一种低点阵字库压缩算法

A COMPRESSING ALGORITHM OF LOW DOT MATRIX CHINESE CHARACTERS LIBRARY

本文介绍一种低点阵汉字库不失真压缩还原算法。该算法在压缩对考虑了汉字本身笔划的特点,有较高的压缩比。在还原汉字、对前缀码进行译码时,给出一种映射的方法,使得译码速度提高了三倍,这种译码方法适用于所有计算机前缀码译码问题。

This paper introduces an algorithm of compressing and recovering for low dot matrix Chinese characters library. Since the unique feature of the strokes of Chinese characters is considered, the compression ratio is raised. At the same time, a mapping method is applied to recovering Chinese characters and translating prefix code.It makes the speed of translating prefix code three times faster than it used to be. The, method can be applied to all problems in computer prefix code translation,
