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: 研究的是时空域下的水印技术.所谓时空域就是不对信号做任何频率变换而得到的信号域。对于图象载体，起信号空间也就是象素值的取值空间。单纯的谈象素实际上是不科学的，因为对同一图象点，有不同的坐标去描述它。所以，我们选择了RGB空间下的象素（RGB象素）作为分析对象，研究了基于RGB颜色空间和图象亮度空间的空域隐藏。LSB（Lest Significant Bits）的中文意思是：最不重要位，有时也称为最低有效位或简称最低位。LSB所蕴涵的信号对图象整体来说，是最不重要的。我们将这种信号在一定意义上理解为是一种冗余。这种冗余，为我们进行信息隐藏提供了宿空间。-err

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.
