Description: 用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，-Using matlab realize the number of LSB-based watermarking algorithm. Algorithm can be embedded BMP gray image watermark, watermark information for the binary image, and its expansion to the original image the same size, the repetition of embedding, improve robustness. At the same time algorithm PSNR values are given to evaluate the effect of watermark images,

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. Comparison of the effect of insertion through my_hist.m to display the document.

Description: 图像的组成无非是一些字符串或者一些字节组成的字符串，然而，每一个字节数据位的重要度并不是一样的，两个相邻字节往往只有低位是不一样的。例如：00100110和00100111代表了两个不同渐变度的红色，但是就人眼是分辨不出来的。最低有效位LSB算法，就是利用这一点，达到图像压缩，或者数字水印的功能。-The composition of the image is nothing more than some number of bytes or string composed of string, however, one byte for each data bit is not an important degree of the same, often only two adjacent low-byte is not the same. For example: 00100110 and 00100111 represent the gradient of two different degrees of red, but on the human eye is not out to tell. Least significant bit LSB algorithm, is to take advantage of this point, to achieve image compression, or digital watermark feature.
