一种基于二值图象压缩编码前处理的新观点和新方法
摘 要
从数学角度出发，提出了一种方案：对在二值图象中影响WBS编码、块编码效率的黑直线段（铅直或水平），进行编码前的预处理，消除黑直线段。从而提高它们的压缩比。

A New Method of Biwary Image Compression
() Abstract
In this paper, an algorithm based on mathematics for improving the efficiency of WBS coding and
block coding of binary image is presented. The basic principle is to eliminate the black straight line sectors (vertical or horizontal) by preprocessing them before encoding, the compression ratio is then increased.
