代码说明:

  有限差分方法(网格法)是最早使用的一种电磁场数 值计算方法。 边值问题 物理思想:场域离散。 (连续区域→网格和节点) 数学基础:差分原理。 (微商→差商) 线性代数方程组 §6-3 有限差分方法 作为数值计算方法,有限差分法将连续场域的问题变换 为离散系统的问题(连续场域划分为若干个细小的区域:网 格和节点)。也就是说通过离散化模型上各离散点的数值解 来逼近连续场域内的真实解。(The finite difference method (grid method) is the earliest use of an electromagnetic field the number of Value method. Boundary Value Problems Physical idea: the field of discrete. (Contiguous area → grid nodes) Mathematical foundations: the difference principle. (The Derivative → difference quotient) Linear algebraic equations. § 6-3 Finite Difference Method Numerical methods, finite difference method will transform the problem of the continuous field For discrete systems (continuous field is divided into several small areas: network Grid nodes). That is, the value of the discrete points in the discrete model solution To approximate the true solution of the continuous field domain.)

     数字水印技术是近年来图像保护技术研究领域的一个热点,本文提出了一种基于小波变换的图像数字 水印嵌入算法的Matlab 实现。实验结果表明,该算法具有较好的视觉效果和透明性。( Abstract  The digital watermarking technology is the most active topic in image protecting recently. In this paper , a digital watermarking algorithm based on Wavelet transform is proposed ,and give ou the program of this algorithm by MatLab. The experimental results demonstrate that the method possess good vision effect and transparence.)
