说明： In this paper, a new scaling-based image-adaptive
watermarking system has been presented, which exploits human
visual model for adapting the watermark data to local properties
of the host image. Its improved robustness is due to embedding
in the low-frequency wavelet coefficients and optimal control of
its strength factor HVS point of view. Maximum-likelihood
(ML) decoder is used aided by the channel side information. The
performance of the proposed scheme is analytically calculated
and verified by simulation. Experimental results confirm the
imperceptibility of the proposed method and its higher robustness
against attacks compared to alternative watermarking methods in
the literature

对于一个动态系统dy/dt=-y(t)+x(t-m),m为一个时间滞后常量，x(t)、y(t)都是关于时间
t的函数，其中x是一个正态分布的数据集合，可随机产生，这样情况下，如何将系统情况
用样本点表示出来
(for a dynamic system dy/dt =- y (t) x (t-m), m for a time lag constants, x (t), y (t) are on the function of time t, where x is a normal distribution of data sets can be randomly generated, under these circumstances, how the system of sample points out)
