Included are the files wav1.m, wav2.m, wavecoef.mat and readme.
wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the ...

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 the module). A planar-rotation algorithm is used to update the QR-
factorization. This makes it suitable for updating regressions a ...

一种新的自适应数字水印算法
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始图像分块经过SVD ...

基于视觉加权的奇异值分解压缩图像质量评价测度
摘 要：以像素值为基础的传统图像质量评价方法有其固有局限性，如对图像结构的忽视及对完全参考图像的需求等。为解决这些问题，该文研究了图像的奇异值向量对图像结构的表征能力，提出了基于视觉权重的奇异值分解和均值偏差率的部分参考图像质量评价方法BWSVD(Block Weighted Singular Value Decomposi ...
