubbing image of the oracle bone inscription to obtain a binary image of the oracle bone inscription text; then contour extraction and tracking are performed to obtain discrete data of contour points; finally The feature point information required in the curve fitting process is selected through the set judgment rules. These feature points reflect the characteristics of the oracle bone glyph outline curve and are used for the initial segmentation of the curve fitting. The whole method can be mainly divided into the following steps, the flow chart is as follows: figure 1 shown.
[0043] 1. Image Segmentation
[0044]An image segmentation method based on iterative threshold method is adopted. And perform binarization according to the threshold value generated by self-adaptation, that is, convert the segmented text target into a pixel val...

The invention discloses an automatic generation method of parameter-adaptive oracle-bone inscription contour glyphs, comprising the following steps: preprocessing an oracle-bone inscription rubbing image; extracting characteristic points on an original contour curve, wherein, the characteristic points comprise angular points and segmentation points; fitting the contour curve with a cubic B-spline curve, and reversely obtaining a control point of the cubic B-spline curve according to the information of the characteristic points; solving the shape parameter value of a cubic B-spline basis function with the minimum total distance deviation from discrete points corresponding to the original contour curve by adopting a least square method; and fitting the cubic B-spline curve according to the control points and the shape parameter value to obtain the needed oracle-bone inscription glyph contour curve. The oracle-bone inscription glyph contour curve generated by the method has the characteristics of small storage content, low distortion rate and high precision and is capable of greatly reducing the process of manual intervention.
Description
technical field [0001] The invention relates to a graphics processing method, in particular to a method for automatically generating outline curves of oracle bone script graphics. Background technique [0002] Oracle bone inscriptions are the earliest systematic writing in my country and one of the oldest pictographs discovered so far. The period when oracle bone inscriptions were produced was still in the painting stage, and the grammatical rules embodied in them are the earliest sources of Chinese grammar that can be traced back. People's research on oracle bone inscriptions has achieved certain results, and the textual research and interpretation have also partially explained its meaning. With the continuous development of modern science and technology, how to use computer technology to digitize oracle bone inscriptions to better inherit this traditional culture and develop this treasure on the basis of protection has very important historical significance and cultural h...
