Description: 此包中是对lsb这种数字水印的添加算法的一种改进方法，其中有三个主要文件Mylsb.m modify_lsb.m和.modify_lsb2.m 这三个文件是对lsb这个算法的三次不同程度的改进，一次比一次改的多，主要涉及的改进方法是我们在添加水印时运用了像素的八临域来判断所应插入的值，其次的方法是运用了转换到不同色彩空间进行水印插入。插入效果的比较通过my_hist.m这个文件来进行显示。-This package is lsb add this digital watermarking algorithm for an improved method, of which there are three key documents Mylsb.m modify_lsb.m and. Modify_lsb2.m these three documents is the lsb of this algorithm three different degrees of improvement of , one of the more than one change, mainly involving the improvement method is to add a watermark when we used the eight pixels to determine the clinical domain of the value should be inserted, followed by the method is to use a switch to a different color space for watermark insertion.
