基于部件复用的分级汉字字库的构想与实现

Hierarchical Chinese character database based on radical reuse

为减少汉字图像字库的存储量,提出了一种基于仿射变换的分级汉字字库构造的新方法。该方法设计了汉字经常使用的基本部件库,通过仿射变换重复使用这些部件来自动生成任意汉字。提出了使用仿射变换来实现部件与汉字之间的转换的方法。试验表明,该方法可行,在减小字库存储量上具有显著的优点。

In order to reduce the storage of Chinese character bitmap database, a new hierarchical Chinese character database design method based on affine transform was proposed. The basic radicals library which were frequently used was designed. Each Chinese character could be generated from the basic radicals library. Affine transform was brought forward to generate characters from radicals. Experiments show that the proposed method works very well. The storage of bitmap Chinese database can be decreased greatly by using this new method.
