利用DCT域进行扩频水印的嵌入,含实验图像，和各种经典的攻击方式。可选择嵌入强度和攻击强度。利用Matlab编写(DCT domain using spread-spectrum watermark embedding, with the experimental images, and various classical attacks. The option embedded in the strength and intensity of attacks. Prepared using Matlab)

基于小波变换的图像增强算法,我从专业数据库上下载的，应该有用(Based on wavelet transform image enhancement algorithm, I download on from the major databases, it should be useful)

计算多层膜的反射率，可计算不同的偏振态。各个膜层的厚度和折射率可以自己设置。(multilayer,optical film,reflection)

根据条形光波导折射率数据，分别针对宽高比a:b为1:1与 2:1两种情形，设计分析 ： 1. 满足单模与双模传输的 波导尺寸范围。（需要 给出色散曲线） 2. 针对两种情形，选取你 认为最佳的波导尺寸， 计算对应的模折射率。 （计算时假设上、下包 层均很厚）(According to the refractive index of the optical waveguide stripe of data, respectively, for an aspect ratio of a: b is 1: 1 and 2: 1 both cases, the design and analysis: 1. Meet single-mode and dual-mode transmission Bird size range. (need Given dispersion curve) 2. For both cases, you select That the best of the waveguide dimensions, Computes the corresponding mode refractive index. (Calculations assume that when the upper and lower package Layers are very thick))

说明：  是自己论文中编写的无线传感器网络中簇间路由分层次通讯方法的matlab仿真代码，可以直接出生存期图。很多论文都用这个思想。(Matlab simulation, an improved version of the leach agreement between the clusters, the passing of a hierarchical routing protocol to send a message, many papers use this thought, just write and run directly displayed a life cycle)
