Simple Kalman Filter 一个简单的C语言实现的卡曼滤波器。(Simple Kalman Filter with a simple C language implementation of the Kalman filter.)

估计Hurst指数的matlab代码，可以分析股票市场上的特点。(estimate hurst exponent)

features in time domaim for signal processing

三电平逆变器可以采用PWM控制或者SVPWM控制(three level inverter which can use pwm control)

数字图像水印的攻击、嵌入、提取MATLAB源码(Digital Image Watermarking attack, embedded, source extraction MATLAB)

说明：  在地球物理勘探中将原始的SEG-Y数据导入(In geophysical exploration will be the original SEG-Y data import)

基于灰度梯度最大熵的分割方法，先通过聚类进行改进做初分割然后再进行细分割。(Segmentation of gray gradient based on maximum entropy, first through the clustering is improved. At first, then the fine segmentation segmentation.)

小波包分析提取振动信号中的特征频率，最终的权值矩阵就是滤波器的系数，可直接计算得到多重分形谱。( Wavelet packet analysis to extract vibration signal characteristic frequency, The final weight matrix is ??the filter coefficient, It can be directly calculated multi-fractal spectrum.)

DCT数字图像水印算法的源代码！含有图像的水印的嵌入和水印的提取！(DCT digital image watermarking algorithm source code! Containing the watermark image watermark embedding and extraction!)

本代码的方法是借助旋转不变技术估计信号参数(Estimation of Signal Parameters via Rotational Invariance Techniques)，现已成为谐波恢复（即正弦波个数及频率估计）的一种主要特征分解法。(This code is to help the estimated ESPRIT signal parameters (Estimation of Signal Parameters via Rotational Invariance Techniques), has now become the harmonic retrieval (that is, the number and frequency sine wave estimated) of one of the main characteristics of decomposition.)
