The watermark was embedded in the wavelet domain using the mean quantization method. This method can be used to detect the distortion both in spatial and frequency domain.
这种算法是采用了均值量化的方法，把数字水印嵌入图像的离散小波域，可以检测在空间域和频率域的图像失真。
Hamiltonian of magnons system was simplified by the second quantization method presented by Holstein and Primakoff. The nonlinear interaction term of Hanitltonian was dealt with by mean theory.
采用霍尔斯坦和普里马科夫提出的二次量子化方法把磁振子系统的哈密顿量简化，并应用平均场理论处理了哈密顿量中的非线性相互作用项；
Method difference F and mean value F are applied to adjust the quantization gap to make the embedded watermark adapt to the Yu carrier image much better.
方差F和均值F被用来调整量化间隔以使嵌入的水印更好地适应于载体图像。
