Computer aided restoration method of oracle bone rubbing font

Abstract

The invention discloses a computer aided restoration method of oracle bone rubbing font. The method comprises the following steps: scanning the fonts of a oracle bone rubbing on the paper to store in a computer; adjusting the size of the scanned picture, performing binarization processing; calculating the areas of all connected regions on the oracle bone rubbing and the number of the connected regions with the same area to obtain the distribution characteristics of the connected regions of the oracle bone rubbing, calculating the mathematical expectation of the areas of the connected regions, performing recognition processing to the areas of the regions, calculating the characteristic points of the glyph outlines of the oracle bone rubbing, calculating the end points of the stroke segments of the fonts according to the characteristic points, distinguishing different stroke segments according to the end points; performing squeezing transformation to each stroke segment of the oracle bone rubbing; and calculating the fractal dimension of each stroke segment of the fonts of the oracle bone rubbing. By using the method of the invention, time and labour are saved; and the method is convenient and fast, has good restoration effect and is suitable of the restoration of the fonts of oracle bone rubbings.

Description

technical field [0001] The invention relates to a method for restoring glyphs of oracle bone inscription rubbings. Background technique [0002] Oracle bone inscriptions are characters carved on hard tortoise shells and animal bones, so the strokes carved are thin and straight, with sharp ends, and the turning points are often connected by two straight lines to form an inflection shape, forming a square brush. Because the texture of the tortoise shell and animal bone itself is not as smooth as a mirror, and it has been buried deep underground for thousands of years, due to corrosion, excavation damage, and transportation contamination, there are many noise spots on the oracle bone, and the edges of the glyphs have faded. Very blurry and has lost its original appearance, such as figure 1 , figure 2 , image 3 as shown, Figure 4 is the contour map of the oracle bone rubbing image. [0003] Such defaced glyphs cannot be further used in the construction of oracle bone gly...
