本代码是一些关于水印处理的一些算法用小波变换来实现，在嵌入水印之后用各种攻击检验算法的鲁棒性-The code is some deal about a number of watermarking algorithm using wavelet transform to achieve, in the embedded watermark after the attacks with a variety of test algorithm robustness

用小波实现图像的三层分解与重构,并且含有嵌入水印的程序，实现了对水印图像的各种攻击，有很好的实验结果-using wavelet to decompositiom and reconstruction image this method have an good stability and it can through kinds of attracts

the Matlab project contains the source code used for simple watermarking using wavelet transform. Performs watermarking of the input image by decomposing the image using haar wavlet. Noise generated with normal distribution is used as the key and is
