Problems solved by technology

However, there are only 3,755 Chinese characters in the national standard first-level font library of "Calibration GB_2312", plus more than 500 components in the font library. If you manually select points, not only the manual workload is huge, but also the subjective factors have a great influence, and the accuracy rate is not good. High, time-consuming and labor-intensive

Embodiment Construction

[0062] The invention also adopts the basic Chinese character component library to store the component images of Chinese characters, uses the affine transformation parameters obtained by the global affine transformation to transform the components in the basic Chinese character component library, and then forms the transformed components into Chinese characters. The basic Chinese character component library consists of the following 55 basic Chinese character component images:

[0063]

[0064] Use S to represent the components in the basic Chinese character component library, that is, the source image, and R to represent the corresponding components of the standard Chinese character image, that is, the target image:

[0065] S={s 1 ,s 2 ,...,s i ,...,s m}

[0066] R={r 1 , r 2 ,...,r j ,...,r n} (1)

[0067] the s i is the ith black pixel of S, r j is the jth black pixel point of R, and the arrangement order of the points can be arbitrar...

Abstract

The invention provides a Chinese compounding realization method based on the optimum global affine conversion. The method adopts a basic Chinese part library to store part images of composing Chinese characters, and convert the parts in the basic Chinese part library through affine conversion parameters obtained through global affine conversion, and then construct converted parts into Chinese characters. The invention designs 55 basic Chinese part images, offers the calculation method of global affine conversion parameters, and judges the structure quality of compounding Chinese images with the method of structure similarity. By the 55 basic Chinese part images and the corresponding affine conversion, the invention can construct Chinese characters at will to greatly lower the storage volume of Chinese characters.

Description

technical field [0001] The invention belongs to the field of Chinese character synthesis of information technology, in particular to a method for realizing Chinese character synthesis based on optimal global affine transformation. technical background [0002] In the information age, Chinese characters have exposed the weakness of a large storage capacity, and these weaknesses have added difficulties to the use of Chinese character fonts in various electronic products. Using hierarchical Chinese character fonts to reduce the storage capacity of Chinese character images is a feasible solution. However, in the image storage of Chinese characters, each Chinese character is composed of several parts, these parts include basic strokes, radicals and characters, basic strokes such as 一丿丿, 乚, etc. Characters such as Yugui Kuratamen, etc., many parts often appear repeatedly in different characters, so only commonly used parts are stored in the basic Chinese c...
