本文主要讲的是图像变化中所使用的小波变换的一些基本知识(This article is primarily concerned with changing the image used in some of the basics of wavelet transform)

用MATLAB实现SAPSO、SecPSO、SecVibratPSO算法，程序没错误，可以直接运行，非常适合刚学PSO者(Implementation of SAPSO, SecPSO, SecVibratPSO algorithm with MATLAB, the program no error, can be directly run, very suitable for just learning PSO )

Heritrix官方开发文档，crawler.archive.org/articles，提供了基本的类的开发介绍。((Heritrix official development documents, crawler.archive.org/articles, provides a basic introduction class development.))

分步傅立叶法计算高斯光脉冲在 光纤中的传播 考虑二阶色散(Split-step fast foruier method)

潮流计算C++程序，计算ieee4 5 14 30 57 118 300(Power Flow calculation program)

代码里有很完整的注释和解释，是小学期课程设计的题目，预报误差法参数辨识-松弛的思想，微分方程组数值解方法，添加噪声处理。(Code, there are very complete notes and explanations Is the topic of the elementary school stage curriculum design, Prediction Error Method for Parameter Identification- the idea of relaxation, Numerical solution of differential equations method, Add noise processing.)

2048matlab代码。。。。。。。。。。。。。。。。。。。。。。。(2048 the matlab codes of 2048.)

利用patchwork方法，嵌入0-1水印。可设置像素修改值、选择各种经典的攻击方式和控制攻击强弱。返回提取的水印信息和峰值信噪比。利用Matlab编写。(The use of patchwork approach, embedding the watermark 0-1. Modify pixel values can be set to choose a variety of classic attacks and control the strength of the attack. Back to extract the watermark information and peak signal to noise ratio. Prepared using Matlab.)

本程序用于测量增强语音与纯净语音的对数谱距离，用于语音增强。对数谱距离越小，表明增强语音与纯净语音越接近，增强语音质量越好；反之，则增强语音质量越差。(Calculates the average log-spectral distance between CLEAN and NOISY signals. Frames are 25ms long with 60 percent (15ms) overlap, hamming windowed. RS is the remove silence option (default: 0) if 1, the program uses a Voice Activity Detector to find non-speech frames and eliminates them from calculation of LSD. FS is the sampling frequency (Default 10KHz). )

说明：  基于非线性PCA准则的两个盲信号分离算法， 利用矩阵广义逆递推得到一种盲信号分离算法，采用梯度下降算法和线性寻优而得到另一种自适应盲信号分离算法(sourceseparation based nonlinear pca princple)
