【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。更多还原

【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.更多还原
