模拟电子 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分解的S分量矩阵中， ...

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 as more
data become a ...

In the field of biometrics, palmprint is a novel but promising technology. Limited work has been reported on palmprint identification and verification, despite the importance of palmprint features. There are many unique features in a palmprint image that can be used for personal identification. Prin ...
