代码说明:

说明:  本文提出一种在原始视频DCT(离散余弦变换)与SVD(奇异值分解)域自适应嵌入水印的算法。算法首先将视频流分割成一个个场景,场景中的视频图像被变换到DCT-SVD域中,水印量化嵌入在最大奇异上,实现了水印盲检测。同时实验证明该算法在满足透明性要求下也满足一定的鲁棒性要求,能够抵抗低通滤波、中值滤波、椒盐噪声、高斯噪声、H.264压缩攻击以及统计攻击和帧剪切等攻击。(This paper presents an original video in the DCT (Discrete Cosine Transform) and SVD (singular value decomposition) algorithm for adaptive watermark embedding. Firstly, a video stream is divided into scenes, scenes of the video image is converted to the DCT-SVD domain, the watermark embedded in the largest singular quantification, the realization of the watermark signal. Furthermore, the experiments show that the algorithm meet the transparency requirements are met under certain robustness requirements, can resist the low-pass filtering, median filtering, salt and pepper noise, Gaussian noise, H.264 compression attacks and attacks and frame shear statistics attack.)

    该文档是matlab工具箱的安装使用手册: PSOt为PSO的工具箱,该工具箱将PSO算法的核心部分封装起来,提供给用户的为算法的可调参数,用户只需要定义好自己需要优化的函数(计算最小值或者最大值),并设置好函数自变量的取值范围、每步迭代允许的最大变化量(称为最大速度,Max_V)等,即可自行优化。(The document is the installation of matlab toolbox manual: PSOt toolbox for the PSO, the PSO algorithm toolbox to the core package and up to the user adjustable parameters for the algorithm, users only need to define their own needs better optimization function (calculated minimum or maximum), and set a good range of functions from the variables, each iteration the maximum allowable variation (known as maximum speed, Max_V), etc., can be self-optimization.)

    平面波是一种理想的电磁波,许多复杂的电磁波能分解成均匀平面波的叠加形式,研究平面波的传输问题有很强的现实意义,本文利用场匹配法和等效传输线法对平面波入射分成介质问题进行分析,计算出总的反射系数,并利用Matlab软件对频率在0-10GHz的平面波进行了仿真对比,加深了对平面波传输的理解。(Plane wave is an ideal electromagnetic waves, many of the complex electromagnetic waves can break down into a uniform plane wave superposition form, strong practical significance in the study of plane wave transmission problem, this article use field matching method and the equivalent transmission line method for plane wave incident divided into problems with media conduct analysis, calculate the total reflection coefficient, and the use of Matlab software plane wave in the 10GHz frequency simulation compared to deepen the understanding of plane wave transmission.)
