Low-pass filters allow the low frequency components of an input signal to pass through while attenuating (reducing) high frequency components. Measurement noise fall into the high frequency range of the signal spectrum, while the underlying process signal usually lies towards the low frequency end. Thus filters that are used to remove noise from measurements are of the low-pass types. This program uses Chebyshev FIR low pass filter based on antenna theory approach to filter noise from human speech signal.

求解Chen系统的最大lyapunov指数。求解方法为定义法。两条相轨线的步长为初设距离d0的基础上加上相对分量。求解时直接运行chen_lyapunov.m即可。可移植性强，比如换求其他系统的最大lyapunov指数，只需要改变变量数目，方程即可。(Solving the maximum lyapunov index Chen system. Solving method for defining method. Plus the relative weight of the two basic steps of the phase trajectories for the preliminary design of the distance d0. Can be run directly chen_lyapunov.m solving. Portability, such as changing the index for the largest lyapunov other systems, you only need to change the number of variables, the equation can be.)

自己做的一个滤波程序，相对比较简单，希望大家一起学习(A filter to do its own procedures, is relatively simple, I hope everyone learning together)

对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)

说明：  隐马尔科夫模型的实现，可以使用的，很简单(hmm，is very simple)

CS中一个关于图象与二进制数据处理到数据庫的程序集合是一个好(on a binary image and data processing procedures to the database is a good pool Eastern)
