数字水印matlab程序，只是简单的svd跟最简单的置乱方法Arnold的应用。没有用到小波算法。上传的dwt_svd_GUI.rar是完整的数字水印算法，用的是混沌加密。(Matlab digital watermarking process, with the svd simply the easiest way to Arnold scrambling applications. Wavelet algorithm is not used. From the dwt_svd_GUI.rar is a complete digital watermarking algorithm, using a chaotic encryption.)

说明：  图像的双线性插值放大算法中，目标图像中新创造的象素值，是由源图像位 置在它附近的2*2 区域4 个邻近象素的值通过加权平均计算得出的。 双线性内插 值算法放大后的图像质量较高，不会出现像素值不连续的的情况。然而次算法具 有低通滤波器的性质，使高频分量受损，所以可能会使图像轮廓在一定程度上变 得模糊。 (Bilinear interpolation algorithm to enlarge the image, the target image in the newly created pixel value is determined by the source image position in its area near the 4 2* 2 the value of neighboring pixels calculated by the weighted average. Bilinear interpolation algorithm to enlarge the image quality after the high pixel value does not appear the situation is not continuous. However, sub-algorithm has low-pass filter nature of the damage to the high frequency components, it may make the image contour to some extent become blurred.)

Parzen窗法 模式识别基本程序 很重要很有用的哦(The Parzen window pattern recognition procedures very useful Oh)

这个是使用spss分析的一个关于快递业务满意度的一个调查分析(This is the use of SPSS analysis on an express service satisfaction an investigation analysis)

NWFE:Nonparametric Weighted Feature Extraction for Classification，线性分类方法，类似于改进了了的LDA，使用中，结果有时候比SVM等好(classification, NWFE:Nonparametric Weighted Feature Extraction for Classification)

PFC 的原理与分析设计 我们作比赛的资料(Principle and Analysis of PFC design we make the game data)

这是code使用说明,对大家比较有帮助，新手必备(This is the code for use)

说明：  拉丁超立方采样包括还有约束和没有约束的两种。(Latin hypercube sampling includes both constrained and unconstrained sampling.)
