为了提高数字水印抗击各种图像攻击的性能和保持图像的稳健性和不可见性,提出了一种基于离散小波变换(DWT),SVD(singular value decomposition)奇异值分解水印图像和原始载体图像的离散余弦变换(DCT)的自适应水印嵌入算法,主要是将水印图像的两次小波变换后的低频分量潜入到原...
The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of...
