dct based visible watermarking algorithm

wavelet based watermarking with dwt2 function in matlab it s an implementaton of an ieee paper.its a visible watermark it calculates the peak signal to noise ratio and the mean square error

利用MATLAB软件完成基于离散余弦变换（DCT）的可见水印算法，实现可见水印的嵌入-discussed the mathematical manipulation method of visible digital watermark and realized the visible digital watermarking inserting by completing the watermark algorithm，which based discrete cosine transform

this algorithm to do visible watermarking in this the step by step procedure is explained cleary to do visible watermarking in matlab-this is algorithm to do visible watermarking in this the step by step procedure is explained cleary to do visibl
